期权(option)又称为选择权,是在期货的基础上产生的一种衍生性金融工具。是指在未来一定时期可以买卖的权力,是买方向卖方支付一定数量的金额(指权利金)后拥有的在未来一段时间内(指美式期权)或未来某一特定日期(指欧式期权)以事先规定好的价格(指履约价格)向卖方购买或出售一定数量的特定标的物的权力,但不负有必须买进或卖出的义务。从其本质上讲,期权实质上是在金融领域中将权利和义务分开进行定价,使得权利的受让人在规定时间内对于是否进行交易,行使其权利,而义务方必须履行。在期权的交易时,购买期权的一方称作买方,而出售期权的一方则叫做卖方;买方即是权利的受让人,而卖方则是必须履行买方行使权利的义务人。
