It's not what you think ... whether it's a big company fund or a small company fund, its general trend is actually similar to that of the broader market. The market has gone up and down. The significance of fixed investment is to sell the fund when the market rises. If you consciously continue for five years, you will definitely not lose money, because there is almost no chance that the market will plummet for five years in a row, but you should be prepared for this. If it is released for three years, the fund has risen a lot and can be sold. It's not necessary.
