A concept that involves offsetting a risk position. In the commodities trade, it might involve a processor position or a speculative position. For example, a potato chip manufacturer can hedge or protect a profit margin on a large order of chips to be delivered in the future by buying potatoes in the futures market; a potato farmer may sell the futures contract to the process to protect some or all of his or her investment in raising his or her crop. A speculator in potato contracts might hedge a long position in old crop futures by selling new crop futures in anticipation of a bumper crop and, therefore, lower prices. Arbitrage is a type of hedge involving the buying of securities in one market and selling in another market when the price difference between markets offers a profitable trade. Hedged trades are used in the stock option market where the various positions are referred to as spreads, straddles, etc. In securities trading and investment, selling short is used to hedge stock ownership positions against a decline in the general market.
