原版书V4 第34 -35 页这句话怎么理解 Because stock gamma is always zero, the convertible arbitrage strategy will leave the convertible arbitrageur “synthetically” longer in total equity exposure as the underlying security price rises and synthetically less long as the equity price falls.

同学,上午好。
股票没有gamma,但option有gamma,那么long convertible bond=long pure bond+long call on stock,同时short stock,整个组合的gamma为正,而gamma类似于凸性,所以组合有涨多跌少的特点。股票涨起来就行权,股票跌了,就不行权,赚债券的收益。
