根據台灣證券交易所(TWSE)證券統計資料年報顯示，2010年台灣股票市場中散戶投資人交易成交值比重約為68%，外國機構投資人約為18.5%。一般而言，外國機構投資人被視為具有專業分析能力的交易者，散戶投資人則為雜訊交易者。在本文中我們將藉由觀察各類型投資人的交易行為，探討台灣股票市場中不具有資訊內涵的散戶投資人是否會跟隨具有資訊的外國機構投資人的交易行為。
為了瞭解散戶投資人是否有跟隨外國機構投資人的情況，我們在本文中分別使用事件研究法與向量自我迴歸模型(VAR)模型加以分析各類型投資人的交易行為。我們發現，外國機構投資人為正向回饋的動能交易者，本國機構投資人及散戶投資人為反向操作者；然而當發生金融風暴時，外國機構投資人轉變為反向操作者，散戶投資人轉為正向回饋的動能交易者。透過向量迴歸模型，我們發現散戶投資人的交易行為並不會受到前期外國機構投資人交易行為的影響，顯示散戶投資人並未跟隨外國機構投資人的交易行為。 / According to Taiwan Stock Exchange Corporation (TWSE), individual investors accounted for 68% trading volume and foreign institutional investors accounted for 18.5% in stock market in 2010. In general, we regard foreign institutional investors as traders with professional analysis abilities. However, we thought individual investors are noise trader. We would like to know whether the individual investors follow foreign institutional investors’ transactions and elaborate their transaction behavior.
In order to understand whether individual investors follow the foreign institutional investors, we used event study and VAR to analyze their transaction behavior. We observed that foreign institutional investors are momentum traders. On contrary, we noticed that domestic institute investors and individuals are contrarian traders. Nevertheless, during financial crisis, foreign institutional investors became contrarian traders and individual turned to momentum traders. Through VAR model, we found that individual did not follow foreign institutional investors.
