问题如下:
A delta-neutral position exhibits a gamma of –3,200. An existing option with a delta equal to 0.5 exhibits a gamma of 1.5.Which of the following will generate a gamma-neutral position for the existing portfolio?
选项:
A. Buy 2,133 of the available options.
Sell 2,133 of the available options.
C.Buy 4,800 of the available options.
Sell 4,800 of the available options.
解释:
为了创建一个gamma中性头寸,经理必须增加适当数量的期权,使其等于现有投资组合的gamma头寸。在这种情况下,现有的gamma头寸是-3200,一个可用期权的gamma是1.5,这相当于购买大约2133份期权(= 3200 / 1.5)
加入了delta=0.5的option之后是不是又不再是delta neutral了?
