Baker and Wurgler  take a “top down” approach to behavioral finance and the stock market. Investor sentiment is taken to be exogenous and the focus is on its empirical effects. Sentiment is measurable and its waves have clearly discernible, important, and regular effects on firms and the overall stock market. Stocks that are hardest to arbitrage or value are most affected by sentiment.
Other studies discussed relate to aspects of investor sentiment and sentiment indexes in Baker and Wurgler  and/or Baker and Wurgler . Massa and Yadav  analyze whether mutual funds opportunistically exploit market inability to identify sentiment risk. Gasbarro et al.  determine that when fund investor sentiment is high (low), returns are higher for funds with low (high) sentiment-beta portfolios. Irek and Lehnert  use the sentiment index and find that market risk is not a priced factor of expected fund returns when investor sentiment is positive. Sibley et al.  determine that although sentiment is orthogonal to macroeconomic conditions, sentiment indexes have substantial information related to business cycles. Joseph et al.  find that intensity of searches for ticker symbols serves as a valid proxy for investor sentiment, which is useful for forecasting stock returns and trade volume. Huang et al.  determine that the sentiment index likely understates the predictive power of investor sentiment.
