Generally speaking, when the stock market is good, you can buy more stock funds, and when the stock market is weak, you can pay more attention to stable funds such as the bond market. There is only one purpose, that is, to obtain a higher return on investment than banks.
The internal operation of the fund is relatively simple, that is, to earn money from retail investors and rely on dividends. No matter what kind of market, money is transferred from one pocket to another. Making money means that you find value earlier than others.
