Statistical arbitrage strategies attempt to profit from short-term price discrepancies between similar securities. Common statistical arbitrage strategies used by hedge funds include pairs trading, which involves buying an underperforming stock in a pair and short selling the overperforming stock, and multi-factor models that select stocks based on correlations to identified market factors. Other strategies include mean reversion trading, which bets that stock prices will revert to their average value, and cointegration, which tracks indexes and uses optimized portfolios to generate returns from spreads between enhanced and basic indexes.
This document provides an overview of statistical arbitrage (SA) strategies and their application to 130/30 products using synthetic equity index swaps. It begins by discussing the efficient market hypothesis and how SA circumvents some of its limitations. It then describes various SA trading strategies, including pairs trading, stochastic spread approaches, cointegration approaches, high frequency strategies, and behavioral strategies. The document applies some of these SA strategies to 130/30 products using synthetic index swaps and finds they can improve the risk-return profile of active equity management.
The document provides an overview of capital markets and financing methods for companies. It discusses the primary and secondary market, and how companies can raise long-term funds through public issues, privileged subscriptions, and private placements. It explains the roles of investment bankers and underwriters in issuing securities. Other topics covered include calculating the theoretical value of rights, SEC registration, shelf registrations, and the signaling effects of issuing new securities.
Forward and futures contracts allow parties to lock in a price today for an asset to be purchased or sold in the future. Futures contracts are traded on exchanges and include margin requirements and daily price adjustments to account for price changes, while forward contracts are negotiated privately. These derivatives can be used to speculate by betting on price movements or to hedge and reduce risk from price changes in assets a party needs to buy or sell. The document compares using futures versus options for hedging and speculating purposes.
1) The document analyzes how different investment horizons and herding behavior impact investor returns over multiple market cycles from 2001-2008.
2) It tracks sales volatility and changes in investor herding to identify phases where returns were most impacted by shifts in sentiment.
3) The analysis finds that discipline around selling, rather than buying, had a greater impact on returns. Investors with medium-term horizons of 2-5 years tended to perform best when taking a bearish stance, while bullish investors favored longer horizons of 5+ years.
Derivatives are financial contracts whose value is derived from an underlying asset such as stocks, bonds, commodities, currencies, or market indexes. The document discusses various types of derivatives including forwards, futures, options, and swaps. It explains how derivatives are used for hedging, speculating, and arbitraging. It also discusses key concepts related to pricing derivatives, hedging strategies, and the growth of the derivatives market in India.

A Presentation on Financial Derivatives. this covers it's definition, features, types, benefits, challenges and applications.
Derivative is defined as the future contract between two parties. It means there must be a contract-binding on the underlying parties and the same to be fulfilled in future.
Normally, the derivative instruments have the value which is derived from the values of other underlying assets, such as agricultural commodities, metals, financial assets, intangible assets.
Derivative is a product whose value is derived from the value of one or more basic underlying variables. Refer to the presentation for more information on derivatives.
understanding margins for cash and derivative marketskcysrutha
Margins in stock markets help address the risk and uncertainty of share price movements. There are several types of margins for cash and futures/options markets. In cash markets, value at risk (VaR) margin covers potential losses estimated using historical volatility. Extreme loss margin covers losses outside VaR estimates. Mark-to-market margin accounts for daily price changes on open positions. In futures/options, initial margin covers maximum potential losses under different scenarios using SPAN modeling. Exposure margin covers losses from index/security price changes. Premium and assignment margins are paid on options premiums and assignments. Margin benefits can reduce requirements for offsetting positions.
Technical Trading Rules for the NASDAQ100Temi Vasco
This paper analyzes technical trading rules applied to 15 years of daily NASDAQ 100 index data. It finds that simple moving average crossover rules generated more positive returns on buy days compared to sell days, though the differences were not statistically significant. A strategy of going long the index on buy signals and holding cash on sell signals did not outperform a simple buy-and-hold strategy after accounting for transaction costs. The results suggest technical trading rules did not provide a reliable way to earn excess returns in this market over the period studied.

A derivative is a security whose price is dependent on one or more underlying assets, such as a stock or bond. It is a contract between two parties based on the performance of that asset. The value of a derivative is determined by fluctuations in the underlying asset. Derivatives allow for efficient management of financial risks and help ensure opportunities are not ignored. They provide a tool for limiting risks faced by individuals and organizations in conducting business. Effective use of derivatives can both reduce costs and increase returns.

This document defines and explains various types of derivatives such as forwards, futures, options, and swaps. It discusses how derivatives derive their value from underlying assets like stocks, bonds, currencies, and commodities. Key points covered include how derivatives work, common uses of derivatives for hedging, speculation, and arbitrage, and examples of different derivative products and markets. News snippets at the end summarize the introduction of new derivative indexes in India relating to public sector companies and infrastructure stocks, as well as a new cash-futures spread product.
The document discusses several concepts related to futures and options trading:
1) It provides the formula for determining future prices based on the spot price, risk-free rate, time to expiration, and dividends.
2) It describes different positions that can be taken in futures markets, including cash and carry arbitrage, calendar spreads, and naked spreads.
3) It lists criteria for selecting stocks that are eligible for futures and options trading, such as market capitalization, average daily trading value, and order size.
4) It defines concepts like implied volatility, VWAP, systematic and unsystematic risk, beta, hedging strategies, and open interest.
The document provides an introduction to asset pricing models and capital market theory. It discusses the assumptions and development of the Capital Asset Pricing Model (CAPM). The key assumptions include all investors having homogeneous expectations, a risk-free rate of return, and market equilibrium. The CAPM allows investors to determine the required rate of return for any risky asset based on its relationship to the market portfolio. The market portfolio contains all risky assets and has only systematic risk that cannot be diversified away. The CAPM leads investors to hold either the risk-free asset or the optimal market portfolio.
1. The document discusses various derivatives trading concepts such as futures contracts, forward contracts, and options. It explains that futures contracts are standardized agreements to buy or sell an asset at a specified price on a future date, while forward contracts are customized agreements with physical delivery of the asset.
2. Options are described as contracts that give the buyer the right but not the obligation to buy or sell an asset at a specified price on or before the expiration date. The main types are calls, which are rights to buy, and puts, which are rights to sell.
3. Participants in futures markets are identified as hedgers who protect their positions, speculators who take risks seeking profits, and arbitrageurs who exploit
This document provides an overview of options and options strategies. It discusses that options can be used to protect investments, increase income, buy equities at lower prices, and benefit from price movements without owning the underlying asset. The benefits of options include orderly markets, flexibility, leverage, and limited risk for buyers. Several strategies are then described in detail, including covered calls, married puts, bull/bear call/put spreads, protective collars, long straddles/strangles, butterfly spreads, iron condors, and iron butterflies. Each strategy is outlined in 1-2 sentences.
Portfolio Investment can be understood easily.Sonam704174
Portfolio Investment can be understood as a bunch of different financial securities (including assets, stocks, government bonds, corporate bonds, mutual funds, other money market instruments, cash and cash equivalents, cryptocurrencies, commodities, and bank certificates of deposit.), bought with an expectation to gain either in the form of return or increased value, or both.
Modern portfolio theory (MPT) is a theory of finance that aims to construct portfolios that offer the maximum expected return for a given level of risk or the minimum risk for a given level of expected return. MPT uses diversification and asset allocation to reduce portfolio risk. It assumes investors are rational and markets are efficient. MPT models asset returns as normally distributed and defines risk as standard deviation of returns. It seeks to minimize total portfolio variance by combining assets whose returns are not perfectly correlated. The efficient frontier shows the optimal risk-return tradeoff and the capital allocation line incorporates a risk-free asset into the analysis. MPT is widely used but also faces criticisms around its assumptions.
1) Futures contracts are agreements to buy or sell an asset at a predetermined price on a specified future date. Commodity futures involve agricultural and industrial goods, while financial futures are based on stock indexes, interest rates, and currencies.
2) Futures contracts are used by hedgers seeking to offset price risk and speculators hoping to profit from price changes. Clearinghouses associated with exchanges guarantee trades and regulate deliveries.
3) The theoretical futures price is determined by arbitrage and equals the current cash price plus the cost of carry until the futures contract expires. Basis risk and cross-hedging risk can reduce the effectiveness of hedging strategies using futures.
This document provides an overview of derivatives and the derivatives market in India. It begins with definitions of derivatives and describes their key characteristics, including that their value is derived from an underlying asset. It then discusses the major types of derivatives - forwards and futures - and compares their features. Forwards are customized bilateral contracts while futures are standardized exchange-traded contracts. The document also outlines the major players in the derivatives market, including hedgers, speculators, and arbitrageurs. Finally, it discusses margin requirements and daily marking to market in futures contracts to manage risk.
This document discusses portfolio theory and optimal portfolio selection using Markowitz principles. It explains that Markowitz developed the efficient frontier, which identifies efficient portfolios that offer the best risk-return tradeoff from a given set of assets. To select optimal portfolios, investors should identify the efficient frontier using expected returns, variances and covariances of the assets, then choose portfolios based on their risk tolerance along the efficient frontier. The asset allocation decision, which determines the weighting between different asset classes, is the most important investment decision according to portfolio theory.
Hedging is an investment strategy employed to reduce risk from market fluctuations. It involves taking offsetting positions, such as holding securities that move inversely to other investments in a portfolio. The goal of hedging is to limit losses without significantly reducing potential gains. Common hedging instruments include futures, options, and diversifying asset types. While hedging reduces risk, it provides no guarantee and perfect hedges are difficult to achieve.

