※ 引述《Latte7 (nonono)》之銘言:
: 目前聯準會五月幾乎篤定升兩碼
: 六月有很高機率一次升三碼
: 想請問板上高手
: 雖然這幾乎是已知資訊
: 那做空美國國債是否還有利可圖(買進TMV)
: 或是市場已經完全反映?
: 謝謝
關於 priced in 這件事,考慮一個例子:
假設市場預測,一個月後有60%會升3碼,有40%升2碼
並假設市場對機率的預測是正確的
從而市場價格落在升2.6碼 (姑且直接用算數平均)
某人在沒有額外有效資訊的狀況下,閉著眼睛下注賭會升3碼
結果一個月後,真的升了3碼,賺了一筆
這並不代表一個月前,市場價格落在2.6碼是沒有完全反映
只是市場priced in的某些機率並沒realized
===
當只能觀察realized的結果時
有時很難斷定,到底是市場沒有完全反映
或者只是某些被priced in的機率沒有現身
===
Omicron導致市場下跌,是因為市場過度恐慌?
或者只是運氣好,Omicron剛好死亡率很低
在某些平行宇宙,2021年11月的新變種,是比Delta更容易傳染且死亡率更高的病毒?
市場正確的 priced in 了風險,只是風險沒有現身?

You got to know when to hold 'em, know when to fold 'em, Know when to walk away and know when to run.
You never count your money when you're sittin' at the table. There'll be time enough for countin' when the dealin's done.
'Cause ev'ry hand's a winner and ev'ry hand's a loser, And the best that you can hope for is to die in your sleep."
now Ev'ry gambler knows that the secret to survivin' Is knowin' what to throw away and knowing what to keep.
