Abstract: | 本論文希望建立一個綜合性的投資者關注度指數,以探討其對台灣50指數報酬率的影響。透過主成分分析 (PCA) 和偏最小平方法 (PLS),我們將7個單獨的投資人關注度代理變數整合為綜合指數,以預測報酬率。實證結果顯示,採用PLS方法建構的投資者關注度綜合指數,在3、6及12個月的時間範圍內,無論是否調整極端值,對台灣50指數報酬率均展現出強大的預測能力,尤其在調整極端值後,其效果更為突出;而採用PCA方法建構的投資者關注度綜合指數則未顯示出顯著的預測能力。在單獨的代理變數中,異常交易量以及過去報酬率與台灣50指數報酬率之間呈現出顯著相關性。 This study examines how aggregate investor attention indexes affect returns for the Taiwan 50 Index. Using Principal Component Analysis (PCA) and Partial Least Squares (PLS) methods, the research builds comprehensive aggregate investor attention indexes based on seven well-known individual proxies. The empirical results showed that the aggregate investor attention index constructed by the PLS method had strong predictive power over 3, 6, and 12-month periods, regardless of whether extreme values were adjusted, and notably strengthened after such adjustments. In contrast, the aggregate investor attention index constructed by the PCA method generally lacks significant predictive ability. Among the individual attention proxies, abnormal trading volume and past return demonstrated significant correlations with Taiwan 50 Index returns. |
