※ 引述《NSeven (小七)》之銘言:
: 過了一個月 來更新一下狀況
看到N大拋磚引玉 鍵盤經濟學家的小弟決定也來分享我在一些論文上看到的有趣數據
Brad Barber 跟 Terrance Odean 是兩個專門研究散戶交易的知名學者
他們為了研究是否有投機的能力這回事 找了某個國家的學者合作並取得該國的資料
和世界上絕大部分國家不同 該國非常鼓勵當沖 (day trade) 這樣的行為
究其原因可能是因為股市非常淺碟 缺乏交易量和流動性的緣故吧
但那又是另外的故事了 這邊先不提
因為該國股市鼓勵當沖的緣故 這樣的環境特別適合研究究竟存不存在投機能力這回事
畢竟當沖行為不會受到基本面影響 就是單純的投機行為 (speculation)
讀到這裡 大家應該都看得出來 他們研究的這個國家就是台灣
他們這系列的研究發表得很不錯 有發在三大期刊的RFS上 也有JFM和RAPS這些頂級的B刊
那他們究竟發現了什麼呢?
在JFM的那篇文章中 他們發現在1992到2006年的15年間
超過46萬位進行當沖交易的散戶中 只有不到4千人(1%比例) 能夠持續賺到正的超額報酬
任一年有正的超額報酬的比例其實有超過2成 但連續兩年正的報酬就不到1%了
這還是不考慮證交稅和手續費的情況下
但是是否真的有投機能力這回是呢? 在這穩定持續賺到正的超額報酬的4千人中
前5百名的當沖交易者平均每天可以賺到61bps (0.61%) 的超額報酬
扣除證交稅和手續費也有相當於每天38bps (0.38%) 的超額報酬
的確是非常可觀
所以問題就是 大家覺得自己是否是那前5百名或前4千名呢?
順帶一提 在RFS上那篇文章 他們發現 台灣的散戶 不論是否是當沖
他們每年平均交易賠掉3.8%的報酬 (-3.8%的超額報酬)
損失的金額相當於台灣一年2.2%的GDP
只能說 祝福N大就是那其中能賺到錢的前4千名奇才
