Please help me solve Behavioral Finance exercise:

a We can observe a very optimistic sentiment when the market gets a signal consistent with a bear market and quite modestly pessimistic sentiment when the signal is consistent with a bull market. Using the setup of Chapter 15 in the book, with two types of investors in the market - what would lead to such a market sentiment function? If you were to generate such a sentiment function, what would the two types of investors be described, and what proportion would the investors present in the market? Please provide a figure of such a sentiment function and explain how such a sentiment in the market can / should affect asset prices. a We can observe a very optimistic sentiment when the market gets a signal consistent with a bear market and quite modestly pessimistic sentiment when the signal is consistent with a bull market.
