Three Reasons for Trading Derivatives: Hedging, Speculation, and ArbitrageHedge funds trade derivatives for all three reasons (See Business Snapshot 1.1) When a trader has a mandate to use derivatives for hedging or arbitrage, but then switches to speculation, large losses can result. (See Barings, Business Snapshot 1.2)Fundamentals of Futures and Options Markets, 6th Edition, Copyright John C. Hull 2007

Hedging Examples (Example 1.1 and 1.2,page 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

1.27

The Futures Price of GoldIf the spot price of gold is S & the futures price is for a contract deliverable in T years is F, then F = S (1+r )T where r is the 1-year (domestic currency) riskfree rate of interest. In our examples, S=600, T=1, and r=0.05 so that F = 600(1+0.05) = 630
