Index funds adopt the investment strategy of passively tracking an index. At present, there are Shanghai Stock Exchange Index, Shenzhen Stock Exchange Index, Shanghai Stock Exchange 180 Index, Shanghai Stock Exchange 50 Index and Shanghai-Shenzhen Stock Exchange 300 Index that can be tracked in China. Some index funds completely copy the index, buy all the constituent stocks according to the weight, and completely track the market, so that the market rose by 10%, and the fund also rose by 10%. Fund managers don't need to change shares frequently, so the level of fund managers has little impact on investment.

2. The risk is moderate

Ordinary investors have a poor stock selection, and the market has gone up, but every time the ticket goes up, they work hard, and the investment income is not as good as the increase of the market. At this time, choosing an index fund can guarantee the income in the same period as the market.

3. Middle income

Index funds that completely copy the index are especially suitable for those who have no time to study stocks but want to speculate. After a long time, they can get a good return by investing a fixed amount of money every month. This is an investment strategy of exchanging time for space.
