摘要: 
本研究以台灣上市櫃公司為樣本,探討焦點效應如何影響長期股價報酬。本研究提出的假說為焦點效應使公司被錯誤訂價,直到長期股價進行修正,將反轉回歸基本面。研究方法中,我們編製焦點效應指數,提供一個衡量焦點效應強弱的量化指標。在實證結果,首先,我們發現焦點效應對長期股價報酬有顯著的負向影響,且高焦點效應的投組,將有負的股價報酬。在金融海嘯期間,由於投資人追求高品質證券的行為,將加劇焦點效應對股價報酬的影響力。再者,我們發現小規模、低淨值市價比、年輕、高個別風險之公司,焦點效應對股價報酬的影響力將會增加。最後,我們藉由焦點效應形成投資策略,發現能獲得良好的報酬。本研究的實證結果與假說一致,支持由焦點效應驅策的股價,將經歷從錯價到修正的過程。

This paper studies how attention effect affects long-term stock return in Taiwan's listed stock market. This paper hypothesizes that stock price will correct and reverse to fundamentals as a result of short-term attention-driven mispricing. In my methodology, we calculate attention effect indices to provide a quantitative indicator of the strength of attention effect. In empirical results, firstly, we find that attention effect index has significant negative impact on long-term stock return and the portfolio of high-index has negative mean return. we also find that long-term stock return is more sensitive to atten-tion effect during the financial crisis of 2007-2009 due to the behavior of investors' flight-to-quality. Furthermore, long-term stock return of certain firms—small size, low B/M, young, high idiosyncratic risk—is also more sensitive to attention effect. Finally, we use some attention-based investment strategies and find that we can get good long-term stock return. Consistent with hypotheses, empirical results support that atten-tion-driven stock price will experience the process of mispricing to correction.
