Bad Beta, Good Beta
By John Y. Campbell And Tuomo Vuolteenaho
Presentation by Michael-Paul James
Cash flow and discount rate betas estimates stock market risk factors
more efficiently than CAPM over time.
○ Cash flow news
■ Stock returns covariance with cash flows news
○ Discount rate news
■ Stock returns covariance with discount rate news
● “Bad” cash flow beta (risk) demands higher premiums than “good”
discount rate beta (risk).
● Value and small stocks have higher cash flow betas than growth and
large stocks on average.
● High average returns on value and small stocks are appropriate
compensation for risk, not an unrealized benefit to ownership.
● Overweighting small and value stocks benefit low risk aversion equity
investors
● Underweighting small and value stocks benefit high risk aversion
equity investors
● Model offers strong explanatory power in the cross section of asset
returns with theoretical values
● ICAPM outperforms the CAPM in empirical research
A pair trade is the taking of a long position in one security together with an equal short position in another that is strongly correlated with it. It is sometimes used to refer to multiple long and short positions that are similarly matched.
"From Alpha Discovery to Portfolio Construction: Pitfalls and Solutions" by D...Quantopian
From QuantCon 2017: Implementation is the efficient translation of alpha research into portfolios. It includes portfolio construction and trading. It is a vital step in the quant equity workflow, as poor implementation can ruin even the best alpha ideas. Two crucial challenges must be solved: how to construct a portfolio that most efficiently captures a given alpha signal; and, in the presence of multiple signals, how to optimally combine them into a single composite alpha factor.
This talk addresses these challenges, examines common pitfalls in the implementation of quantitative strategies and good practices to avoid them. A common theme is striking the right balance between factor signal purity and investability. We look at how factor models and optimisation techniques help professional investors answer three key questions:
· What risks should your risk model be cognisant of?
· What objective function should you use?
· What effect do investability constraints have on your portfolio?
A new type of legal contract
Using blockchain technology, smart contracts rely on computers to automatically enforce the rules and penalties of an agreement. While many have predicted that they will undermine the need for lawyers (while also opening new avenues for aggrieved parties to sue), smart contracts are already being used to transfer properties, purchase goods, and wire funds.
Is your firm ready to write and argue the intricacies of a smart contract?
Join Joshua Lenon, Clio’s Lawyer in Residence, and Amy Wan, Esq., Founder of Sagewise and author of the Bloomberg Law guide on Initial Coin Offerings and the LexisNexis Private Equity Practice Guide, as they explore how smart contracts will affect the future of legal practice.

Financial risk refers to the probability that actual returns will differ from expected returns on an investment. The main types of financial risk are credit risk, liquidity risk, interest rate risk, market risk, and operational risk. Credit risk arises from the possibility of default or decline in the credit quality of counterparties. Liquidity risk stems from the inability to raise funds or sell assets quickly with minimal loss of value. Interest rate risk is the sensitivity of assets and liabilities to changes in interest rates.
This document outlines the key components of enterprise risk management (ERM), including identifying risks, assessing risks, and developing strategies to respond to risks. It discusses ERM frameworks, the benefits of ERM, and the various risk management processes involved. Specifically, it describes the eight components of an ERM framework as establishing internal environment, objective setting, risk identification, risk assessment, risk response, control activities, information and communication, and monitoring.
Automatic Personality Prediction with Attention-based Neural NetworksJinho Choi
Distributional Semantic word representation allows Natural Language Processing systems to extract and model an immense amount of information about a language. This technique maps words into a high dimensional continuous space through the use of a single-layer neural network. This process has allowed for advances in many Natural Language Processing research areas and tasks. These representation models are evaluated with the use of analogy tests, questions of the form ``If a is to a' then b is to what?'' are answered by composing multiple word vectors and searching the vector space. During the neural network training process, each word is examined as a member of its context. Generally, a word's context is considered to be the elements adjacent to it within a sentence. While some work has been conducted examining the effect of expanding this definition, very little exploration has been done in this area. Further, no inquiry has been conducted as to the specific linguistic competencies of these models or whether modifying their contexts impacts the information they extract. In this paper we propose a thorough analysis of the various lexical and grammatical competencies of distributional semantic models. We aim to leverage analogy tests to evaluate the most advanced distributional model across 14 different types of linguistic relationships. With this information we will then be able to investigate as to whether modifying the training context renders any differences in quality across any of these categories. Ideally we will be able to identify approaches to training that increase precision in some specific linguistic categories, which will allow us to investigate whether these improvements can be combined by joining the information used in different training approaches to build a single, improved, model.
This chapter discusses the risks associated with off-balance sheet activities at financial institutions. While off-balance sheet activities are often used to hedge risks, they can also pose substantial risks as demonstrated by several high-profile cases of losses. Regulatory policies have been updated in response to accounting issues and unethical practices related to off-balance sheet activities. Off-balance sheet activities include derivatives, contingent assets and liabilities, and other transactions recorded off a company's balance sheet.

