效率市場一直是傳統財務理論的核心，然而現實的投資環境中卻一再發現傳統財務學無法解釋的不效率現象，例如小公司效應（small firm effect）、本益比效應（price/earnings effect）、面值市值比效應（book value/market value effect）、元月效應（January effect）、週末效應（weekend effect）等。行為財務學認為投資人的行為偏誤是造成市場不效率的原因之一，而這些偏誤是會一再重複而有機可循的，因此發展出動能策略（momentum strategy）、反向策略（contrarian strategy）等，藉由研究投資人的行為對股票市場進行預測並投資。
台灣市場一直是散戶居多，而且又是屬於淺碟型的小市場，理論上投資人的行為偏誤將會更加顯著，也意味著行為財務學將有更多的發展空間，雖然行為財務學的理論已經被廣泛的實證研究，但是因為投資人的行為往往會因為不同地域、不同情境、不同時空等因素而有所差別，鑒於目前台灣市場尚未有相關的投資方式，因此希望藉由本研究促進國內產學界更深入探討行為財務學在投資方面的應用，進而促使台灣投資市場的更加效率。 / Efficient market has been the core of traditional financial theory. However, in real world, unexplainable phenomenon of inefficiency has been discovered, e.g., small firm effect, price/earnings effect, book value/market value effect, January effect, weekend effect, etc. According to behavioral finance, investors’ behavior biases are one of the main causes, and these biases will repeat themselves. Therefore, momentum strategy and contrarian strategy are performed in investment to try to forecast the market.
Taiwan stock market is small and has been full of undisciplined individual investors. Theoretically, investors’ behavior biases are more easily to find, which means behavioral finance should apply better in Taiwan. Although the theory of behavioral finance has been widely testified, the outcomes are always different from areas, scenarios, times etc. Considered that, behavioral finance has not been applied in Taiwan stock market. This study focuses on application of behavioral finance in Taiwan. Hope that through this study to promote domestic industry and academy to deeply explore the application of behavioral finance in investment, thereby promoting more efficiency of the investment market in Taiwan.