Mf0010 – security analysis and portfolio managementak007420
The document provides information on investment characteristics, distinguishing between investment and speculation. It discusses risk and how it is measured, outlining factors like business risk, inflation risk, and market risk. It compares fundamental analysis, which examines financial statements and economic factors, to technical analysis, which studies price charts and trends. Fundamental analysis takes a longer-term view while technical analysis has a shorter timeframe. The document also outlines the assumptions of the Capital Asset Pricing Model and some of its limitations.
This document provides an overview of an upcoming presentation on asset pricing models. The presentation will cover capital market theory, the capital market line, security market line, capital asset pricing model, and diversification. It will discuss the assumptions and formulas for the capital market line and security market line. The capital market line shows expected returns based on portfolio risk, while the security market line shows expected individual asset returns based on systematic risk. The capital asset pricing model uses the concept of beta to calculate the expected return of an asset based on its risk relative to the market.
The document discusses Harry Markowitz's model for portfolio selection and William Sharpe's Single Index Model. Markowitz developed the Mean-Variance model in 1952 to select portfolios that reduce risk by diversifying across assets with low covariance. Sharpe later extended this with the Single Index Model, which assumes returns are explained by just one market factor. The document also outlines the assumptions, parameters, efficient frontier, and criticisms of both models.
The variance swap market has grown exponentially over the past decade and is among the most liquid equity derivatives contracts. Variance swaps provide exposure to volatility through the difference between the implied and realized variance of an underlying asset. Historically, the implied volatility of indices has been higher than realized volatility, allowing those taking short volatility positions to profit. Standard and Poor's has developed indices to benchmark volatility arbitrage strategies, such as the S&P 500 Volatility Arbitrage Index which measures the performance of a variance swap on the S&P 500.
The document discusses various methods of hedging risks with derivative securities. It covers topics like contracts (spot, forward, futures), options (calls, puts), risks associated with futures, forwards and options (contingent credit risk), and compares different hedging methods like writing vs buying options, futures vs options hedging, and swaps vs forwards/futures/options. The document is presented by various members and each member covers a specific topic related to derivative securities and hedging risks.

OJP data from firms like Vicinity Jobs have emerged as a complement to traditional sources of labour demand data, such as the Job Vacancy and Wages Survey (JVWS). Ibrahim Abuallail, PhD Candidate, University of Ottawa, presented research relating to bias in OJPs and a proposed approach to effectively adjust OJP data to complement existing official data (such as from the JVWS) and improve the measurement of labour demand.
In a tight labour market, job-seekers gain bargaining power and leverage it into greater job quality—at least, that’s the conventional wisdom.
Michael, LMIC Economist, presented findings that reveal a weakened relationship between labour market tightness and job quality indicators following the pandemic. Labour market tightness coincided with growth in real wages for only a portion of workers: those in low-wage jobs requiring little education. Several factors—including labour market composition, worker and employer behaviour, and labour market practices—have contributed to the absence of worker benefits. These will be investigated further in future work.

"Does Foreign Direct Investment Negatively Affect Preservation of Culture in the Global South? Case Studies in Thailand and Cambodia."
Do elements of globalization, such as Foreign Direct Investment (FDI), negatively affect the ability of countries in the Global South to preserve their culture? This research aims to answer this question by employing a cross-sectional comparative case study analysis utilizing methods of difference. Thailand and Cambodia are compared as they are in the same region and have a similar culture. The metric of difference between Thailand and Cambodia is their ability to preserve their culture. This ability is operationalized by their respective attitudes towards FDI; Thailand imposes stringent regulations and limitations on FDI while Cambodia does not hesitate to accept most FDI and imposes fewer limitations. The evidence from this study suggests that FDI from globally influential countries with high gross domestic products (GDPs) (e.g. China, U.S.) challenges the ability of countries with lower GDPs (e.g. Cambodia) to protect their culture. Furthermore, the ability, or lack thereof, of the receiving countries to protect their culture is amplified by the existence and implementation of restrictive FDI policies imposed by their governments.
My study abroad in Bali, Indonesia, inspired this research topic as I noticed how globalization is changing the culture of its people. I learned their language and way of life which helped me understand the beauty and importance of cultural preservation. I believe we could all benefit from learning new perspectives as they could help us ideate solutions to contemporary issues and empathize with others.

Decoding job postings: Improving accessibility for neurodivergent job seekers
Improving the quality and accessibility of job postings is one way to reduce employment barriers for neurodivergent people.
A toxic combination of 15 years of low growth, and four decades of high inequality, has left Britain poorer and falling behind its peers. Productivity growth is weak and public investment is low, while wages today are no higher than they were before the financial crisis. Britain needs a new economic strategy to lift itself out of stagnation.
Scotland is in many ways a microcosm of this challenge. It has become a hub for creative industries, is home to several world-class universities and a thriving community of businesses – strengths that need to be harness and leveraged. But it also has high levels of deprivation, with homelessness reaching a record high and nearly half a million people living in very deep poverty last year. Scotland won’t be truly thriving unless it finds ways to ensure that all its inhabitants benefit from growth and investment. This is the central challenge facing policy makers both in Holyrood and Westminster.
What should a new national economic strategy for Scotland include? What would the pursuit of stronger economic growth mean for local, national and UK-wide policy makers? How will economic change affect the jobs we do, the places we live and the businesses we work for? And what are the prospects for cities like Glasgow, and nations like Scotland, in rising to these challenges?

Fabular Frames and the Four Ratio ProblemMajid Iqbal
Digital, interactive art showing the struggle of a society in providing for its present population while also saving planetary resources for future generations. Spread across several frames, the art is actually the rendering of real and speculative data. The stereographic projections change shape in response to prompts and provocations. Visitors interact with the model through speculative statements about how to increase savings across communities, regions, ecosystems and environments. Their fabulations combined with random noise, i.e. factors beyond control, have a dramatic effect on the societal transition. Things get better. Things get worse. The aim is to give visitors a new grasp and feel of the ongoing struggles in democracies around the world.
Stunning art in the small multiples format brings out the spatiotemporal nature of societal transitions, against backdrop issues such as energy, housing, waste, farmland and forest. In each frame we see hopeful and frightful interplays between spending and saving. Problems emerge when one of the two parts of the existential anaglyph rapidly shrinks like Arctic ice, as factors cross thresholds. Ecological wealth and intergenerational equity areFour at stake. Not enough spending could mean economic stress, social unrest and political conflict. Not enough saving and there will be climate breakdown and ‘bankruptcy’. So where does speculative design start and the gambling and betting end? Behind each fabular frame is a four ratio problem. Each ratio reflects the level of sacrifice and self-restraint a society is willing to accept, against promises of prosperity and freedom. Some values seem to stabilise a frame while others cause collapse. Get the ratios right and we can have it all. Get them wrong and things get more desperate.