The presentation I gave in my investment class about paris trading. I implemented a experiment using R language to identify good pairs from S&P 100 universe. The algorithm is to perform ADF test on the spread of two random stocks and find out the pairs with stationary spread (co-integrated pairs). Pairs identification period is from 2010/11 to 2012/10, test period is from 2012/11 to 2013/12. Finally I got 33 pairs out of 4950 candidates, and I conduct a summary on the experiment result.
Treasury operations in banks involve managing investments, foreign exchange transactions, derivatives trading, and funds management. This includes maintaining statutory liquidity and cash reserve ratios, deploying surplus funds, hedging risks, and trading in financial markets. Key functions of the treasury division are investments in securities, currency trading, derivatives trading like swaps and options, and funds management activities. The treasury aims to meet regulatory requirements, earn profits, and mitigate risks through its operations.
Supporting trade finance with letters of credit on cordaR3
This document discusses using Corda and blockchain technology to support trade finance through letters of credit. It provides an overview of Corda and its goals in trade finance, including payments, KYC/KYS, and negotiable title documents. The document outlines R3's focus on trade business networks, invoice management solutions, and core banking providers. It then demonstrates a scenario of using Corda for electronic bills of lading and describes the components of a Corda application, including states, contracts, and flows.
This document provides guidance on building an effective investment portfolio through diversification and managing risk. It recommends creating an asset allocation policy based on your risk tolerance that diversifies across asset classes like stocks and bonds. Specific funds should then be selected within each asset class and regularly monitored to ensure the portfolio still matches your goals and risk profile as markets change over time. The focus should be on long-term growth while minimizing downside risk through this diversified, balanced approach.
Credit risks are calculated based on the borrowers’ overall ability to repay. Our objective was to use optimization in order to create a tool that approves or rejects loans to borrowers. We also used optimization to establish how much interest rate/credit will be extended to borrowers who were approved for a loan.
Automated Selection and Robustness for Systematic Trading Strategies by Dr. T...Quantopian
Presented at QuantCon Singapore 2016, Quantopian's quantitative finance and algorithmic trading conference, November 11th.
Even with a wide range of statistical tools available, selection of algorithmic trading strategies can
leave the trader with significant out-of-sample variability. In most cases the final decision making
is still a manual process.
This presentation will show how a combination of statistical methods and machine learning can help to automate strategy selection and boost the robustness of automated trading systems.
"Portfolio Optimisation When You Don’t Know the Future (or the Past)" by Rob...Quantopian
We generally assume the past is a good guide to the future, but well do we even know the past? What effect does this uncertainty when estimating inputs have on the notoriously unstable algorithms for portfolio optimization?
I explore this issue, look at some commonly used solutions, and also introduce some alternative methods.
"Quant Trading for a Living – Lessons from a Life in the Trenches" by Andreas...Quantopian
It takes hard work, skill and time to develop robust trading models, but that is just the beginning of the journey. The question then is what you can do with it, and how to go about building a career in quant finance.
If your plan is to move beyond hobby trading and build a career in in the professional quant trading field, the work is not over once you have a great model.
This presentation will discuss how to leverage your trading models into building a successful career in quant trading. We will look at the various options available, and their respective merits and faults. Whether you want to trade your own money for a living, find a job in the industry or build your own business, your model design will have to be adapted to your aim. We will discuss what type of models and results there is a market for, how to go about finding investors for your trading, and how the real economics of the business look.
This document discusses the management of interest rate risk in banks. It defines interest rate risk and explains the main sources of this risk for banks, including re-pricing risk, basis risk, embedded option risk, and yield curve risk. The document then discusses tools for analyzing and measuring interest rate risk, such as gap analysis, simulation models, and rate shift scenarios. Managing interest rate risk is important for banks since their main source of profit relies on the difference between the interest rates paid on liabilities and earned on assets.
The document discusses various interest rate derivatives products including forward rate agreements (FRAs), interest rate swaps, and options. It provides details on FRAs, including how they work, examples of FRA deals and calculations, and potential benchmarks. It also covers interest rate swaps, including how they are analogous to FRAs, common uses of swaps, and criteria for floating rate benchmarks. The document concludes with an overview of overnight index swaps and constant maturity swaps.

