This factor reflects the change in the market's consensus expectations for the company's earnings outlook by calculating the relative proportion of the difference in the number of analysts' upward and downward revisions to earnings per share (EPS) forecasts. A positive value indicates that the market's expectations for the company's profitability have tended to be optimistic in the past three months, while a negative value indicates that expectations have tended to be pessimistic. This factor can capture changes in analyst sentiment and serve as a potential signal for predicting future stock returns. Specifically, when analysts generally raise EPS expectations, it may indicate that the company's future profitability will increase, and thus the stock price has the potential to rise; conversely, when analysts generally lower EPS expectations, it may indicate that the company's future profitability will weaken, and thus the stock price has the risk of falling. This factor belongs to the analyst sentiment factor and also has the characteristics of the earnings expectation factor. It should be noted that this factor is not an absolute investment signal and needs to be combined with other factors and fundamental information for comprehensive analysis.