STRUCTURED MARKETS
4. 4
1.ABSTRACT
Structured Markets is so titled because it attempts to research the structure of both
the derivative markets and insurance principles, to consider, hypothesize, and
discuss alternative measures of consideration that can be taken by investors with
respect to loss and risk distributions.
We begin with an introduction to the financial derivatives markets, followed by
general option positions and strategies. We expand on the topic of option markets,
and explain their use in the context of risk management and where they may differ
from insurance. We consider various financial instruments such as forwards,
futures, swaps, and discuss how these instruments are constructed, with respect to
global financial markets, commodities, currencies, and interest rates. Finally, we
examine and discuss insurance features such as premiums, and deductibles, and
explain their relevancy to investments, and asset liability management. We
conclude the paper with some general remarks on risk assumptions and classes.
Our discussions are theoretically relevant to various different industries and can
therefore be thought of as all-inclusive. For the purposes of our discussion, we
refrain from choosing some specific industry, or asset portfolio, since this would
not affect any measure of pertinence, and would differ only with regard to
circumstantial applicability. An industry varies from another only with respect to
its particular key performance indicator(s) and its inherent nature(s) of risk; but
remains identically equivalent with respect to the constitution of the strategic
factors involved in its data analytics and performance.

1.1 An Introduction To Derivatives
Financial instruments are the essential backbones of all financial institutions, and
among these financial instruments are the derivative markets. Derivative markets
can include, but are not limited to, puts, call, forwards, futures, options, and swaps.
These instruments have numerous characteristics, including their financial
structure, and how they can be used to strategically implement procedures for
financial optimization. There can be many advantages to investing in derivatives as
opposed to investing in outright ownership of a specific asset or index, including
tax reductions, and lower transaction costs.
Clearly, there may be numerous differences between investing in derivatives and
investing in an underlying asset. One such distinction is that investing in
derivatives is generally a less costly investment, being that it can only be exercised
at a particular performance indicator, and in many cases, actually expire
unexercised.
Another distinction is that an investor who holds a position in derivatives is
generally concerned with optimizing his or her strategies and hedging techniques,
and can therefore becomes more fixated on long term and out of the money
positions. An investor in assets or indexes, on the other hand, may be more focused
on day to day trading, and in the money action. This is an important distinction.
Because derivatives are more heavily involved in positions that lie outside the
money, they also afford their investors the time to be able to change a position, and
thereby dramatically defer the risk exposure of these assets.

2.OPTION POSITIONS AND STRATEGIES
We begin our paper by describing the structures of the fundamental financial
instruments that make up the derivative markets, and various positions and
strategies that option holders can choose to take.
2.1 Puts, Calls, and Forwards
A call is defined as the right to buy a specified number of shares of an underlying
asset at expiration. The payoff for a call is
Max [𝐒 𝐓 -X,0]
however the profit is
Max [𝐒 𝐓 -X,0]- [FV of premium]
since there is a premium paid for the call.
A put is defined as the right to sell a specified number of shares of an underlying
asset at expiration. The payoff for a put is
Max [X -𝐒 𝐓,0]
however the profit is
Max [X -𝐒 𝐓,0]- [FV of premium]
since there is a premium paid for the put.
7. 7
A seller of these derivatives would have the corresponding negative payoffs and
profits for both of these positions, and would be expressed as
-{Max [𝐒 𝐓 -X,0]}
-{Max [𝐒 𝐓-X,0]- [FV of premium]}
-{Max [X -𝐒 𝐓,0]}
-{Max [X -𝐒 𝐓,0]- [FV of premium]}
for calls and puts respectively.
Forwards are defined as an agreement to the purchase of an asset at a later point
in time at an agreed upon price and have equal profits and payoffs which are
𝐒 𝐓 − 𝐅𝟎,𝐓
for a long position in the forward, and
𝐅𝟎,𝐓 − 𝐒 𝐓
8. 8
for a short position in the forward. We will have more to say about forwards later.
2.2 Insurance, Hedging, and Option Strategies
We will proceed with some examples of option strategies that have insurance and
risk management features which are created using calls, puts, and forwards, and
underlying assets.
Synthetic forward: A long synthetic forward can be created through a long call
together with a short put since
Max [𝐒 𝐓 -X,0] + -{Max [X -𝐒 𝐓,0]}= 𝐒 𝐓 - 𝐅𝟎,𝐓
and similarly a short synthetic forward can be created through a short call together
with a long put since
-{Max [𝐒 𝐓 -X,0]} + Max [X -𝐒 𝐓,0] = 𝐅𝟎,𝐓 − 𝐒 𝐓
Covered Call: This position can be created by buying an asset in order to protect
against the sale of a call, and resembles the sale of a put since
-{Max [𝐒 𝐓 -X,0]} + 𝐒 𝐓 = -{Max [X -𝐒 𝐓,0]}
Covered Put: This position can be created by selling an asset in order to protect
against the sale of a put, and resembles the sale of a call since
9. 9
-{Max [X -𝐒 𝐓,0]} – S = -{Max [𝐒 𝐓 -X,0]}
Straddle1
: This position consists of the purchase of a call and a put at the same
strike price and is entered into in order to profit from any movement in the price of
the stock.
Strangle: This position consists of the purchase of a call and a put where the call is
at a greater strike price than the put and is entered into in order to profit from large
movement in the price of the stock.
Collar: This position consists of the purchase of a put and the sale of a call where
the put is at a lower strike price than the put, and is entered if one believes that the
stock will either remain near the current price or go down, but not go up.
Box Spread: This position consists of a combination of a synthetic long forward,
and a synthetic short forward, or regular long and short forward, at the same strike.
Bull Spread: This can be created either with a long call and a short call where the
long call is at a lower strike price, and the short call is at a higher strike price, or
through a long put and a short put where the long put is at a lower strike price, and
the short put is at the higher strike price.
Bear Spread: This can be created either with a long call and a short call where the
long call is at a higher strike price, and the short call is at a lower strike price, or
through a long put and a short put where the long put is at a higher strike price, and
the short put is at the lower strike price.
Butterfly: This can be created either with a long call at a low strike price, 2 short
calls at a higher strike price, and a long call at an even higher strike price.

