It should be noted that etf funds are traded in real time. If investors want to trade in real time, it is best to choose etf funds. If investors have no requirements for real-time trading, they can choose ordinary funds, which are usually bought on the same day and confirmed on the second trading day.
Etf funds invest in a specific index and buy some or all of the shares of the index in order to obtain the same income as the index. General funds include money funds, bond funds, hybrid funds, stock funds, LOF funds and so on.
