Functions of futures market n n Three groups of futures market users: n Speculators who wish to make lots of money. n Hedgers who wish to avoid losing lots of money. n Arbitragers who wish to make easy money by ‘price-discovery’. Futures market provides risk-sharing, liquidity, and information. 5
Speculation - idea n n n You believe that floods in Iowa will reduce soybean yields and hence soybean price would rise in Nov. How can you profit from this scenario? Bet on soybean prices to rise - long futures Today: buy Nov Bean at $5. 58; later: sell Nov Bean to offset. If price goes up, you profit. But you also bears the risk that price may decline as well. Why not speculate in spot market? 6
Speculation - example n n A speculator buys (takes a long position in) 1 Aug contract on July 1 st at $942. 10, pay initial margin $6, 500. contract size is 100 troy ounces , it has a market value of $94, 210. You are paying ($6, 500/94, 210 = 6. 9%) of contract value. Scenario 1: If Gold contract goes up to $960 by end of July, then: n n n Profit = ($960 - $942. 10)*100 = $1790 Return = $1790/$6500 = 27. 5% Scenario 2: If Gold contract goes down to $930. 00 by end of July, then: n n Profit = ($930 - $942. 10)*100 = - 1210 Return = - 1210/6500 = -18. 6% 7
Hedging - idea n n People who would sell or buy commodities in the future could hedge price risk by holding positions in futures markets. Why? n n spot price and futures price move together offset lock in selling (purchase) price in advance Short hedgers: e. g. farmers Long hedgers: e. g. processors 8
Short hedge - example n n A farmer who has an agriculture commodity to sell in the future will be hurt by a price decline in the future. Hedging: profit from the futures market whenever lose from the cash market. Risk in spot market is offset by trading in futures market. 9
Short hedge - example n n Suppose lean hogs are now trading at $70 (per 100 pounds) in spot market. A farmer is afraid that in Aug when he is ready to sell the hog, he would not be able to sell at this good price. Step 1: Look at futures quote to find out Aug Lean Hogs futures contracts are trading at $70. 75 in Chicago Mercantile Exchange. Step 2: Call broker and place order to sell 1 Aug Lean Hogs contract and send margin money.
Short hedge example n n n It is now August and the farmer is ready to sell hogs to the packer. Scenario 1: Aug Lean Hogs trading at $74. 00, loss ($70. 75 - $74. 00 = -$3. 25 per 100 lb. ) in futures market. In spot market, sell hog at a high price of $74. 00 ($4 up). Scenario 2: Aug Lean Hogs trading at $65. 25, gain ($70. 75 - $65. 25 = $5. 5 per 100 lb. ) in futures market. Sell hog in spot market at a low price of $65 ($5 down).
