1. Derivatives
A financial contract of pre-determined
duration, whose value is derived from
the value of an underlying asset
Securities
commodities
bullion
precious metals
currency
livestock
index such as interest rates, exchange
rates
2. What do derivatives do?
Derivatives attempt either to minimize
the loss arising from adverse price
movements of the underlying asset
Or maximize the profits arising out of
favorable price fluctuation. Since
derivatives derive their value from the
underlying asset they are called as
derivatives.
3. Types of Derivatives
(UA: Underlying Asset)
Based on the underlying assets
derivatives are classified into.
Financial Derivatives (UA: Fin asset)
Commodity Derivatives (UA: gold etc)
Index Derivative (BSE sensex)
4. How are derivatives used?
Derivatives are basically risk shifting
instruments. Hedging is the most
important aspect of derivatives and also
their basic economic purpose
5. How are derivatives used?
Derivatives can be compared to an
insurance policy. As one pays
premium in advance to an insurance
company in protection against a
specific event, the derivative
products have a payoff contingent
upon the occurrence of some event
for which he pays premium in
advance.
6. What is Risk?
The concept of risk is simple. It is
the potential for change in the price
or value of some asset or
commodity. The meaning of risk is
not restricted just to the potential for
loss. There is upside risk and there is
downside risk as well.
7. What is a Hedge
To Be cautious or to protect against loss.
In financial parlance, hedging is the act
of reducing uncertainty about future price
movements in a commodity, financial
security or foreign currency .
Thus a hedge is a way of insuring an
investment against risk.
9. Forward Contracts.
A one to one bipartite contract, which is to be
performed in future at the terms decided today.
Eg: Jay and Viru enter into a contract to trade
in one stock on Infosys 3 months from today
the date of the contract @ a price of Rs4675/-
Note: Product ,Price ,Quantity & Time have
been determined in advance by both the
parties.
Delivery and payments will take place as per
the terms of this contract on the designated
date and place. This is a simple example of
forward contract.
10. Risks in a forward contract
Liquidity risk: these contracts a
biparty and not traded on the
exchange.
Default risk/credit risk/counter party
risk.
Say Jay owned one share of Infosys
and the price went up to 4750/-
three months hence, he profits by
defaulting the contract and selling
the stock at the market.
11. Futures.
Future contracts are
organized/standardized contracts in
terms of quantity, quality, delivery time
and place for settlement on any date in
future. These contracts are traded on
exchanges.
These markets are very liquid
12. Futures.
In these markets, clearing
corporation/house becomes the
counter-party to all the trades or
provides the unconditional guarantee
for the settlement of trades i.e.
assumes the financial integrity of the
whole system. In other words, we
may say that the credit risk of the
transactions is eliminated by the
exchange through the clearing
corporation/house.
13. The key elements of a futures contract
are:
– Futures price
– Settlement or Delivery Date
– Underlying (infosys stock)
14. Illustration.
Let us once again take the earlier
example where Jay and Viru entered
into a contract to buy and sell Infosys
shares. Now, assume that this contract
is taking place through the exchange,
traded on the exchange and clearing
corporation/house is the counter-party
to this, it would be called a futures
contract.
15. Positions in a futures contract
Long - this is when a person buys a
futures contract, and agrees to
receive delivery at a future date. Eg:
Viru’s position
Short - this is when a person sells a
futures contract, and agrees to make
delivery. Eg: Jay’s Position
16. How does one make money in a
futures contract?
The long makes money when the
underlying assets price rises above
the futures price.
The short makes money when the
underlying asset’s price falls below
the futures price.
17. Options
An option is a contract giving the
buyer the right, but not the
obligation, to buy or sell an
underlying asset at a specific price
on or before a certain date. An option
is a security, just like a stock or bond,
and is a binding contract with strictly
defined terms and properties.
18. Options Lingo
Underlying: This is the specific
security / asset on which an options
contract is based.
Option Premium: Premium is the
price paid by the buyer to the seller
to acquire the right to buy or sell. It
is the total cost of an option. It is the
difference between the higher price
paid for a security and the security's
face amount at issue. The premium
of an option is basically the sum of
the option's intrinsic and time value.
19. Strike Price or Exercise Price :price of
an option is the specified/ pre-
determined price of the underlying asset
at which the same can be bought or sold
if the option buyer exercises his right to
buy/ sell on or before the expiration day.
20. Expiration date: The date on which
the option expires is known as
Expiration Date
Exercise: An action by an option
holder taking advantage of a
favourable market situation .’Trade
in’ the option for stock.
21. Exercise Date: is the date on which the
option is actually exercised.
European style of options: The
European kind of option is the one which
can be exercised by the buyer on the
expiration day only & not anytime before
that.
22. American style of options: An
American style option is the one
which can be exercised by the buyer
on or before the expiration date, i.e.
anytime between the day of
purchase of the option and the day
of its expiry.
