臺灣博碩士論文加值系統

本研究以國內某券商提供民國八十七年一月至民國九十年九月共52,649個帳戶交易普通股的記錄為研究對象，探討台灣證券市場散戶的交易行為以及投資績效。資料顯示樣本期間平均家計單位的毛報酬以及淨報酬與大盤的走勢幾乎成一致的脈動，與大盤表現沒有太大的不同。
由資料中我們得知投資人傾向握有高市場風險（市場β值均顯著大於1）以及成長型的股票(HML係數均顯著為負)，公司規模大小則非投資人在挑選股票時的主要考量因素(SMB係數均不顯著)。
研究結果顯示，若依投資的交易頻率分成五群，不頻繁交易的投資人表現最好，最頻繁交易的投資人次之。周轉率最低的投資人屬於『Holding Trading』的交易策略，不隨便交易，節省頻繁買賣所必須支出的大量交易成本。而周轉率最高的投資人其優異表現可能是來自於這群投資人相較於其他人掌握了更多有用的資訊而做出正確的交易判斷，或者是即使面對相同雜亂的訊息有較佳的能力或專業去蕪存菁，留下有用的資訊，使得他們在承擔大量的交易成本後，績效表現仍比中間群組為佳。

The thesis investigates trading and performance in common stock investment of individual investors of 52,649 accounts from January 1998 to September 2001. The average household earns a monthly return of —0.740%, tilts its common stock investment toward high-beta, growth stocks. The scale of the company is not the main factor when they select the stocks. We find that low turnover (quintile1) investors perform the best, the next are the high turnover (quintile5) investors. The high turnover investors may result from they hold more useful information and they are able to make a correct judgment. They even have better professional capability to make the best selection.
