Buying a fund generally takes a long time to invest and will not be sold in a short time. After all, fund companies have professional teams.
Although the cost is higher than the stadium, you don't have to pay attention to the latest net value from time to time, and you don't have to pay too much attention to the temporary fluctuations (profit or loss) that affect your mood, unless you are gambling.
It is very convenient to buy and sell the funds in the market at the same time, and it is easy to make mistakes.
The above personal suggestions suggest that investment is risky.
