The Shanghai and Shenzhen 300 Index appeared on April 8, 2005, in which the selection criteria of constituent stocks are scale and liquidity, with the latter accounting for a large proportion. According to these two indicators, the stocks in Shanghai and Shenzhen stock markets are sorted and then screened, which can reflect the changes of the most liquid and largest stocks in the market. In addition, new shares and stocks with abnormal conditions will not be selected, so the index can provide investors with more authoritative investment direction, and index funds with their constituent stocks as the target have always been welcomed by investors. The Shanghai and Shenzhen 300 Index has always been supported by A-share weathervanes.
Up to now, there are more than 20 CSI 300 index funds, including Shen Wanling's CSI 300 Value Index, Yinhe CSI 300 Value and Jing Shun Great Wall CSI 300 Enhancement. How to choose these index funds of the same type can refer to the following criteria: the strength of the fund company, the cost of the fund, the trend of the fund, and the fitting degree of the Shanghai and Shenzhen 300. No matter what type of fund a fund company chooses, its strength is the primary consideration. Even if the index fund is a passive fund, the investment mode and operation are relatively simple, but tracking the index is also a very complicated process, which requires rigorous calculation, so it is a strong company; The advantage of index funds is relatively low, but this low level is different. On this basis, the reduction is also very good, but the rate of return of the fund should also be considered; The degree of fitting with the index depends on whether the rise and fall of the index is positively related to the rate of return of the fund.