This chapter discusses bonds and the bond market. It covers various types of bonds including Treasury bonds, municipal bonds, and corporate bonds. It also examines how bond yields are calculated, how to value coupon bonds, and that bonds are a popular long-term investment alternative to stocks, with the bond market issuing over 5 times as much new debt as new equity annually. The purpose of capital markets is to provide long-term financing, with governments and corporations issuing securities that are purchased by investors.
"Enhancing Statistical Significance of Backtests" by Dr. Ernest Chan, Managin...Quantopian
Insufficient historical data is a major hurdle in building a trading model free from data snooping bias. Dr. Chan's talk will discuss several techniques, some borrowed from machine learning, that can alleviate overfitting and enhance the statistical significance of a backtest.
This document provides an introduction to Forex trading basics. It covers the Forex market, key terms like pips and candlestick charts, trading strategies and patterns. The best times to trade are Tuesday through Thursday between 3am-12pm EST while London and New York sessions overlap. Candlestick patterns can help determine when to enter or exit trades. Successful trading requires education, having a trading plan and rules, removing emotions from decisions, and adopting the right mindset.
The document outlines a risk governance framework with the CEO responsible for establishing systems to identify and manage risk. The Board reviews these systems and their effectiveness. The Risk & Audit Committee oversees risk management and reviews internal controls and risk management systems.
This document discusses risk reporting and risk management. It defines risk reporting as communicating risk-related data and facts through reports to the appropriate parties. Effective risk reporting allows for clear communication across an organization. It then describes the objectives, levels, and types of internal and external risk reporting. It also discusses limitations of risk reporting and major types of risk reports. The document also defines risk management, describes types of risks, and methods to manage risks, including avoiding, retaining, transferring, sharing risks, and reducing risks through various financial measures.

Directly modeling discount rate news and backing out cash flow news
adds residual news to the latter
○ The method has led to erroneous conclusions:
■ Larger relative DR variance
■ Value stocks earn higher returns due to higher βCF
■ βCF is more important than total βtotal
○ DR news cannot be accurately estimated (low predictive power)
and backed out CF news inherits large misspecification error of DR
○ Modeled Treasury bonds reveals higher CF variance with no real CF
risk
○ Minor changes in predictive variables produce opposite results
Directly modeling cash flow news, discount rate news, and residual
○ Value firms have both lower modeled CF betas and DR betas, but
higher residual betas, indicating that the results in the current
literature are driven by the residual news.

