Forwards, futures swaps and options WORKBOOK By Ramon Rabinovitch
The Nature of Derivatives A derivative is a financial instrument whose value depends on the values of other more basic underlying variables In particular, it depends on the market price of the so called: underlying asset.
Underlying assets: Stocks Bonds Foreign currencies Gold, Silver… Crude oil, Natural gas, Gasoline, heating oil… Wheat, corn, rice, grain feed, soy beans, pork bellies… Stock indexes
DERIVATIVES ARE CONTRAC TS: FORWARDS FUTURES OPTIONS SWAPS
WHY TRADE DERIVATIVES? THE FUNDAMENTAL REASON FOR TRADING DERIVATIVES IS TO HEDGE: THE PRICE RISK (VOLATILITY) Exhibited by the spot price of the underlying commodity
PRICE RISK IS THE VOLATILITY ASSOCIATED WITH THE COMMODITY’S PRICE IN THE CASH MARKET REMEMBER THAT THE CASH MARKET IS WHERE FIRMS DO THEIR BUSINESS. I.E., BUY AND SELL THE COMMODITY. ZERO PRICE VOLATILITY NO DERIVATIVES!!!!
PRICE RISK: At time t, the asset’s price at time T is not known. Probability distributio ST St t T time
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
Types of risk: Price risk Credit risk Operational risk Completion risk Human risk Regulatory risk Tax risk
IN THIS CLASS WE WILL ONLY ANALYZE THE RISK ASSOCIATED WITH THE SPOT MARKET PRICE OF THE UNDERLYING ASSET
DERIVATIVES ARE CONTRACTS: Two parties Agreement Underlying security Contract termination date
DERIVATIVES ARE CONTRACTSThe distinction is made by the different stipulations of the contract Forwards and Futures are Fixed obligations A FORWARD IS A CONTRACT IN WHICH ONE PARTY COMMITS TO BUY AND THE OTHER PARTY COMMITS TO SELL A SPECIFIED AMOUNT OF AN AGREED UPON COMMODITY FOR A PREDETERMINED PRICE ON A SPECIFIC DATE IN THE FUTURE.
Delivery and payment Buy or sell a forward t T Time BUY = OPEN A LONG POSITION SELL = OPEN A SHORT POSITION
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
EXAMPLE: GBP 18.5.99 SPOT USD1,6850/GBP 30 days forward USD1,7245/GBP 60 days forward USD1,7455/GBP 90 days forward USD1,7978/GBP 180 days forward USD1,8455/GBP The existence of forward exchange rates implies that there is a demand and supply for the GBP for future dates. In the actual market, however, different rates are quoted for buy (ask) and for sell (bid) orders.

Futures Contracts • Agreement to buy or sell an asset for a certain price at a certain time • Similar to forward contract • Whereas a forward contract is traded OTC, a futures contract is traded on an exchange
AN OPTION IS A CONTRACT IN WHICH ONE PARTY HAS THE RIGHT, BUT NOT THE OBLIGATION, TO BUY OR SELL A SPECIFIED AMOUNT OF AN AGREED UPON COMMODITY FOR A PREDETERMINED PRICE BEFORE OR ON A SPECIFIC DATE IN THE FUTURE. THE OTHER PARTY HAS THE OBLIGATION TO DO WHAT THE FIRST PARTY WISHES TO DO. THE FIRST PARTY, HOWEVER, MAY CHOOSE NOT TO EXERCISE ITS RIGHT AND LET THE OPTION EXPIRE WORTHLESS. A CALL = A RIGHT TO BUY THE UNDERLYING ASSET A PUT = A RIGHT TO SELL THE UNDERLYING ASSET

A SWAP IS A CONTRACT IN WHICH THE TWO PARTIES COMMIT TO EXCHANGE A SERIES OF CASH FLOWS. THE CASH FLOWS ARE BASED ON AN AGREED UPON PRINCIPAL AMOUNT. NORMALLY, ONLY THE NET FLOW EXCHANGES HANDS. Principal amount = EUR100,000,000; semiannual payments. 7% Party B Party A 6-months LIBOR
Types of Derivatives Traders • Speculators • Hedgers • Arbitrageurs Some of the large trading losses in derivatives occurred because individuals who had a mandate to hedge risks switched to being speculators
THE ECONOMIC PURPOSES OF DERIVATIVE MARKETS HEDGING PRICE DISCOVERY SAVING HEDGING IS THE ACTIVITY OF MANAGING PRICE RISK EXPOSURE PRICE DISCOVERY IS THE REVEALING OF INFORMSTION ABOUT THE FUTURE CASH MARKET PRICE FOR A PRODUCT. SAVING IS THE COST SAVING ASSOCIATED WITH SWAPING CASH FLOWS
