补充资料:欧洲式期权、美国式期权与亚洲式期权
欧洲式期权、美国式期权与亚洲式期权
【欧洲式期权、美国式期权与亚洲式期权】期权合约所规定的权利有一定的时效期,过了失效日后,权利即行作废。一些期权规定权利仅能在有效期的最后一天执行,这种期权被称为欧洲式期权(ell功pean叩tions);另一些期权则容许在有效期内任何一天执行,这种期权被称为美国式期权(一~oPtions)。值得指出的是,虽名为欧洲式或美国式期权,但已无任何地理上的意义。由于欧洲式期权的规定过于严格,又出现了一种“改变的欧洲式期权”,它允许期权在一定的时间范围内进行交易。可见,美国式期权为期权购买者提供了更多的选择机会,因此,它的购买者也往往需支付更高的保险费。近年来无论在欧洲或美国,所交易的期权均以美国式为主,欧洲式期权虽仍存在,但其交易量已比不上美国式期权。 在so年代末期,市场上又出现了一种所谓亚洲式期权(asian ontions),但也无地理上的意义,其差别主要在于履约价值(exe而sev公此)的计算。以买权为例,无论是美国式期权或是欧洲式期权,执行权利所能得到的履约价值均为当时标的物的市价减去履约价格,再乘以合约所定的数量,但亚洲式期权的履约价值则为权利期间内标的物市价的平均(计算至履约日为止),减去履约价格,再乘以合约所定的数量。
