§ Define a derivative
§ Distinguish between exchange-traded and over-the-counter derivatives;
§ Examples: futures, forwards, swaps, options, exotics…

DERIVATIVES: DEFINITIONS AND USES
v A derivative is a financial instrument whose value depends on (or derives from)
the values of other, more basic, underlying variables.
§ Interest rate, foreign exchange, and equity derivatives.
§ Credit derivatives.
§ Electricity derivatives.
§ Weather derivatives.
§ Insurance derivatives.
9
WHY DERIVATIVES ARE IMPORTANT?
v
Derivatives play a key role in transferring risks in the economy
v The underlying
assets include stocks, currencies, interest rates, commodities, debt
instruments, electricity prices, insurance payouts, the weather, etc
v
Many financial transactions have embedded derivatives
v The real options
accepted
approach to assessing capital investment decisions has become widely
10
HOW DERIVATIVES ARE TRADED?
v Exchanged-traded markets
§ A derivatives exchange is a market where individuals and companies trade standardized
contracts.
§ The Chicago Board of Trade (CBOT) was established in 1848 to bring farmers and
merchants together.
ü Its main task was to standardize the quantities and qualities of the grains that were traded.
ü Within a few years, the first futures-type contract (to-arrive contract) was developed.
ü Speculators soon became interested in the contract and found trading the contract to be an
attractive alternative to trading the grain itself.
§ Chicago Mercantile Exchange (CME) was established in 1919.
§ CME and CBOT have merged to form the CME Group, which also includes the New York
Mercantile Exchange (NYME).
11
HOW DERIVATIVES ARE TRADED?
v Exchanged-traded markets
§ CBOE started trading call option on 16 stocks in 1973 and put option started trading in 1977.
§ Now, trades options on thousands of stocks and many different stock indices.
§ Traditionally open-outcry system
ü Traders physically meeting on the floor of the exchange, shouting, and sing a complicated
set of hand signals to indicate the trades they would like to carry out.
§ Switching to electronic trading
ü Algorithmic trading: use of computer programs to initiate trades, often without human
intervention
ü Reduce the costs
ü Improve trade execution speed
ü Create an environment less prone to manipulation
12
HOW DERIVATIVES ARE TRADED?
v Over-the-counter (OTC) markets
§ In terms of total trading volume, has become much larger than the exchange-traded market.
§ A telephone and computer-linked network of dealers.
§ Telephone conversations in the over-the-counter market are usually taped.
§ Banks, other large financial institutions, fund managers, and corporations are the main
participants in OTC derivatives markets
§ Trades are usually between two financial institutions or between a financial institution and
one of its clients (typically a corporate treasurer or fund manager).
§ Financial institutions (large banks) act as market maker (quote bid and ask price).
§ Non-standardized contract
negotiate mutually attractive deal.
§ Credit risk.

HOW DERIVATIVES ARE USED?
v To hedge risks
v To speculate (take a view on the future direction of the market)
v To lock in an arbitrage profit
v To change the nature of a liability
v To change the nature of an investment without incurring the costs of selling one portfolio and
buying another
15
FORWARD CONTRACTS
v Spot contract: agreement to buy / sell an asset today.
v Forward contract: agreement to buy/sell an asset at specified time in the future for a certain
price.
v Traded in OTC market.
§ Long position: the party that agrees to buy.
§ Short position: the party that agrees to sell.
v Popular on foreign exchange forward contracts
16
FORWARD CONTRACTS
v Forward price: the delivery price that would be applicable to the contract that negotiated
today.
v It is the delivery price that would make the contract worth exactly zero today.
v The forward price may be different for contracts of different maturities.

FORWARD CONTRACTS
v Example: Long and Short position
On May 21, 2020, the treasurer of a corporation enters into a long forward contract to buy £1
million in six months at an exchange rate of 1.2230 $/£. This obligates the corporation to pay
$1,223,000 for £1 million on November 21, 2020.
The bank has a short forward contract on GBP. On November 21, 2020, it will sell £1 million for
$1.2230 million.
Both sides have made a binding commitment.
What are the possible outcomes at the end of the 6 months?
What if the spot exchange rate rose to 1.3000?
What if the spot exchange rate fell to 1.2000?
18
FORWARD CONTRACTS
v Example: Long and Short position
What are the possible outcomes at the end of the 6 months?
§ Payoff from a long forward position = ST – K.
§ Payoff from a short forward position = K – ST.
§ ST: spot price at maturity.
§ K: delivery price.

FORWARD CONTRACTS
v An Arbitrage Opportunity?
Example: Suppose that:
The price of a non-dividend-paying stock is $60
The 1-year US$ interest rate is 5% per annum
Is there an arbitrage opportunity if:
a. The 1-year forward price of the stock is $67
b. The 1-year forward price of the stock is $58
21
FORWARD CONTRACTS
v An Arbitrage Opportunity? - The Forward Price of a Non-Dividend Paying Stock
If the spot price is S and the forward price for a contract deliverable in T years is F, then
F = S (1+r )T
where r is the 1-year (domestic currency) risk-free rate of interest.
In our examples, S = 60, T = 1, and r = 0.05 so that
F = 60(1+0.05) = 63
22
FUTURES CONTRACTS
v Futures contract: agreement to buy or sell an asset at a certain time in future for a certain
price.
v Similar to forward contract, but traded on an exchange.
v Standardized contract.
v Margin requirement.
Example: Agreement to:
§ Buy 100 oz. of gold @ US$1800/oz. in December
§ Sell £62,500 @ 1.2500 US$/£ in March
§ Sell 1,000 bbl. of oil @ US$40/bbl. in April

OPTIONS
v An option is a financial security that gives the holder the right to buy or sell a specified
quantity of a specified asset at a specified price on or before a specified date.
v The price in the contract is known as the exercise price or strike price.
v An American option can be exercised at any time during its life.
v A European option can be exercised only at maturity.
v Traded on both OTC and exchange markets.
v Most of the options that are traded on exchanges are American.
26
OPTIONS
v A call option is an option to buy a certain asset by a certain date for a certain price (the strike
price)
v A put option is an option to sell a certain asset by a certain date for a certain price (the strike
price)
v Buyer / holder / long position: has the right.
§ Pay premiums.
§ Buy a call = long a call.
v Seller / writer / short position: has the obligation.
§ Receive premiums.
§ Sell a call = write a call = short a call.
Ø Long call: right to buy.
Ø Short call: obligation to sell.
Ø Long put: right to sell.
27
Ø Short put: obligation to buy
