英文摘要：

Investor sentiment is the outward manifestation of irrational expectation, and its premise and the foundation is the inves- tor expectation. Our analysis is based on the relationship between expectation and sentiment. From four aspects： macro-economic expectation, stock market performance and expectation, influence of the media, investors＇ earnings forecasts, we select five indica- tors： macro-economic prosperity index, return of SSE composite index, trading volume, quantity of news, investors＇ earnings fore- casts. By path analysis, we analyze the relations between those five indictors and the following four proxy variables： consumer con- fidence index, number of new accounts, turnover and price/earnings ratio of stock market, and construct a model to analyze their re- lations.
