The Nature of Derivatives
A derivative is an instrument whose value depends on the values of other more basic underlying variables

Derivatives Markets Exchange traded
Traditionally exchanges have used the open-outcry system, but increasingly they are switching to electronic trading
Contracts are standard there is virtually no credit risk
Over-the-counter (OTC) A computer- and telephone-linked network of
dealers at financial institutions, corporations, and fund managers
Contracts can be non-standard and there is some small amount of credit risk

Ways Derivatives are Used
To hedge risks To speculate (take a view on the
future direction of the market) To lock in an arbitrage profit To change the nature of a liability To change the nature of an investment
without incurring the costs of selling one portfolio and buying another

Forward Contracts
Forward contracts are similar to futures except that they trade in the over-the-counter market
Forward contracts are particularly popular on currencies and interest rates

Forward Price
The forward price for a contract is the delivery price that would be applicable to the contract if were negotiated today (i.e., it is the delivery price that would make the contract worth exactly zero)
The forward price may be different for contracts of different maturities
![Page 10: Chap 1](https://reader034.fdocuments.us/reader034/viewer/2022052412/558535a7d8b42a9b388b527f/html5/thumbnails/10.jpg)

Example (page 4)
On June 3, 2003 the treasurer of a corporation enters into a long forward contract to buy £1 million in six months at an exchange rate of 1.6100
This obligates the corporation to pay $1,610,000 for £1 million on December 3, 2003
What are the possible outcomes?

The Forward Price of Gold
If the spot price of gold 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 = 300, T = 1, and r =0.05 so that
F = 300(1+0.05) = 315

Types of Traders
• Hedgers
• Speculators
• Arbitrageurs
Some of the largest trading losses in derivatives have occurred because individuals who had a mandate to be hedgers or arbitrageurs switched to being speculators (See for example Barings Bank, Business Snapshot 1.2, page 15)
![Page 28: Chap 1](https://reader034.fdocuments.us/reader034/viewer/2022052412/558535a7d8b42a9b388b527f/html5/thumbnails/28.jpg)

Hedging Examples (pages 10-11)
A US company will pay £10 million for imports from Britain in 3 months and decides to hedge using a long position in a forward contract
An investor owns 1,000 Microsoft shares currently worth $28 per share. A two-month put with a strike price of $27.50 costs $1. The investor decides to hedge by buying 10 contracts

Speculation Example
An investor with $4,000 to invest feels that Amazon.com’s stock price will increase over the next 2 months. The current stock price is $40 and the price of a 2-month call option with a strike of 45 is $2
What are the alternative strategies?
