No, although there is a saying in the fund market that you don't buy on Thursday and don't sell on Friday, it is not aimed at the money fund. Money funds can be bought on Thursday or sold on Friday, because: if you buy money funds on Thursday, you will confirm your share on Friday, and you will get profits on Friday and weekend, so you can buy them on Thursday. In addition, it can also be sold on Friday, because no matter around three o'clock on Friday, there will be gains from selling. For example, it will be sold before three o'clock on Friday, and the share will be confirmed next Monday, so there will be gains on the weekend.
Therefore, the money fund does not have this statement, but other funds have this statement because it will usher in the weekend after buying on Thursday. After buying it on Thursday, there was bad news on the weekend, and it fell on Monday. If you don't sell it on Friday, you are afraid of bad news. If it is sold on Friday, the funds will not arrive soon, and it will take 2-3 trading days to arrive. However, in case of a sharp rise on Friday, equity funds can be sold appropriately.
