R25原版書Example 8-Macro attribution這個題目，標黃的兩個數(shù)據(jù)是怎么來的，計算過程可以列示一下嗎？
老師您好，課后題172頁13題，bond index is not investable. 但是講義中broad market index is investable, 這兩者有什么不同？
請問官網(wǎng)題25的圖中箭頭處的分母，為什么股數(shù)10,000前面沒有負號？而此前計算IS時（也就是分子各項）卻在股數(shù)前使用了負號
老師，這題是因為是賣出股票，所以才選cost最大的嗎？如果是買入股票的話，是不是opportunity cost(為零)才是最favorable的？
micro 或macro attribution analysis都是用bf模型嗎
怎么分別理解price benchmark ，trading strategy和trade algorithm？第10和11題都是考慮的arrive price，12題又選liquidity seeking，有點懵
Trading 課后題 reading 26 第2題，怎么看出來是對比了benchmark？
老師，這一題和R27課后題40題是一樣的，之前提問過說是題目有問題，但還沒看到有勘誤，官網(wǎng)題又有，所以到底是題目有問題嗎？
這個例子講義上答案解析說基金經(jīng)理對小市值股票有微小敞口，這句話不明白，benchmark 中市值因子前面的系數(shù)是-1,portfolio 中的系數(shù)是-1.05，不是說明portfolio更偏向大盤股一點點嗎？
官網(wǎng)題：While the buy-side trader executes the BYYP trade, Harding and Yellow review ValleyRise's trade policy document. After reviewing the document, Yellow recommends several changes: 1) add a policy for the treatment of trade errors; 2) add a policy that ensures over-the-counter derivatives are traded on venues with rules that ensure minimum price transparency; and 3) alter the list of eligible brokers to include only those that provide execution at the lowest possible trading cost. Q. As it relates to the trade policy document, ValleyRise should implement Yellow's recommendation related to: A. the list of eligible brokers. B. a policy for the treatment of trade errors. C. a policy for over-the-counter derivatives trades. 這道題請問A和C為什么不對？
這道題確實非常confusing，我看了半天沒搞懂 investing in new investment和 investing with maximum flexibility哪個是不斷evolve的，我判斷是mm更適合因為new?investment應(yīng)該是更不能predict的啊
老師，答案里說這個fixed income 是有benchmark的，題目里沒見到有提及啊，怎么就判斷出它是有benchmark的呢？
老師，我覺得第一個是投資新主題，風險更大，第二個尋找錯誤定價，確定性更大才對。
R25的case1第2問為什么不選A:factor framework ? 文中說“Bragg notes that the fixed-income portfolio manager has strong views about the effects of macroeconomic factors on credit markets and follows a top-down investment process.”
課后題186頁42題v的優(yōu)點可以寫成本低嗎？p的優(yōu)點可以寫value added potential嗎
