The premise is: long-term fixed investment, 10 years or more. The CSI 500 Index is a small-cap stock index, which is a stock with strong growth but large fluctuations in the short and medium term. Under the long-term fixed investment, such stocks have the largest increase, which is suitable for the long-term fixed investment of the Fund. CSI 300 is a blue-chip company, which is a mature and stable large company in all walks of life. The fluctuation range is not as good as that of small companies. Predictably, under the long-term fixed investment, the growth of this index fund is not as good as that of CSI 500.

Of course, it is understandable to recognize and like mature large companies represented by the Shanghai and Shenzhen 300 Index.
