If the profit is calculated by time, it is the money recovered from the investment MINUS the money invested, and the balance is greater than zero, which is the profit of this investment.
If the profit is calculated by cycle, for example, one year.
The amount of funds invested at the beginning of the year should be recorded.
Calculate the year-end fund balance, plus the market value of wealth management products. These two sums are subtracted from the amount of funds invested at the beginning of the year, and the positive balance is the profit.