23. Asian style of options: these are in-
between European and American. An
Asian option's payoff depends on the
average price of the underlying asset
over a certain period of time.
24. Call option: An option contract
giving the owner the right to buy a
specified amount of an underlying
security at a specified price within a
specified time.
Put Option: An option contract
giving the owner the right to sell a
specified amount of an underlying
security at a specified price within a
specified time
25. In-the-money: For a call option, in-
the-money is when the option's strike
price is below the market price of the
underlying stock. For a put option, in
the money is when the strike price is
above the market price of the
underlying stock. In other words, this
is when the stock option is worth money
and can be turned around and exercised
for a profit.
26. – Intrinsic Value: The intrinsic value of an
option is defined as the amount by which an
option is in-the-money, or the immediate
exercise value of the option when the
underlying position is marked-to-market.
For a call option: Intrinsic Value = Spot
Price - Strike Price
For a put option: Intrinsic Value = Strike
Price - Spot Price
28. Positions
Long Position: The term used when a
person owns a security or commodity
and wants to sell. If a person is long in
a security then he wants it to go up in
price.
Short position: The term used to
describe the selling of a security,
commodity, or currency. The
investor's sales exceed holdings
because they believe the price will fall.

33. Summary
The profit and loss profile for a short put
option is the mirror image of the long put
option. The maximum profit from this
position is the option price. The theoritical
maximum loss can be substantial should the
price of the underlying asset fall.
Buying calls or selling puts allows investor to
gain if the price of the underlying asset rises;
and selling calls and buying puts allows the
investors to gain if the price of the underlying
asset falls.
35. Stock Index Option
Trading in options whose underlying instrument
is the stock index.
Here if the option is exercised, the exchange
assigned option writer pays cash to the options
buyer. There is no delivery of any stock.
Dollar Value of the underlying index = Cash
index value * Contract multiple.
The contract multiple for the S&P100 is $100.
So, for eg, if the cash index value for the S&P is
720,then dollar value will be $72,000
36. For a stock option, the price at which the buyer
of the option can buy or sell the stock is the
strike price. For an index option, the strike
index is the index value at which the buyer of
the option can buy or sell the underlying stock
index.
37. For Eg: If the strike index is 700 for an S&P
index option, the USD value is $70,000. If an
investor purchases a call option on the
S&P100 with a strike of 700, and exercises
the option when the index is 720, then the
investor has the right to purchase the index
for $70,000 when the USD value of the
index is $72000. The buyer of the call option
then receive$2000 from the option writer.
38. Binomial Model for Option
Valuation
Current Price of the stock = S
Two possible values it can take next
year :- uS or dS ( uS> dS)
Amount B can be borrowed or lent at a
rate of r. The interest factor (1+r) may
be represented , for sake of simplicity ,
as R.
d<R<u.
Exercise price is E.
39. Value of a call option, just before expiration,
if the stock price goes up to uS is
Cu = Max(uS-E,0)
Value of a call option, just before expiration,
if the stock price goes down to dS is
Cd = Max(dS-E,0)
The value of the call option is
C=^S+B
^ = (Cu-Cd)/ S (u-d)
B = uCd-dCu/(u-d)R
40. Illustration:
S=200, u=1.4, d=.9 E=220 r=0.15 R=1.15
Cu = Max(uS-E,0) = Max(280-220,0)=60
Cd = Max(dS-E,0) = Max(180-220,0)=0
^=Cu-Cd/(u-d)S = 60/(1.4-.9)200=0.6
B=uCd-dCu/(u-d)R = -0.9(60)/0.5(1.15) = -93.91
(A negative value for B means that funds are
borrowed).
Thus the portfolio consists of 0.6 of a share plus a
borrowing of 93.91( requiring a payment of
93.91(1.15) = 108 after one year.
C=^S+B= 0.6*200-93.91 = 26.09
41. Swaps
An agreement between two parties to
exchange one set of cash flows for another.
In essence it is a portfolio of forward
contracts. While a forward contract involves
one exchange at a specific future date, a
swap contract entitles multiple exchanges
over a period of time. The most popular are
interest rate swaps and currency swaps.
42. Interest Rate Swap
Counter Party Counter Party
LIBOR
A B
Fixed Rate of 12%
Rs50,00,00,000.00 – Notional Principle
‘A’ is the fixed rate receiver and variable rate payer.
‘B’ is the variable rate receiver and fixed rate payer.
43. The only Rupee exchanged between the parties are
the net interest payment, not the notional principle
amount.
In the given eg A pays LIBOR/2*50crs to B once
every six months. Say LIBOR=5% then A pays be
5%/2*50crs= 1.25crs
B pays A 12%/2*50crs=3crs
The value of the swap will fluctuate with market
interest rates.
If interest rates decline fixed rate payer is at a
loss, If interest rates rise variable rate payer is at a
loss. Conversely if rates rise fixed rate payer profits
and floating rate payer looses.
