MR P E 公式如何推断的？

图上哪条线代表价格？价格在哪个位置行权？

原版书上这句话看不懂，allows volatility sellers to sell variance swaps at a higher price than at-the-money options，这个跟atm option有什么关联？A feature of variance swaps that makes them particularly interesting to investors is that their payoffs are convex in volatility, as seen Exhibit 4. This convexity occurs because being long a variance swap is equivalent to be long a basket of options and short the underlying asset (typically by selling a futures contract). A long position in a variance swap is thus long gamma and has a convex payoff. This characteristic allows volatility sellers to sell variance swaps at a higher price than at-the-money options because the swap’s convex payoff profile is attractive to investors who desire a long volatility position as a tail risk hedge.

第一题能再讲解下么，不太懂

疑问在答案，我看有的老师回复“保底是核心特征，封顶算完善补充”，那答案写为“Carpenter management has a bonus-style fee with minimum and maximum fee feature that are close equivalent of a manager's call option on a share of active return”，这样是不是更准确？

股利支付率这个DPS除以EPS怎么理解啊，老师能不能拆解推导一下

EPS乘股利支付率怎么理解，我写的是DID/NI乘以NI-DID/普通股股数，要的应该是DID/总股数把！

Q2在哪个知识点，上课的时候好像没有提到过，另外可以看一下这个知识点在冲刺笔记哪页？

老师讲解的时候提到，如果alpha比较大，就不是量化模型，是依靠主观判断进行选股。那通常要多大的activerisk或者activeshare才会认为是alpha比较大呢

如果有是standardfeepaying，又是受益人，那还需要最后再交易吗