Poster on Learning financial shocks and the Great RecessionGRAPE
We build a simple theoretical model featuring financial markets and imperfect information: consumers, workers, and firms observe and learn continuously about the world they live in. We find that not only financial shock but also what people thought of it mattered for the economy.
Agents gradually learn the structure of the economy.
Learning model delivers a sizeable recession in 2008-2010,
...whereas RE model predicts a counterfactual expansion.
In a medium scale model learning still matters.
Precautionary Savings and the Stock-Bond CovarianceEesti Pank
The document discusses the relationship between stock and bond returns and how their covariance varies over time. It presents several empirical findings, including that negative stock-bond covariance is associated with lower Treasury yields, wider corporate spreads, and negative subsequent returns on stocks and bonds. It then introduces a two-factor term structure model where the price of risk varies over time, which can generate time-varying stock-bond covariance as in the data. Simulation results from the model match several key empirical moments.
Trading Strategies Based on Market Impact of Macroeconomic Announcementsby A...Quantopian
1) The document discusses trading strategies based on the market impact of macroeconomic announcements. It analyzes 18 major US macroeconomic indicators from 2009-2013 and their impact on equity ETF returns on announcement days.
2) Key findings include several indicators having statistically significant impact on returns, including ISM Manufacturing Index, Non-Farm Payrolls, International Trade Balance, and Housing Starts. Trading strategies based on announcements of significant indicators achieved higher risk-adjusted returns than buy-and-hold.
3) The study also analyzes the impact of economic announcement surprises, actual changes, and expected changes. It found that strategies based on actual changes generally had the lowest volatility and performed well even before and after the
This document discusses the differences between the trading paradigms of low-frequency traders and high-frequency traders. It argues that while speed is an advantage for HFTs, the true divide is that HFTs operate under an "event-based time" paradigm using machine cycles rather than human chronological time. The document also examines predatory trading strategies used by some HFTs and compares two methods (tick rule and bulk volume classification) for classifying order flow imbalances, finding bulk volume classification better explains market impacts.
Business forecasting decomposition & exponential smoothing - bhawani nandan...Bhawani N Prasad
1. The document discusses various techniques for time series forecasting including time series decomposition, exponential smoothing, and moving averages.
2. Time series decomposition involves breaking down a time series into trend, seasonal, cyclical, and irregular components. Exponential smoothing assigns weights that decline exponentially to past observations to smooth the data and forecast future values.
3. The document provides an example of applying additive and multiplicative time series decomposition as well as exponential smoothing methods such as simple, Holt's, and Winter's to electricity sales data to generate forecasts. It compares the accuracy of different forecasting techniques.
The document presents 12 new scaling laws discovered from analyzing high-frequency tick data from 13 currency pairs over 5 years. The scaling laws characterize properties like the average number of price moves per year, average duration of price moves and directional changes, and how total price moves decompose into directional changes and overshoots. Intrinsic time is proposed as an event-based approach to address issues like non-linear market movements and seasonality seen in high-frequency data.

How important are the rules used to create smart beta portfoliosRalph Goldsticker
Most Smart Beta presentations are about: “What and Why?”
This presentation addresses: “Do the rules used to construct a Smart Beta portfolio matter?”
Our approach was to use alternative portfolio construction rules to simulate multiple 25-year return histories for Low Volatility, Fundamental Indexing and Momentum strategies, and then compare their average returns, risks, drawdowns and factor exposures.

Predicting Excess Stock Returns
Out of Sample: Can Anything Beat
the Historical Average?
Paper by John Y. Campbell & Samuel B. Thompson
Presentation by Michael-Paul James
● Many variables are correlated with subsequent stock returns
● In the previous research, historical average stock returns have
outperformed most contenders
● Predictor variables in this paper outperformed out-of-sample once
restrictions were imposed on coefficient signs and return forecast
○ Small explanatory power, meaningful economic significance
● Although not fully described asset prices, out-of-sample performance
improves.
● Models generate meaningful utility gains for mean-variance investors
● Data accessibility and improvement may prove more valuable than
theoretical restrictions
The document describes an estimated dynamic stochastic general equilibrium (DSGE) model of the Indian economy that incorporates important features like financial frictions and both formal and informal sectors. It estimates three nested models of increasing complexity and finds strongest support for the two-sector model with financial and labor market frictions. This model provides estimates of the size of India's informal sector from Bayesian maximum likelihood estimation and better matches key macroeconomic moments compared to simpler models.
This report analyzes the Three Stars investment fund. It first examines the fund's return characteristics, finding the fund had a higher mean return but also higher risk than the market index. It then evaluates the fund's performance using several metrics. Sharpe and Treynor ratios found the fund offered greater risk-adjusted returns than the market. The report also conducts market timing analysis and concludes the fund was able to time the market to some degree to maximize returns. Overall, the analysis finds the fund performed well but also carried higher risk than the market.

The document analyzes the relationship between stock market performance and economic growth in the U.S. from 1980-2011. It finds a strong positive correlation between changes in the Dow Jones Industrial Average and nominal GDP. Regression analysis shows stock market fluctuations explained about 87% of the variation in GDP. The results suggest stock prices can influence economic activity by affecting business confidence, financing, and household wealth. Therefore, large declines in stock prices may precede and prolong economic downturns.

