18. © John A. Dutton October 2004 Option The right, but not the obligation, to execute a specified trade for a fixed price before a future date or to assume a position in a futures contract. (Option on a futures contract, option on a stock, ‘option’ on a weather variable…) A call is the right to buy, a put the right to sell. Contingent contracts specify a quantity, a price, and an expiration or settlement date. Options are also derivatives, and in some cases, second derivatives.
