interest rate bond funds can be bought during trading hours.
Theoretically speaking, we can buy bond funds when the market interest rate is high, and we can choose long-term bonds for more than one year. When the market interest rate is low, it is recommended to buy short-term bonds, because once you encounter a bond floating loss, you can make a fixed investment when it falls.
I would like to ask, is the 8 yuan investment and financial management software reliable?
