能全部具體講一下對沖基金suffer的bias么，記得之前有題是說對沖基金peer group benchmark什么的東西，能在說說對沖基金benchmark的知識點(diǎn)么
第2問，回答準(zhǔn)備manager universe可以嗎？講義中關(guān)于manager selection的步驟，除了qualitative和quantitative analysis，第一步是manager universe
R27第40題不是很理解，是不是只有在gross return=breakeven active return，也就是1.25的時候，total fee就是0.35，其他情況下都要收sharing的部分。麻煩也解釋下什么是breakeven active return，為什么只有在這個情況下不收sharing的部分
第一題為啥不能用 price target benchmark呢
老師這個題的題意怎么理解？
請問return-based是top-down approach？holding-based是bottom-up approach？為什么？
C is correct because if we measure the correlation between active management return, A = (P ? B), and style return, S = (B ? M), we can identify whether the manager’s active selection decisions align with the style currently favored by the market. A good benchmark should not reflect these systematic biases, as indicated by the correlation between A and S not being statistically different from zero. 這一段能否解釋一下
這個題目到底在問什么呢，老師講先寫結(jié)論，結(jié)論是什么？
short call不應(yīng)該是無限損失嗎，怎么是一條平行直線，而且這也不是單純的call structure了吧

第四題為什么allocationeffect沒有算interaction?
老師第二題，公開市場交易包括哪些？
請問Reading 36 課後練習(xí)題中 "18. Which of the following fee structures most likely decreases the volatility of a portfolio's net returns?" A. Incentive fees only B. Management fees only C. Neither incentive fees nor management fees 解答是 A is correct. Because incentive fees are fees charged as a percentage of returns (reducing net gains in positive months and reducing net losses in negative months), its use lowers the standard deviation of realized returns. Charging a management fee (a fixed percentage based on assets) lowers the level of realized return without affecting the standard deviation of the return series. 請問當(dāng) Portfolio's returns turn negative 是收不到 incentive fees 的，如何reducing net losses in negative months?
這怎麼是bull spread？？題目是call option 那hidden lake畫出來就是個call option啊？？
