As the name implies, index funds are fund products with specific indexes (such as Shanghai and Shenzhen 300 Index, Standard & Poor's 500 Index, Nasdaq 100 Index, Nikkei 225 Index, etc.). ) as the target index, and take the constituent stocks of the index as the investment object, build a portfolio by buying all or part of the constituent stocks of the index, and track the performance of the target index. There are more and more index funds in the market, and it is more and more difficult to choose index funds. Investors should pay more attention to two points when choosing index funds: on the one hand, finding such an index is as difficult as choosing stocks; On the other hand, choose index funds with smaller investment tracking errors. The smaller the tracking error of funds, the stronger the management ability of fund managers, and the more investors can achieve the goal of obtaining index returns. Compared with actively managed funds, one of the advantages of index funds is low cost, but different index funds have different degrees of "low cost", so it is very necessary to minimize the investment cost. Of course, it should be noted that lower fees are important, but the premise is that the fund has good returns. Don't blindly choose index funds for lower fees.
The core of index fund lies in the index it tracks, so it is particularly important to know the corresponding market when choosing index fund. In addition, investors can also achieve the purpose of asset allocation by investing in different index funds. At present, there are many kinds of indexes in the domestic market, which can be described as "a hundred flowers blossom and a hundred schools of thought contend". Different indexes cover different markets and have different risk-return characteristics, such as Shanghai Stock Exchange 180 and Shenzhen Stock Exchange 100 index, which reflect the situation of Shanghai and Shenzhen stock markets respectively. CSI 100 and SME index reflect the situation of blue-chip enterprises and SMEs in Shanghai and Shenzhen stock markets respectively. Even with the launch of cross-border ETFs, it is a good asset allocation direction to choose the Shanghai and Shenzhen 300 index funds and funds investing in overseas market indexes at the same time, which can play a role in diversifying investment and risks to a certain extent.