Note that we do not explicitly provide formulas for the following 7 option strategies, as they are merely
combined option positions. The reader should also note that all of these positions can be written/sold, and
thus reversed.
10. 10
Alternatively, this is created with a long put at a low strike price, 2 short puts at a
higher strike price, and a long put at an even higher strike price.
Occasionally, investors also engage in what is known as cross hedging2
which
entails hedging an asset that is highly correlated with the underlying asset, but is
still not identical to it.
2.3 An Introduction to Risk Management
The position of an insurer to meet its liabilities in the events of peril(s) is most
similar to an option market position of a short put. The insurance company
guarantees payment to the insured for losses below a predetermined loss amount.
As the price of the loss increases, the price of the asset decreases, and the insurance
company’s payout increases. Profits for the insurance company are only realized in
the event that the total payout to the pool of insured parties does not exceed a
certain calculated amount. The insurance company profits by receiving the amount
of the premium paid by the insured, and in doing so obligates itself to undertake
some risk that can be potentially associated with some underlying asset.
The position of the insured in an insurance contract is most similar to that of
someone who has a long position on some underlying asset, where he or she can
either gain from an increase in value of the asset or lose from a decrease in value to
the asset. The insured will enter into a contract with the insurance company in
order to be protected from the financial uncertainty and risk that would result in a
decrease in value to the underlying asset and in doing so, is essentially entering
into a position that is most similar to that of a long put. A notable point of
comparison, therefore, between the writer of a put and that of an insurer is that
2
See Burnrud (pp.490) for an elaborate discussion on the topic of cross hedging.
11. 11
neither of them will gain as the asset increases; they are affected and face exposure
to risk solely by decreases in the prices of the asset. Consequently, any insurance
company is interested to estimate the probability distributions of the potential loss
amounts of the underlying asset and how they may compare to the probability
distributions of the expected payout for any policy that they may market, in order
to be able to correctly calculate and manage its exposure to risk.
There are additional factors that should be of primary concern and considerations
to investors, even in the option market. Consider for example what an investor
should do if the possibility of an asset increasing or decreasing is not monotonous,
but that for some increase we anticipate that it will do so according to some
particular distribution.
Another example for an investor to consider when managing risk is if an analysis
predicts some estimation that for a company there is a likelihood that the price will
go in some particular direction, yet the investor is willing to pay some minimal
amount if the stock price doesn’t move a certain amount. This would resemble the
structure of an insurance deductible. We will discuss this topic in Chapter 5.
In these types of scenarios, using Calls, Puts, and the simple strategies that we
have mentioned, or variations thereof, would seem to be inadequate, as they do not
allow for the aforementioned adjustments and do not lend themselves towards any
increased revenue for general models of loss distributions. Such possibilities
should be at the forefront of an investors strategy to manage risk.
12. 12
3.FORWARDS, FUTURES, AND SWAPS
We begin to explain the properties of forwards, and their relationship to other
types of both similar and non-similar financial instruments.
3.1 Financial Forwards And Futures
In general there are four ways in which a stock, or any asset, can be purchased:
3.1.1 Outright Purchase
The buyer pays for the stock up front and also receives the stock.
The price of this is quite obviously the current price of the stock (S!).
3.1.2 Fully Leveraged Purchase
The buyer pays at a later time but receives the stock up front. Because the buyer
is essentially borrowing the security until Time T the price of this is the Stock price
multiplied by the continuously compounded rate denoted
𝐒 𝟎 ∗ 𝐞 𝐫𝐓
.
3.1.3 Prepaid Forward Contract
The buyer pays up front but receives the stock at a later time. In this case we have
to differentiate between if there are no dividends to where there are dividends. In
the former case the buyer is in essence giving nothing extra to the seller by paying
early and allowing the seller to hold on to the stock since no additional value is
perceived to belong to the owner of the stock the stock at during the interval form
13. 13
Time 0 to Time T. Even assuming that the return on the stock will be some
calculated return, denoted (α), we then discount this return to Time 0 and are left
with the original price of the Stock, because,
𝐒 𝟎 ∗ 𝐞 𝛂𝐓
∗ 𝐞!𝛂𝐓
= 𝐒 𝟎.
Thus the price of the Prepaid Forward will be the same as the current stock Price,
or
𝐅𝟎,𝐓
𝐏
= 𝐒 𝟎.
Additionally, since if the price of one was greater than the other one could easily
construct a portfolio which contains arbitrage, buy buying the one that is lower,
and selling the one that is higher.
In the scenario where there are dividends on the stock that is being purchased
under a prepaid forward contract, however, the above logic does not hold true. In
this case, the buyer should be paying less than the Stock Price. Because he is only
receiving the stock at a later date, he is not receiving the dividends that are paid
during that interim, and thus the value of the stock to the buyer is decreased by the
amount of the value of those dividends.
In the case of discrete dividends, the value of the Prepaid Forward can therefore
be written as
14. 14
𝐅𝟎,𝐓
𝐏
= 𝐒 𝟎 – 𝐃𝐢𝐯 ∗ 𝐞!𝐫𝐢𝐧
𝐢!𝟎 .
In the case of continuous dividends, where δ is the continuous dividend yield
from that particular index, this can be written as
𝐅𝟎,𝐓
𝐏
= 𝐒 𝟎*𝐞!𝛅𝐓
.
In both of these cases the value of the Prepaid Forward is calculated as the stock
price deducted by the amount of the dividends that the buyer of the Prepaid
Forward is forgoing by receiving the stock at time T.
3.1.4 Forward Contract
The buyer pays at a later time and the buyer receives the stick at al a later time.
Essentially, this is the exact same thing as the Prepaid Forward Contract except
that the payment is made at Time T, and therefore we can calculate the price of a
Forward by simply calculating the Future value of the Prepaid Forward Contract.
Thus,
𝐅𝟎,𝐓 = 𝐅𝟎,𝐓
𝐏
𝐞 𝐫𝐓
and since
𝐅𝟎,𝐓
𝐏
= 𝐒 𝟎*𝐞!𝛅𝐓
15. 15
we can rewrite
𝐅𝟎.𝐓 = 𝐅𝟎,𝐓
𝐏
𝐞 𝐫𝐓
as
𝐅𝟎,𝐓 =𝐒 𝟎*𝐞!𝛅𝐓
*𝐞 𝐫𝐓
= 𝐒 𝟎*𝐞(𝐫!𝛅)𝐓
Therefore there are two equivalent equations that we can use to calculate the Price
of a Forward Contract:
𝐅𝟎,𝐓 = 𝐅𝟎,𝐓
𝐏
𝐞 𝐫𝐓
= 𝐒 𝟎 𝐞(𝐫!𝛅)𝐓
We can therefore understand the configuration of a synthetic forward. In order to
duplicate the structure of the long forward which has a payoff of
𝐒 𝐓 - 𝐅𝟎,𝐓
16. 16
we create the same payoff by borrowing
𝐒 𝟎 𝐞!𝛅𝐓
and using the borrowed funds to buy an index in the stock. Then at time T the
borrower has to pay back
𝐒 𝟎 𝐞(𝐫!𝛅)𝐓
but keeps the amount of the stock, ( S!), so that his net total will be
𝐒 𝐓 − 𝐒 𝟎 𝐞(𝐫!𝛅)𝐓
= 𝐒 𝐓 - 𝐅𝟎,𝐓
This formula provides the ability and understanding that one can do what is
known as asset allocation which means that if one believes that the index that is
held may go down, rather than sell the position on the index, one can keep the
stock and short the forward. Because
17. 17
𝐅𝟎,𝐓 = 𝐒 𝟎 𝐞(𝐫!𝛅)𝐓
if the risk free-rate (r) is for example 10%, and the stock price (S!) is 100, then the
forward price (F!,! )will be 110. Thus if for example we are unsure of the future of
the stock and assume that if it goes up it will go up to 140, and if it goes down, it
will go down to 70, by entering into a short forward, we are guaranteed to be
earning 110. If the stock increases to 140, we gain 40 from the stock gain, but lose
(110-140 = -30) from the short forward so that our net return is 40 – 30 =10.
Should the stock go down to 70 we will lose 30 from the ownership of the stock,
but earn (110 – 70 = 40) from the short forward, so that again our net position is
40-30=10.
3.2 Currency Forwards And Futures
These considerations lead to a parallel calculation for what are known as currency
Forwards and Futures. The purpose of writing these contracts is in order to manage
risk exposure to future changes in currency exchange rates. This is particularly
important for importers of foreign goods. The importer may want to guarantee a
foreign manufacturer a forward price denominated in the exporter’s currency, but
wants to know that he is insured against a decrease in the exchange rate. He can
therefore enter into a Currency Forward.
We first denote X as the local currency, and Y as the foreign currency and 𝑅! and
𝑅! as the rates of these respective locations. Let us further denote 𝑍! as the
exchange rate of the two currencies as of time 0. In order to have Y = 1 at time 1
we need 𝑒!!! at time 0. For this we will need an amount in the local currency (X)
of 𝑍! 𝑒!!!. This will be the price of the prepaid forward which guarantees that we
18. 18
have this amount of foreign currency at time T. We can thus write the following
equation for the prepaid forward:
𝐅𝟎,𝐓
𝐏
= 𝒁 𝟎 𝒆!𝑻𝑹 𝒚
Because the importer is giving money towards this contract at time 0 he is
forfeiting otherwise possible interest gains. The formula reflects this loss just as in
the parallel stock equivalent the formula reflects an absence of the stock dividends
that the buyer of the prepaid forward is forfeiting.
We can also use this information to calculate the forward price of such a contract
by calculating the future value of the prepaid forward since as we have seen in the
case of a stock,
𝐅𝟎,𝐓 = 𝐅𝟎,𝐓
𝐏
𝐞 𝐫𝐓
= 𝐒 𝟎 𝐞(𝐫!𝛅)𝐓
Thus here as well,
𝐅𝟎.𝐓 = 𝐅𝟎,𝐓
𝐏
𝐞 𝐫𝐓
= 𝒁 𝟎 𝒆 𝑹 𝒙!𝑹 𝒚 𝑻
It is interesting to note that whenever
𝑹 𝒙 > 𝑹 𝒚
the forward currency price (F!.!) will be greater than the exchange rate (Z).
19. 19
This leads to an important point. Namely that such a position can be constructed
synthetically by borrowing in one currency and lending in another. So if we want
to have 1 unit in a foreign currency in 1 year we have to invest
𝒁 𝟎 𝒆!𝑹 𝒚
which is a dollar (domestic) amount. We can borrow this amount and have to repay
