视频中老师说,期限长的期权对二阶导更敏感也就是对gamma 最敏感,期限短的期权对一阶导也就是delta 更敏感,但是原版书上不是这样说的,而是另一种说法“In terms of expiry, the longer-dated options will have more absolute exposure to volatility levels (i.e., vega exposure) than shorter-dated options, but the shorter-dated options will exhibit more delta sensitivity to price changes (i.e., gamma exposure).” 到底这里是在说什么,烦请老师解释一下
