One well-known strategy is the covered call, in which a trader buys a stock
(or holds a previously-purchased long stock position), and sells a call. If
the stock price rises above the exercise price, the call will be exercised
and the trader will get a fixed profit. If the stock price falls, the call
will not be exercised, and any loss incurred to the trader will be partially
offset by the premium received from selling the call. Overall, the payoffs
match the payoffs from selling a put. This relationship is known as put-call
parity and offers insights for financial theory. A benchmark index for the
performance of a buy-write strategy is the CBOE S&P 500 BuyWrite Index (
ticker symbol BXM).