the amount of
𝒁 𝟎 𝒆 𝑹 𝒙!𝑹 𝒚 𝑻
the forward exchange rate, at time T. So we see that borrowing and lending in
different currencies is the same cash flow as a forward contract.
3.3 Euro Dollar Futures
Euro Dollar Futures are contracts that are written on a deposit that is already
earning a rate such as LIBOR. First the initial LIBOR Rate is by convention
annualized. So if the current quarterly rate on LIBOR is 2%, the annualized rate is
8%. Any increase in the LIBOR rate will increase the borrowing cost by the
increase rate per dollar borrowed. A Euro Dollar Contract is written as 100 minus
the LIBOR Rate. Such a contract can therefore be written to guarantee a borrowed
rate of say 3% at a price of 97 dollars.
The way that this contract can be used would be to protect against interest rate
risk as follows: If we enter a into a LIBOR contract to borrow in 6 months at an
annualized rate of 3% the Euro Dollar futures contract will cost currently
[100-5(Current LIBOR)] =95.
20. 20
6 months later if the LIBOR Rate has increased to 5% our borrowing expense will
have risen [5-3] = 2. However by simultaneously having entered into a short Euro
Dollar Futures Contract which will then be at [100-5(Current LIBOR)] = 95 so that
we will now gain the difference of the Euro Dollar Futures contract as [97-95] = 2.
In a similar way, these positions can of course be reversed by going long in the
Euro Dollar Futures.
3.4 Commodity Forwards And Futures
Essentially commodity forwards and futures reflect those of financial forwards
and therefore their pricing resembles them. If the discount factor for the
commodity is 𝛽, the price of the prepaid forward will be
𝐅𝟎,𝐓
𝐏
= 𝒆!𝜷𝑻
* E[S]
where E[S] is the expected spot price at time t, and therefore its forward price is
𝐅𝟎.𝐓 = 𝐅𝟎,𝐓
𝐏
𝐞 𝐫𝐓
= 𝐄[𝐒]𝐞!(𝜷!𝐫)𝐓
just as with financial forwards.
There are two main differences to note when calculating the forward price of a
commodity. Firstly an adjustment must be made for the storage of the commodity
(which we can denote as s). Storage is an unavoidable cost and cannot be ignored.3
3
See McDonald (pp. 202) who defines this cost as a ‘lease rate’ and explains it in terms of discounted cash flows by
letting some variable be the equilibrium discount rate for an asset with the same risk as the commodity.
21. 21
An additional adjustment must be made to the price for what is known as a
convenience yield, which is defined as a non monetary return that the holder of the
commodity gains by merely having physical possession of the commodity. This
possession gives its owner the insurance that in the event that the price of the
commodity rises he will remain unaffected, and it will not disturb his business
cycle although he may be largely reliant on the commodity. The convenience yield
(which we can denote as c) that is gained must also be calculated into the price of
the forward on the commodity so that the ending forward price for a commodity
should be
𝐅𝟎.𝐓 = 𝐒 𝟎 𝐞(𝐫!𝐜!𝐬)𝐓
,
which denotes the total cost to the buyer of the commodity as a reflection of his
paying for the future value of the commodity, including the interest rate, and the
storage cost, less the amount of the convenience yield. This is largely applicable
when wishing to calculate an entire production for a commodity. To do so, we
simply sum the respective forward rates over each period, while compensating for
any additional cost per unit of the commodity and any other initial investments or
fixed costs. If we suppose that, for example ,at each time 𝑡!, where x goes from
1,2…n, we expect to produce 𝑛𝑡! units of the commodity, we can then calculate
the total Net Present Value for the commodity held operation as
𝒏𝒕 𝒙 𝐅𝟎.𝐓 𝒙
− 𝑴𝒈 𝒕 𝒙 𝒆!𝒓 𝟎,𝒕 𝒙 𝒕 𝒙
𝒏
𝒙!𝟏
– 𝑪
22. 22
where Mg is the Marginal cost per unit of the commodity that is produced, and C is
the fixed cost of the project. More complicated adjustments for specific
commodities do arise as may be necessary for commodities in the energy market
such as oil, electricity, and natural gas. Although these specific adjustments are
beyond the scope of this paper, we note this so that the reader may be aware that
each commodity may differ with respect to its particular circumstance(s).
3.5 Interest Rate Forwards And Futures
For zero-coupon bonds the price of the bond is the Present Value of the
Redemption Value, which is defined as
𝑷𝒓𝒊𝒄𝒆 = 𝑪𝒆!𝜹𝒕
,
where 𝐶 is the redemption value, and 𝛿 is the continuously compounded rate.
This is particularly useful when we observe the price, and want to calculate the
corresponding yield. The yield is then (where 𝐶 is 1), just
𝜹 = 𝐥𝐧
𝟏
𝑷𝒓𝒊𝒄𝒆
∗ (
𝟏
𝒕
) .
What is relevant to our discussion is how forward and futures contracts could be
used to protect against changes in the interest rate. These contracts are known as an
FRA, or Forward Rate Agreement, and are written to give a borrower a previously
23. 23
agreed upon rate on a loan regardless of changes in the interest rate. The agreed
upon rate is the implied forward rate. When the actual rate at the time the FRA is
settled, the parties must calculate the difference between the actual rate and the
implied forward rate and the borrower must pay the difference times the principal
amount that is borrowed, which may be positive or negative depending on whether
the interest rate is higher or lower than the implied forward rate that was agreed
upon. The overall agreement for the FRA is thus
(𝒓 𝒓𝒆𝒂𝒍 𝒓𝒂𝒕𝒆 𝒐𝒇 𝒊𝒏𝒕𝒆𝒓𝒆𝒔𝒕 − 𝒓 𝑭𝑹𝑨 𝒓𝒂𝒕𝒆) ∗ 𝑳
where L is the principal loan amount that is borrowed.
Note that the above is under the assumption that the FRA is settled at the time of
the loan repayment. In the event that the FRA is settled at the time of borrowing of
the funds this amount the borrower would then only be obliged to pay the Present
Value of that amount so that the overall payment for the FRA is
(𝒓 𝒓𝒆𝒂𝒍 𝒓𝒂𝒕𝒆 𝒐𝒇 𝒊𝒏𝒕𝒆𝒓𝒆𝒔𝒕 − 𝒓 𝑭𝑹𝑨 𝒓𝒂𝒕𝒆) ∗ 𝑳
(1 + 𝒓 𝒓𝒆𝒂𝒍 𝒓𝒂𝒕𝒆 𝒐𝒇 𝒊𝒏𝒕𝒆𝒓𝒆𝒔𝒕)
24. 24
3.6 Commodity and Interest Rate Swaps
The definition of a swap is a contract that stipulates an exchange of fixed
payments, in exchange for a floating or variable set of payments, and thus can be
an additional strategy that is used to hedge against potential risk inherent in
variability. A swap is a calculated by setting the present value of the variable
payments equal to the present value of a correspondingly fixed set of payments.
The variable that will satisfy the equation of value for the fixed payment would
become the new payment that the buyer of the swap would be responsible to pay
per payment period. Since we would normally calculate the sum of all present
values of numerous forward contracts as
𝑵𝑷𝑽 =
𝑭 𝟎,𝟏
𝟏 + 𝒊 𝒕𝟏
+
𝑭 𝟏,𝟐
𝟏 + 𝒊 𝒕𝟐
+ ⋯
𝑭 𝒕(𝒏!𝟏),𝒕𝒏
𝟏 + 𝒊 𝒕𝒏
to calculate the swap rate we would similarly calculate a rate which satisfies the
value of x for
𝑵𝑷𝑽 =
𝒙
𝟏 + 𝒊 𝒕𝟏
+
𝒙
𝟏 + 𝒊 𝒕𝟐
+ ⋯ .
𝒙
𝟏 + 𝒊 𝒕𝒏
In contrast to a forward contract, which calls for different payments at time 𝑇! and
time 𝑇! …, the payments of a swap are fixed and in fact identical.
25. 25
Ultimately,
𝑵𝑷𝑽 =
𝑭 𝟎,𝟏
𝟏 + 𝒊 𝒕𝟏
+
𝑭 𝟏,𝟐
𝟏 + 𝒊 𝒕𝟐
+ ⋯
𝑭 𝒕(𝒏!𝟏),𝒕𝒏
𝟏 + 𝒊 𝒕𝒏
=
𝒙
𝟏 + 𝒊 𝒕𝟏
+
𝒙
𝟏 + 𝒊 𝒕𝟐
+ ⋯ .
𝒙
𝟏 + 𝒊 𝒕𝒏
Swaps can be entered into for commodities and also for interest rate arrangements
in which one party wishes to lock in a particular rate. These will create a fixed rate
for debt instead of an otherwise potentially volatile floating rate debt.
In order to present value the forward rates, these forward rates themselves must
first be calculated. Because these forward rates are an unknown at time 0 we must
calculate them by using the current spot rate to determine what the implied forward
rate for a particular year is. Since in general,
(𝟏 + 𝑺 𝟏)(𝟏 + 𝑭 𝟎,𝟏) = (𝟏 + 𝑺 𝟐) 𝟐
the implied forward rate for year 1 can be calculated as
(𝟏 + 𝑭 𝟎,𝟏) =
(𝟏 + 𝑺 𝟐) 𝟐
(𝟏 + 𝑺 𝟏)
26. 26
This can be repeated to solve for the implied forward rate of any future particular
year by calculating that forward rate as
(𝟏 + 𝑭 𝒏!𝟐,𝒏!𝟏) =
(𝟏 + 𝑺 𝟐) 𝒏
(𝟏 + 𝑺 𝟏) 𝒏!𝟏
Subsequently, these implied forward rates, are discounted by present valuing them
all to time 0, by their respective present value interest rates4
.
A significant and noteworthy feature of an interest rate swap is that its cash flows
are in fact identical to buying a bond where there is a fixed stream of payments,
and a redemption payment is made at the time that the bond is redeemed. This is
because the party entering the interest rate swap, by definition, has an outstanding
loan and is now due to make a fixed stream of payments to pay back the loan, in
addition to repayment of the principal at the time that the loan is due. All the future
identical cash flows of a bond are valued by taking the present value of each one at
its respective time of payout and discounting it back to time 0 at its particular rate
of interest. The interest rate swap thus has the same dimensions as that of a bond
whose present value is calculated as
𝑷 = 𝑭𝒓 𝒂 𝒏 + 𝑪𝒗 𝒏
4
Also see Flavell (pp.140) for a discussion on Longevity swaps which at the time written had been under
discussion for some 5 years. The two sides of such a structure would typically be: . . pay an income
stream based upon current longevity expectations; receive an income stream, usually based upon changes
in one of the OTC indices.
27. 27
In both of these cases a stream of identical cash flows are discounted at some rate
to time 0, in order to appropriately calculate the total Net Present Value.5
This concept is also particularly relevant to the actual calculation of spot rates from
zero coupon bond rates or vice-versa, since in general,
[𝒁𝒆𝒓𝒐 𝑪𝒐𝒖𝒑𝒐𝒏 𝑩𝒐𝒏𝒅 𝑷𝒓𝒊𝒄𝒆] 𝒏 =
𝟏
(𝟏 + 𝑺 𝒏) 𝒏
5
Technically we have to differentiate between a par swap and a forward start swap. Hunt (pp. 231),
discusses the distinction between them as follows: ”Swaps are usually entered at zero initial cost to both
counterparties. A swap with this property is called a par swap, and the value of the fixed rate K for which
the swap has zero value is called the par swap rate. In the case when the swap start date is spot (i.e. the
swap starts immediately), this is often abbreviated to just the swap rate, and it is these par swap rates that
are quoted on trading screens in the financial markets. A swap for which the start date is not spot is,
naturally enough, referred to as a forward start swap, and the corresponding par swap rate is the forward
swap rate. Forward start swaps are less common than spot start swaps and forward swap rates are not
quoted as standard on market screens.”

