The first is exchange-traded ETF index funds. You can directly enter the fund code and buy and sell it like buying stocks. For example, if you search for the initial letters of brokerage ETFs, the brokerage ETF code of Huabao Fund Company will appear: 512000, etc. Just like stock trading, just click to buy. The buying fee is generally the same as the stock trading fee.

The second is to purchase broker-linked funds and follow the principle of share subscription and redemption. If you search for "brokerage" on Tiantian Fund Network or Alipay and other fund sales institutions, there will be Huabao Securities ETF feeder funds appearing.

Notes on buying ETF funds

First, look at the premium rate, that is, market price/net value. If there is leverage, such as GEM B\SME Board B, the premium rate can be 15% about. Without leverage, the premium rate should generally not exceed 5%. If it is too large, it means that the tracking error of the fund company is too large or there are other reasons. In short, it is abnormal.

Second, it depends on the on-site and off-site shares. There are both on-site and off-site shares, and they are convertible to each other. Because there are arbitrage opportunities, the deviation between the price and the net value will generally not be too large.
