金程問(wèn)答沖刺筆記中上冊(cè),177頁(yè)寫了top down屬于基本面分析法,這句話是不是有問(wèn)題,也可以用宏觀指標(biāo)建模的方式進(jìn)行top down的行業(yè)篩選?top down 和bottom up都可以既屬于基本面也可以屬于量化;factor based僅是屬于量化分析對(duì)吧?activist 僅屬于基本面?
老師,b選項(xiàng),package不是也會(huì)導(dǎo)致組合的股票數(shù)量大于指數(shù)的股票數(shù)量嗎
R16, PPT第38頁(yè),請(qǐng)問(wèn)yield“high div yield stocks may provide higher excess return in low interest rate”怎么理解?
best risk-efficient delivery of results,是指active return/active risk最大嗎
老師,這道題題目問(wèn)的是excess return(需要考慮retrun與risk-free retuen),但為什么答案解析里用的確是active retuen的計(jì)算方法(與benchmark比較)?
該題第三題該怎么解?
為啥大市值全買?因?yàn)槌煞止傻臄?shù)量少嗎?謝謝
老師,原版書R17example 4的第二問(wèn)能否解答下?

老師,79,謝謝
對(duì)于benchmark agnostic manager,目標(biāo)active risk6-10%,那不應(yīng)該超出benchmark的風(fēng)險(xiǎn)嗎,后面絕對(duì)風(fēng)險(xiǎn)為何又是index的85%,反而比benchmark風(fēng)險(xiǎn)小了?
平安和同仁堂的例子中,她們的相關(guān)性低,variance應(yīng)該低吧?
請(qǐng)問(wèn)這個(gè)case的第1小題,對(duì)應(yīng)材料中的the technique used to construct the new index portfolio assumes that the factors used to explain stock returns are uncorrelated對(duì)解題起了什么作用?
