risk reversal如果没有标的物的话only buy put option and write call option 根据图像 标的价格上升期权价值会一直下降 lose upside protection,所以讲义里为什么说the upside is limited to the strike price?

同学,上午好。
risk reversal = long OTM call + short OTM put
这里long OTM put + short OTM call是short risk reversal。
因为short OTM call,如果股价上涨到call 的行权价,对方会行权,我们把股票(初始标的资产)卖给对方,那么之后上涨就与我们无关的,所以the upside is limited to the strike price