Firm level shocks propagate in production networks
● Customers drop 2-3% in sales growth when suppliers suffer a disaster
○ 25% drop in sales growth with respect to sample average of 10%
○ Temporary effect, without prior trends
○ Losses only affect active customer-supplier relationships
○ Larger effect when supplier produces differentiated goods with
high R&D, more patents, thus difficult to replace
○ Customer suffers 1% drop in market equity value
● Other suppliers experience drop in sales growth after another supplier
is hit, when customers are shared.
● Input disruptions are not compensated, resulting in sector wide losses
● Input specificity is a key determinant of the propagation of
idiosyncratic shocks in the economy

The document summarizes a research paper that examines hypotheses for property-liability insurer reserve errors. It analyzes two measurements of reserve error and tests four main hypotheses from the literature - taxes, income smoothing, rate regulation incentives, and financial weakness. The results found that the choice of reserve error measurement impacted the findings. There was little evidence for income smoothing. Evidence supported overreserving for tax purposes under one measurement but not the other. Rate regulation incentives were supported. Financial weakness was linked to underreserving rather than deception.

“Amidst Tempered Optimism” Main economic trends in May 2024 based on the results of the New Monthly Enterprises Survey, #NRES
On 12 June 2024 the Institute for Economic Research and Policy Consulting (IER) held an online event “Economic Trends from a Business Perspective (May 2024)”.
During the event, the results of the 25-th monthly survey of business executives “Ukrainian Business during the war”, which was conducted in May 2024, were presented.
The field stage of the 25-th wave lasted from May 20 to May 31, 2024. In May, 532 companies were surveyed.
The enterprise managers compared the work results in May 2024 with April, assessed the indicators at the time of the survey (May 2024), and gave forecasts for the next two, three, or six months, depending on the question. In certain issues (where indicated), the work results were compared with the pre-war period (before February 24, 2022).

Michael-Paul James
● CAPM
○ Beta with the market portfolio of all invested wealth measures a
stock’s risk, not other characteristics should influence a rational
investors required return.
○ CAPM fails after 1960 in empirical tests
■ Small and value stocks delivered higher average returns then
their beta suggests.
■ High past betas produce similar returns to low past betas
controlling for size
■ Empirical biases favors small and value stocks with low betas.
5. Measuring Stock Market Risks
5
Michael-Paul James
● Two components of the market portfolio
○ News about future cash flows
■ Bad news: Wealth decreases and investment opportunities
remain the same
○ News about changes in the discount rate or cost of capital
■ Bad news: Wealth decreases but future investment
opportunities improve
○ Assumption
■ Investors demand higher premiums on assets that covary with
cash flow news than covary with discount rates which are
compensated with higher potential future returns
6. Measuring Stock Market Risks
6
Michael-Paul James
● Division of news
○ Cash flow beta
○ Discount rate beta
● Merton’s (1973) ICAPM
○ Discount rate beta equals the variance of the market return
○ Cash flow beta equals γ (relative risk aversion) times the variance of
the market return
■ If γ > 1 then the risk averse investor demand a higher premium
for cash flow risk
● Labeling
○ Bad cash flow beta (high risk premium) versus (relatively) good
discount rate beta (low risk premium)
7. Measuring Stock Market Risks
7
Michael-Paul James
● Improvements to the model
○ After 1963, the two beta model (ICAPM) improves predictive power
over CAPM
■ Possibly explains:
● Why growth stocks with high (good) betas have lower
average returns.
● Why value stocks with high (bad) betas have high average
returns.
8. Measuring Stock Market Risks
8
Michael-Paul James
● Campbell’s (1993) improvement to ICAPM
○ Solves discrete time empirical version
○ Assumes asset returns are homoskedastic
■ Variance of the residual (error term) is constant.
○ Investor has recursive preferences
■ Describe trade-offs between current and future consumption
using with the certainty equivalent of next period's utility
(single index for future)
9. Measuring Stock Market Risks
9
Michael-Paul James
● Paper improvements
○ Small stock value spread to predict aggregate stock returns.
■ Empirically high returns to small growth stocks forecast low
returns on the aggregate stock market
■ Hypothetically due to negative correlation with innovations to
investment opportunities

