    Abstract:

    This paper studies investor sentiment with three different frequencies: daily,weekly and monthly, and applies MIDAS model to study the effects of mixed-frequency investor sentiment on stock market return and volatility. It is found that the mixed-frequency sentiment has a significant positive impact on both return and volatility and that the MIDAS model outperforms the traditional regression model. The GARCH-MIDAS model is used to study the effect of mixed-frequency sentiment on the stock volatility,and it is found that the mixed-frequency sentiment significantly affects the long-term volatility.
