同学你好,以下是原版书原文:.When the VIX futures curve is in contango (backwardation) and assuming volatility expectations remain unchanged, the VIX futures price will get “pulled” closer to the VIX spot price, and they will decrease (increase) in price as they approach expiration. 当VIX 期货是contango时,就意味着F>S,但是当期货到期时,future price和spot price是要趋同的,这回导致VIX future的价格下跌。因此本题中,VIX future处于contango,意味着F>S,future price在临近到期时会逐渐下降并向spot price靠近。所以这里要防范的其实是VIX future price下跌,于是trader 2就不对了,应该要long put option on VIX futures

1.老师好,所以是这句“"HE believe investor are complacent as reflected in the historically low level of VIX" 说明了 “assume volatility unchanged"的意思吗? 然后就可以把VIX当作一个普通forward, 到期的时候forward price 会向spot 收敛。
2.另外如果波动率是会变的话,put on vix 也是波动下降赚钱把