m,t+1
: Excess market return
■ Log (value weighted index / treasury bills)
○ TY: Yield spread between long term and short term bonds
■ 10 year constant maturity taxable bond yield / short term taxable notes
■ Tracks business cycle
○ PE: Market’s smoothed price-earnings ratio
■ Log (S&P 500 price index / 10-year moving average of S&P earnings)
■ High PE = low long run expected returns (constant earnings growth)
○ VS: Small-stock value spread
■ Log (book-to-market ratios of small value and small growth)
■ ICAPM motivated: more sensitive to changes in discount rates, equity
market, and financial conditions.

Notes: The table shows the descriptive statistics of the VAR state variables estimated from the full sample period 1928:12–2001:12, 877 monthly
data points. rM e is the excess log return on the CRSP value-weighted index. TY is the term yield spread in percentage points, measured as the
yield difference between ten-year constant-maturity taxable bonds and short-term taxable notes. PE is the log ratio of the S&P 500’s price to the
S&P 500’s ten-year moving average of earnings. VS is the small-stock value-spread, the difference in the log book-to-market ratios of small value
and small growth stocks. The small-value and small-growth portfolios are two of the six elementary portfolios constructed by Davis et al. (2000).

Notes: The table shows premia estimated from the 1929:1–1963:6 sample for an unrestricted factor model, the two-beta ICAPM, and the CAPM.
The test assets are the 25 ME- and BE/ME-sorted portfolios and 20 risk-sorted portfolios. The second column per model constrains the
zero-beta rate (Rzb
) to equal the risk-free rate (Rrf
). Estimates are from a cross-sectional regression of average simple excess test-asset returns
(monthly in fractions) on an intercept and estimated cash-flow (βCF
) and discount-rate betas (βDR
). Standard errors and critical values [A] are
conditional on the estimated news series and (B) incorporating full estimation uncertainty of the news terms. The test rejects if the pricing
error is higher than the listed 5 percent critical value.

28. Robustness checks
28
Michael-Paul James
● Small sample bias
○ Negligible bias in VAR coefficient of returns on value spread (VS)
○ Little bias in estimated volatility of CF and DR news
○ Upward bias in negative CF and DR coefficients on VS
● Conditional pricing
○ Estimate covariences for each test asset with rolling 3-year window
○ Regress realized cross products on lagged rolling covariance
estimates and dummies in two pooled regressions
○ Regress realized simple excess returns on fitted conditional
covariances with restrictions
29. Robustness checks
29
Michael-Paul James
● Sensitivity to ρ
○ Based on a priori knowledge not estimations
○ Value of ρ has little impact on results except when zero-beta is
restricted to treasury-bill rate
● Data frequency
○ Repeated monthly tests with quarterly and annual data with
similar results in magnitude and direction.
● Sensitivity to additional state variables
○ Added treasury bill rate and log dividend price ratio with similar
results
30. Loose ends and future directions
30
Michael-Paul James
● Assumes constant variance for market returns, cash flow news, and
discount rate news.
● Assumes rational long term investor always holds a constant
proportion of assets in equities
○ No incentive to time the market
● No discussion of source of variation in the market’s discount rate
● No discussion of how CF and DR betas are linked to the underlying
cash flows of value and growth firms.
● Primary determinant of cost of capital is not market beta but cash flow
of a project.
32. Summary
32
Michael-Paul James
● Cash flow and discount rate betas estimates stock market risk factors
more efficiently than CAPM over time.
○ Cash flow news
■ Stock returns covariance with cash flows news
○ Discount rate news
■ Stock returns covariance with discount rate news
● “Bad” cash flow beta (risk) demands higher premiums than “good”
discount rate beta (risk).
● Value and small stocks have higher cash flow betas than growth and
large stocks on average.
33. Summary
33
Michael-Paul James
● High average returns on value and small stocks are appropriate
compensation for risk, not an unrealized benefit to ownership.
● Overweighting small and value stocks benefit low risk aversion equity
investors
● Underweighting small and value stocks benefit high risk aversion
equity investors
● Model offers strong explanatory power in the cross section of asset
returns with theoretical values
● ICAPM outperforms the CAPM in empirical research
