2023-09-26 14:32這個(gè)18題老師的講解和標(biāo)準(zhǔn)答案差別太大了。標(biāo)準(zhǔn)答案是說shorting stock using delta headge ratio. because they are exposed to changes in the hedge ratio, they are said to be long gamma. They are also exposed to changes in the price volatility of the stock underlying the option embedded, so they are said to be long vega老師能解釋一下這個(gè)標(biāo)準(zhǔn)答案是什么意思么。

同學(xué)你好,這部分你可以看講義理解。long convertible 本質(zhì)就是long 了風(fēng)險(xiǎn)因子,這些風(fēng)險(xiǎn)因子中部分可以通過short手段進(jìn)行對沖(對于duration,delta可以對沖至中性分別通過short treasury and short stock(解析中的shorting stock by using delta hedge ratio,就是說用stock short的手段,對沖delta這一風(fēng)險(xiǎn)因子至中性;這時(shí)我們就剩下gamma 和vaga因子了,通過這兩個(gè)風(fēng)險(xiǎn)因子進(jìn)行套利)),因此說這個(gè)策略也叫net long gamma and vega strategy
