A put option is a contract that gives the option holder the right, but not obligation, to sell a set amount of shares (100 shares per contract) at a set price. If the option is exercised, the option writer must purchase the shares from the option holder. The opposite of a put option is a call option, which gives the holder the right to purchase a set amount of shares at a set price. Whether a put or a call option, however, the option holder can exercise or act on the contract at any time (American option) until its expiration date.
