Does the subject want to ask "Why does the fund need to increase by 2% when it falls by 1%"? A rise of 2% can achieve psychological expectations. When the fund loses money, it needs to increase more than the previous loss before it can be recovered. If a fund of 1 million yuan falls by 1%, it will be 9, yuan. At this time, if it rises by more than 1%, it will be 19,9 yuan plus 9,9 yuan. Therefore, a decline of 1% and an increase of 2% can achieve psychological expectations and achieve a state of no loss.
