Forecast the future trend of the fund according to the net worth chart. When the fund unit net worth chart is in the downward channel, its net worth may continue to fall, and vice versa.

There are three curves in the trend of fund cumulative return rate, which represent fund return rate, Shanghai Composite Index return rate and Shanghai and Shenzhen 300 Index return rate respectively. If the overall trend of the fund's return rate far exceeds that of the Shanghai Composite Index and the Shanghai and Shenzhen 300, it shows that the fund's current return is good and gradually increasing; If it is lower than the Shanghai Composite Index and the Shanghai and Shenzhen 300 Index, it means that it has underperformed the broader market, and such a fund may not have obvious advantages in income.
