It’s okay not to buy it.

If you only buy one fund, it must be a broad index fund.

What is a broad index? Generally speaking, a broad index refers to an index fund that has a wide coverage of constituent stocks and is quite representative. It generally covers a wide range of industries, such as the well-known Shanghai Composite Index, CSI 300 Index, and CSI

500 Index, GEM Index, etc.

Individual stocks are underweighted and the investment objectives are broader.

A broad base is a fund that invests in a broad index.

The benefits of choosing a broad base, Buffett said: For many investors, the best thing you can do is to hold S&P 500 funds.

The S&P 500 here is actually a broad index in the United States, equivalent to my country's CSI 300 and CSI 500.

The CSI 300 Index represents the stock index of the 300 best companies in the entire market.

It can also be said that the CSI 300 Index Fund earns the average return from investing in these 300 companies.

In fact, it is equivalent to the average return of the entire market.
