As you know, the difference between the two is that the amount of investment subscribed is generally more than the fixed investment. Although it is more flexible than fixed investment, it can be bought and sold almost every trading day. Fixed investment can only be bought on a weekly or monthly basis, and the redemption time is arbitrary. Funds are different from stocks. You buy and sell net worth at the close of the day. You can't say that your selling price is different at different times of the day.
