Buy funds on weekends and sundays, according to the net value of next Monday. Under normal circumstances, funds purchased before 15: 00 are calculated according to the net value of the current day, and funds purchased after 15: 00 are calculated according to the net value of the next day. It is recommended not to buy funds on Saturday and Sunday, and then decide after the market opens next Monday to see the ups and downs of the day. If the increase is too large, there is no need to buy it. Now the stock market is unstable and there are many opportunities.
