The China Securities Index 500 (CSI 500) is an index jointly compiled by the China Securities Index Company and the Shanghai Stock Exchange. It selects the top 500 stocks from all A-share stocks in the Shanghai and Shenzhen stock markets after excluding the stocks in the CSI 300 Index, and reflects the overall performance of small and medium-sized companies in the two markets. The CSI 500 Index has high investment value.

The compilation method of the CSI 500 Index mainly uses stratified sampling and equal weight weighting. First, the China Securities Index Company stratifies all A-share stocks according to market capitalization, trading activity, and other factors, and selects sample stocks. Then, the sample stocks are weighted equally to calculate the index value, so as to avoid concentration of weight in a few stocks.

The investment value of the CSI 500 Index is mainly reflected in the following aspects: firstly, the CSI 500 Index covers the majority of small and medium-sized market capitalization companies in the Shanghai and Shenzhen stock markets, fully reflecting the overall situation of China's stock market; secondly, the sample stocks of the CSI 500 Index are stratified and weighted equally, with high representativeness and fairness; finally, the volatility and risk of the CSI 500 Index are relatively low, suitable for long-term investors.
