    This study examines how investor sentiment influences stock returns. This study employs principal component analysis to form a composite index of sentiment. The sentiment proxies include the market turnover, the number of initial public offerings, the returns of initial public offerings, the equity share in new issues, the ratio of the number of advancing issues to declining issues, the ARMS index, the ratio of the number of new highs to new lows, the percent change in margin borrowing, the percent change in short interest, and the ratio of short sales to total sales. Furthermore, the investor sentiment variable is included in the panel data regression model to examine whether investor sentiment can explain stock returns in Taiwan. The empirical results show that the portfolio returns of high investor sentiment are higher than low investor sentiment. Moreover, the effect of firm characteristics on stock returns is diverse under different investor sentiments. Finally, the current sentiment indexes have positive influence on stock returns at the current period while the lagged sentiment indexes have negative impacts on stock returns at the current period.
