老师好 这题知道bull call spread 是buy call at low call price and sell call at high call price.
打亮这句是说 implied volatility of the call option with the strike price =32 is the highest among the three 是指当执行价为32时候的call option 的波动率最高 , 是吗?
不是波动率高我们要long? 就像认为 volatility高的时候我们去long straddle,为啥不选B (long 一个volatility 高的 long call at X=32,再short call at X=33)?谢谢。
