Short-term funds are actually playing with risks. This largely depends on personal operation and market conditions. If there is no market, even if the individual manages well, he will lose money. Some people hold the fund for more than seven days before selling it, and some people hold the fund for more than one year, which is very different. You can't say which way is the best, as long as you can make money, it is a good way. Personally, I generally hold the fund for about half a year. Of course, this is also the way to buy before. Now it will pay more attention to the market. This kind of fund situation like this year is more suitable for short-term. There will be a small peak in the short term, and then the fund will be sold. Generally speaking, it may be a small cycle of one or two months, so the time to hold the fund at this time is one or two months.
If the long-term situation is good, it can be held for a long time, one year or three years. Not only is this rate of return relatively stable, but the risk will be very low. So it depends on the individual. If you invest with spare money, you can put it for a longer time, but if you want to get higher returns in a short time, you need to do this according to market conditions. The number of days to keep can be one day or seven days. There is no clear standard for this.
