我之前看過這個影片
覺得印象很深刻
https://youtu.be/z2oQe6B1Qa4?t=1885
從上面影片這個時間開始往後約20分鐘
Andrew Lo在講 現實中 如果大盤在迅速下跌的狀況
你不可能找到一個跟大盤呈現negative correlation的股票
那我幫大家整理一下這個20分鐘影片在講啥
Lo想傳達的是
如果股市在嚴重往下走的階段
你要找到一個還能賺錢的股票就意味他和其他股票的correlation是負的
Lo的結論是這是不可能的一件事情
因為如果大盤再跌
你又能發現一個股票是和大盤呈現負關聯性的
那大家就會瘋狂去買它
造成它的未來預期價格變高
但這會壓縮預期報酬率
所以就算有這麼一個負關聯度的股票
那它很快(一天甚至幾小時內內)也會從負的變成正的關聯度
然後影片有講 空(short) 不符合他要找的負關聯度股票的定義
這邊有人有辦法挑戰Andrew Lo的看法的嗎?
我自己的看法
負關聯度有點像是在找一個負折射率或是比光速傳播還快的介質
大家的看法?