4.OPTION THEORIES AND PRICING MODELS
We now begin to explain and show some of the underlying theories, structures, and
pricing models, within the derivative markets.
4.1 Parity
The definition of Put-Call Parity is
𝑪 − 𝑷 = (𝐅𝟎.𝐓 − 𝑲)𝒆!𝒓𝑻
This formula is best understood in the context of a synthetic forward constructed
through the purchase of a call and writing of a put. For any synthetic forward that
is created at a price that is lower than the forward price there is an intrinsic gain of
not having to pay the forward price and instead buying the asset, albeit
synthetically, at a lower price. There must therefore be a corresponding
requirement that the difference between the call and put in this transaction be
exactly equal to the present value of the difference between the forward rate and
the strike price. This philosophy, which is predicated on a no-arbitrage tolerance, is
the basis for the Put-Call Parity formula. We can compare the payoff diagrams of a
long forward and a long asset as follows:
29. 29
We notice that the payoff of the long stock is higher than the payoff of the long
forward for all S(T). To create a synthetic long forward that has the same payoff as
the true long forward, we need to bring the payoff of the long stock down which
can be done by selling a bond, as illustrated in the following graph.

Obviously, Put-Call Parity can also be rewritten as
𝑪 − 𝑷 = 𝐅𝟎,𝐓
𝐏
− 𝑲𝒆!𝒓𝑻
since

Similarly, we can write
𝑪 − 𝑷 = 𝐒 𝟎 − 𝑲𝒆!𝒓𝑻
where the stock is a non-dividend paying stock, since
𝐅𝟎,𝐓
𝐏
= 𝐒 𝟎
and
𝑪 − 𝑷 = 𝐒 𝟎 – 𝐃𝐢𝐯 ∗ 𝐞!𝐫𝐢𝐧
𝐢!𝟎 − 𝑲𝒆!𝒓𝑻
and
𝑪 − 𝑷 = 𝐒 𝟎*𝐞!𝛅𝐓
− 𝑲𝒆!𝒓𝑻
for stocks with discrete and continuous dividend payments respectively,
since
32. 32
𝐅𝟎,𝐓
𝐏
= 𝐒 𝟎 – 𝐃𝐢𝐯 ∗ 𝐞!𝐫𝐢𝐧
𝐢!𝟎
and
𝐅𝟎,𝐓
𝐏
= 𝐒 𝟎*𝐞!𝛅𝐓
.
The formula for Put-Call Parity also proves that a call is identical to a long position
in an asset, with a purchased put as insurance for the position when the price goes
down since
𝑪 = 𝐒 𝟎 − 𝑲𝒆!𝒓𝑻
+ 𝑷
and that a put is identical to a short position in an asset with a purchased call as
insurance for the position when the price rises since
𝑷 = 𝐂 − (𝐒 𝟎 − 𝑲𝒆!𝒓𝑻
)
Put-Call Parity also allows us to create a synthetic stock by replicating the stock
and thus mimicking its exact cash flows, and performance, since
𝑪 − 𝑷 = 𝐒 𝟎 – 𝐃𝐢𝐯 ∗ 𝐞!𝐫𝐢𝐧
𝐢!𝟎 − 𝑲𝒆!𝒓𝑻
33. 33
therefore,
𝐒 𝟎 = 𝑪 − 𝑷 + 𝐃𝐢𝐯 ∗ 𝐞!𝐫𝐢𝐧
𝐢!𝟎 + 𝑲𝒆!𝒓𝑻
This means we can exactly replicate the stock by buying the call, selling the put,
and lending the present value of both the future dividends and the strike price.
4.2 Binomial Option Pricing
The binomial option model is a calculated approach towards pricing an option.
This model assumes a particular assumption of how the stock prices [namely 𝑆!
and 𝑆! ,where 𝑆! represents the estimated move upward in the stock price and 𝑆!
represents the estimated move downward in the stock price], will move over one or
more periods based on the historical volatility of the stock.6
What becomes
relevant to our discussion is to note that the method for computing these estimated
parameters is in fact based on the aforementioned underlying assumption that
6
This seems contrary to the approach assumed by Benth (pp.110) with regard to weather derivatives
where a classical approach is presented for pricing weather derivatives called Burn analysis, which
‘simply uses the historical distribution of the weather index/event underlying the derivative as the basis
for pricing. For example, to find a price of an option based on the HDD index in a given month, January
say, we first collect historical HDD index values from January in preceding years. Based on these records,
we generate the historical option payoffs, and simply price the option by averaging. The burn analysis
therefore corresponds to pricing by the historical expectation.'
34. 34
𝐅𝟎.𝐓 = 𝐒 𝟎 𝐞(𝐫!𝛅)𝐓
The volatility factor, which is essentially just the stock’s standard deviation can be
scaled for the particular amount of time that we are estimating a change in the
stock, since in general
𝑽𝒂𝒓 𝑿
= 𝑽𝒂𝒓
𝒙𝒊
𝒏
𝒏
𝒊!𝟏
= (
𝟏
𝒏
) 𝟐
𝑽𝒂𝒓 𝒙𝒊
𝒏
𝒊!𝟏
= (

