這句話還是沒有理解在說啥，可以麻煩講一下嗎
為什么intraday不合適
這個題答案怎么寫
duration和curve_effect這里沒太懂，前者小于0，說明超配長期bond，bet利率下降不對，利率實際上應(yīng)該上升了。后者大于0，說明長短期bond之間的配置是正確的，而超配長期帶來了正的curve_effect，說明長期利率雖然上升，但比短期程度小，變得flat了。所以就是長期的沒配置好，但短期更差，那就兩者都不咋行唄，是這個意思嗎？沒太搞明白
老師，能否解釋一下R26 第1題，第2題。關(guān)于業(yè)績歸因，不是為了對基金經(jīng)理的分析質(zhì)量評判嗎？另外，第2題固定收益的業(yè)績歸因為啥不選A？謝謝
為什么不是dark pool
R25 第22題，為什么decision price是23.01，不是market open price$22.15，或pre- market price $20.34呢？既然在交易前就認(rèn)為是overvalued，那這個應(yīng)該是decision price吧？ 然后第23題，計算Arrival Cost，P0為啥又是$23.09？P0應(yīng)該用開盤價吧？
請講下此題，沒看懂答案

老師，Mock2下午第30題答案解析中的(i.e., positively skewed strategies, such as trend following) and (i.e., negatively skewed strategies, such as option writing)怎么理解？謝謝
精 Trading，沖刺筆記 129頁，A good benchmark should not reflect these systematic biases, where the correlation between A and S should not be statistically different from zero。 A，S 相關(guān)性系數(shù)=0. 這句英文“A and S should not be statistically different from zero”是指相關(guān)還是不相關(guān)?
CFA 網(wǎng)站上有道題計算opportunity cost: Morrison has been working on executing a sell order to liquidate shares in Acme Industrials (ACME). The closing price on Tuesday was $79.90. Morrison received the order from Wright before the market open on Wednesday morning to sell 50,000 ACME shares with a day limit of $80.00. No part of the order is filled on Wednesday, and the stock closes the day at $79.60. On Thursday morning, Morrison instructed a new day order to sell the 50,000 shares at $79.50; 30,000 shares were sold at $79.50 per share, with resulting commissions and fees for the trade of $0.02 per share. Shares for ACME closed the day Thursday at a price of $79.40 per share. No further attempts were made to sell the unfilled 20,000 shares, which were canceled. 答案是 Opportunity cost = 50,000 – 30,000 = 20,000 × ($79.90 – $79.50) = $8,000. 我覺得是錯的，應(yīng)該是 (79.9-79.4)*20,000 是 決策價格和收盤價的差價。
