1. Look at the fund manager. The fund manager has a long management time and much experience in dealing with fluctuations. The historical performance of fund managers affects the performance of funds, and investors should try their best to choose fund managers with better historical performance.

2. Look at the standard deviation of the fund, which measures the fluctuation range of the total rate of return in a certain period. The greater the standard deviation, the greater the potential fluctuation of the fund's future net value and the higher the risk.

3. Look at the withdrawal rate of funds. The maximum withdrawal rate refers to the maximum loss rate that may occur at any time when buying funds. The higher the maximum withdrawal rate, the greater the loss. Therefore, investors should try their best to choose the consumer index fund with lower maximum withdrawal rate.

4. Looking at the scale of the fund, we need to pay attention to the scale when choosing the fund. For active management and consumption theme funds, it is best to choose a larger fund.