𝒏
) 𝟐
𝑽𝒂𝒓(𝒙𝒊)
𝒏
𝒊!𝟏
= (
𝟏
𝒏
) 𝟐
𝒏𝑽𝒂𝒓[𝑿]
=
𝝈 𝟐
𝒏
so that
35. 35
𝝈 𝑿
=
𝝈 𝟐
𝒏
=
𝝈
𝒏
When analyzing historic volatility therefore we can calculate the volatility that we
expect to occur during this period as
𝝈
𝑻
= 𝝈(𝟏 𝑻)
This means that
𝝈(𝟏 𝑻) 𝑻 = 𝝈
It then becomes possible to calculate 𝑆! and 𝑆! as the forward price adjusted by the
volatility since in general
𝐅𝟎.𝐓 = 𝑺 𝑻 = 𝐒 𝟎 𝐞(𝐫!𝛅)𝐓
Consequently,
𝑺 𝒖 = 𝐅𝟎.𝐓 𝒆(𝝈(𝟏 𝑻) 𝑻)
36. 36
and
𝑺 𝒅 = 𝐅𝟎.𝐓 𝒆!(𝝈(𝟏 𝑻) 𝑻)
4.3 Lognormal Distributions for Stock Prices
In order to define and dimension the behavior of the movement of a stock we can
initially assume that returns on stocks can be of the form of a normal random
variable. Admittedly this assumption may have inefficiencies, and is in fact a
subject that can and has been disputed historically, in financial literature. In this
paper we proceed with the assumption of this parameter. The mathematical basis
and logic behind the definition of a compounded rate of return is that when as we
compound an infinite amount of times, we have
𝐥𝐢𝐦
𝒏→!
𝟏 +
𝒓
𝒏
𝒏
= 𝒆 𝒓𝑻
In the context of stock prices this means that
𝐒 𝟎 ∗ 𝐞 𝐫𝐓
= 𝑺 𝑻
37. 37
Consequently,
𝐥𝐧(
𝑺 𝑻
𝐒 𝟎
) = 𝒓𝑻
so that once we assume the returns for a stock to be a normal random variable, the
stock price itself becomes dimensioned as that of a lognormal random variable
since,
𝑺 𝑻
𝐒 𝟎
= 𝒆 𝒙
where
𝑿~𝑵(𝝁, 𝝈 𝟐
)
Since the sum of normal random variables is also normal, by extension, the sum of
lognormal random variables is also lognormal. This means that if we assume stock
returns to be independent over time, this means that the total returns are
38. 38
𝑬 𝑺 = 𝑬[𝑹] 𝒕
𝒏
𝒕!𝟎
since in general
𝑬 𝒏𝑺 = 𝒏𝑬[𝑺]
and that the variance of the total returns is
𝑽𝒂𝒓 𝑺 = 𝑽𝒂𝒓[𝑹] 𝒕
𝒏
𝒕!𝟎
since in general
𝑽𝒂𝒓 𝒏𝑺 =
𝒏 𝟐
𝑽𝒂𝒓[𝑹] 𝒕
𝒏
= 𝒏𝑽𝒂𝒓[𝑹] 𝒕
39. 39
4.2 Black Scholes
The Black-Scholes formula provides an equation of value for the price of an
option. It calculates the price of the option as a consideration of six factors: Stock
Price (S), Strike Price (X), Dividend yield (𝛿), Volatility (𝜎), Interest rate (r),
Time (T), and for a (European) call is written as
𝐒𝒆!𝜹𝑻
𝑵(𝒅 𝟏) − 𝐊𝒆!𝒓𝑻
𝑵(𝒅 𝟐)
where
𝒅 𝟏 =
𝐥𝐧(
𝑺
𝑲
) + (𝒓 − 𝜹 −
𝝈 𝟐
𝟐
)𝑻
𝝈 𝑻
and
𝒅 𝟐 = 𝒅 𝟏 − 𝝈 𝑻
and where 𝑁 is (calculated as) the CDF for the standard normal distribution.
Where this formula becomes essential to our previous discussion is that these
formulas can be written to calculate the price of the same option with Prepaid
forward prices since
𝒅 𝟏 =
𝐥𝐧(
𝑺
𝑲
) + (𝒓 − 𝜹 −
𝝈 𝟐
𝟐
)𝑻
𝝈 𝑻
40. 40
can also be written as
𝒅 𝟏 =
𝐥𝐧(
𝑺𝒆!𝜹𝑻
𝐊𝒆!𝒓𝑻) + (
𝝈 𝟐
𝟐
)𝑻
𝝈 𝑻
which can then be written as
𝒅 𝟏 =
𝐥𝐧(
𝐅𝟎,𝐓
𝐏
(𝑺)
𝐅𝟎,𝐓
𝐏
(𝑿)
) + (
𝝈 𝟐
𝟐
)𝑻
𝝈 𝑻
and the final Black Scholes Formula can then be written in terms of Prepaid
Forward Prices as

5. INSURANCE AND RISK MANAGEMENT STRATEGIES
We next consider the structure of the insurance pricing models, and discuss their
applicability to the derivative markets, and various extensions of their principles to
risk management, and risk management strategies.
5.1 Premiums
The essential net gain of any insurance company is the collection of premiums
from the pool of insured persons paid by those insured persons in exchange for a
guaranteed protection from the risk of potential unwanted liabilities. A company
that sells insurance contracts should therefore concern itself not only with potential
claim payouts, but should also be interested in knowing whether there is an
exposure to the risk of the claims exceeding the corresponding premiums collected
for that policy. Consider the following scenario7
where the total claim amount for a
health insurance policy follows a distribution with density function
𝒇 𝒙 =
𝟏
𝟏𝟎𝟎𝟎
𝒆!(
𝒙
𝟏𝟎𝟎𝟎
)
, 𝒙 > 𝟎
If we set the premium for the policy at the expected total claim amount plus 100,
we may interested to calculate the approximate probability that the insurance
company will have claims exceeding the premiums collected, if for example100
policies are sold. We can clearly see that claims for one policy is
7
This question is from the SOA/CAS Sample questions for Exam Probability/1, Question 85
42. 42
Exp. ~ 1000, 1000!
, and thus the premium is 1100, the total for all 100 claims is
Exp. ~ 100,000, 10,000!
, and the total for all premiums is 110,000. If we
standardize the distribution using the standard normal by subtracting 𝜇 and then
dividing by 𝜎 we get
𝒁 > [(
𝒙!𝝁
𝝈
) = (
𝟏𝟏𝟎,𝟎𝟎𝟎!𝟏𝟎𝟎,𝟎𝟎𝟎
𝟏𝟎,𝟎𝟎𝟎
) = 1] = .1587
It is therefore evident by extension, that in order to be able to calculate and manage
the risk inherent in the purchase and sale of options and hedge a position in the
option market, there must be a well-defined distribution model in order to ensure
that the premiums received for the options will produce a positive profit. The
structure of the pricing of premiums in the option market therefore, can be seen as
identical to that of the insurance pricing of premiums.
5.2 Deductibles
A key feature of insurance contracts, is a stipulation of a deductible where the
insurer only makes payment above a particular amount of loss. There can also exist
an upper deductible, where the insurer need not make payment beyond a particular
loss amount. Mathematically, where 𝑦 is the payment, 𝑥 the loss amount, 𝑑 the
deductible, and 𝑢 the upper deductible, these can be written as
𝒇 𝒚 =
𝟎 , 𝒙 < 𝒅
𝒙 − 𝒅, 𝒙 > 𝒅
43. 43
and
𝒇 𝒚 =
𝒙 , 𝒙 < 𝒖
𝒖 , 𝒙 > 𝒖
respectively.
There can also exist a contract where both of these conditions apply so that the
payment is distributed as
𝒇 𝒚 =
𝟎 , 𝒙 < 𝒅
𝒙 − 𝒅 , 𝒅 < 𝒙 < 𝒖
𝒖 , 𝒖 < 𝒙
This scheme of payment is an essential difference between the insurance market,
and the option market. Seemingly, there can exist the possibility in the financial
markets for an investor to want to purchase insurance for when a particular asset
decreases in value, but is also willing to bear losses that are below a certain fixed
level. This is essentially a deductible in the insurance market, and can in fact exist
in the options market as well8
. Suppose for example that one is only concerned
with large losses for a particular asset, either because only large losses are
expected, or because of the lack of funds that would be required to compensate
such a loss. Because small losses are not a concern, there is no logical reason to
pay a premium for small losses and one would rather agree to pay the ‘deductible’,
8
See for example Bellalah Chapter 21, for a discussion on many different types of Exotic Options,
including Pay-later, Chooser, Compound, Forward Start, Gap, Barrier, and Binary Options, and also
options on Maximum, or Minimum of two assets. Under a gap option (pp.906) the structure of the option
would in fact seem to be conceptually reminiscent to a deductible for an insurer.
44. 44
in the event of peril. By extended reasoning, similar discussion is applicable for
that of upper deductibles and from the perspective of the writer of such options.
Another scenario of where the concept of a deductible could be applicable in the
option market is where there is an estimated probability that an asset will go down
to 0, but there is a model for any losses above 0. This is best illustrated by

