Call Options
A Call option is a contract that gives the buyer the right to buy 100 shares of an underlying equity at a predetermined price (the strike price) for a preset period of time. The seller of a Call option is obligated to sell the underlying security if the Call buyer exercises his or her option to buy on or before the option expiration date. |