: Suppose that an auto insurance company insures an automobile worth
15,000 for one year under a policy with a 1,000 deductible. During the policy year
there is a 0.04 chance of partial damage to the car and a 0.02 chance of a total loss
of the car. If there is partial damage to the car, the amount of damage (in
thousands) follows a distribution with density function

In order to calculate the expected claim payment we need to consider all the
possible circumstances of peril, and in the case of partial losses perform integration
by parts so that we have:

In the options market, the analysis of an asset based on a model that has a
piecewise function such as this one would be extremely beneficial to an investor
who estimates these probabilities of risk exposure. An optimal strategy that would
follow from this expected claim amount would be to allocate the written put or
selling of the insurance contract, in a way that can resemble and therefore replicate
the possible claim amount. This will not only ensure the insurers capacity for
liability payments in the event of peril but also lower the cost for the investor, and
ultimately provide a customized insurance strategy for the investor just as it would
for any insurance company. By further creativity and modeling, these and other
similar strategies can thus become an integrated and innovative approach to
enhancing and developing the derivative markets.

5.3 Investment Strategies and Asset Liability Management
Typically, an insurance company predicts its ability to provide reimbursement for
losses to its policyholders through monitoring and managing its investments
through asset liability matching and immunization strategies. Following our
previous discussion the optimization of these strategies can be significantly
enhanced by understanding how to structure these asset liability and matching
strategies. This again can best be illustrated by example:
Suppose10
we wish to calculate the amount of each bond that an investor should
purchase to exactly match its liabilities where it must pay liabilities of 1,000 due 6
months from now and another 1,000 due one year from now. Further suppose that
there are two available investments: A 6-month bond with face amount of 1,000,
an 8% nominal annual coupon rate convertible semiannually, and a 6% nominal
annual yield rate convertible semiannually; and a one-year bond with face amount
of 1,000, a 5% nominal annual coupon rate convertible semiannually, and a 7%
nominal annual yield rate convertible semiannually. Because only Bond II provides
a cash flow at time 1, it must be considered first. The bond provides 1025 at time 1
and thus 1000/1025 = 0.97561 units of this bond provides the required cash. This
bond then also provides 0.97561(25) = 24.39025 at time 0.5. Thus Bond I must
provide 1000 – 24.39025 = 975.60975 at time 0.5. The bond provides 1040 and
thus 975.60975/1040 = 0.93809 units must be purchased.
If we now suppose that in such an immunization there arises some probability that
say the one year zero coupon bond will actually default and not be able to meet the
payment of its redemption value, we may want to hedge this investment against
such a risk and estimate that we need to allocate more funds into the 6 month zero

coupon bond since we know that investment to not contain any element of risk. As
with our previous example of a piecewise function for a deductible, a similar
calculation can be made here in order to restructure the payment scheme to manage
the asset liability matching and immunization strategy for this position. Let us
assume that the risk of default, say 𝑑, is 4%, for the one thousand dollars for the
one year zero coupon bond and in the event of default, is distributed as
𝒇 𝒅 = 𝒇 𝒙 = 𝒙 𝟐, 𝟎 < 𝒙 < 𝟏
so that the total probability distribution for the default is

We can therefore conclude that in order to ensure the 1025 at time one, a different
amount of the bond must be purchased since it really only has an expected value of
1 - 0.01333 = 0.98666(1025) = 1,011.333
1000/1011.33 = 0.98879 units of this bond provides the required cash. This bond
then also provides 0.98879(25) = 24.71975 at time 0.5. Thus Bond I must provide
1000 – 24.71975 = 975.28025 at time 0.5. The bond provides 1040 and thus
975.28025/1040 = 0.937769 units must be purchased.
We summarize these differences in Table A-1 below:

5.4 Risk Assumptions and Classes
We conclude our paper with an important observation about general risk
assumptions and assessments that must be considered by insurers and investors,
since these are an important aspect of actuarial principle. There is an inherent goal
among insurers that on average a policyholder’s premium must be proportional to
his or her particular loss potential, as measured by specific rating variables. A plan
can then categorize potential customers based on the values of the rating variables.
In a competitive insurance market, insurers may constantly be refining their class
plans. Since as we have previously noted, the sale of insurance, is analogous to the
writing of a put option in the options market, we can reason that an investor who
wishes to measure his potential exposure to risk from his writing a put contract on
a selection of any given assets must often be able to class the risk of those assets.
Similarly, an investor who simply wants to short a portfolio of some group of
assets, must also be able to class the risk of those assets. In an optimal risk
management setting, it is important to identify the key risk indicators to use as
rating variables, and the discounts or surcharges based on their value.
These classes and risk variables can prove to be the greatest foundation for any
risk management procedure. For example, consider the following data of losses for
a group of 1000 policyholders, where we class according to age and health:
Age
Health
Poor Average
0-50 35% 10%
50-100 30% 25%
TABLE A-2. EXAMPLE OF DATA LOSSES BY AGE AND HEALTH CLASS
50. 50
If we class each group separately, we may be able to model the loss distribution in
a way such as the following:
Age
Health
Poor Average

We may want to consider a particular age of having some tendency towards lower
losses, for example 0-50, since overall they only account for 45% of all losses.
Because we would be grouping the class in a different way our loss distribution
model would change as would our expected payout. Similarly, we may want to say
51. 51
that a particular level of health is more prone towards a lower level of losses, for
example that of the average health class who account for only 35% of all losses.
This too would require us to choose a new frequency of loss distribution for each
health class. A third consideration may be to want to say that a tendency towards
lower losses due to health factors, may itself be because those health factors
themselves are a result of age. This would again require us to mitigate the original
loss assumption models and would ultimately change our expected payout. We
thus that in order to be able to understand and properly modify model loss
distributions, and thereby assess and manage risk we must also be aware of the
foundational and fundamental importance of risk assumptions and classes.

6.CONCLUSION
This paper has been written as a foundational tool to understand the broader
structure of the derivative markets, and in which ways they can be seen as a
parallel to the insurance industry.
We have developed and explained the relevance of numerous financial
instruments, in the context of risk management, as well as provided clarification of
actuarial methods and principles.
We have showed significant attention towards understanding the relevancy of
insurance models, including payment and loss distributions, and how these affect
asset liability management and risk classes and assumptions.
We have displayed through mathematical and logical comparison, the effects that
insurance models can have on an asset, and showed that a further understanding of
these principles can platform a more adequate and strategic position held by an
investor in the derivative markets.
