"Relative income" refers to the income compared with the market, that is, when the market rises, we should strive to increase more than the market, and when the market falls, we should strive to decrease less than the market. For example, in a certain period of time, the market rises by 5% and the fund rises by 15%, then the relative return of the fund is10%; Of course, the return will not always be positive. Assuming that the market fell by 15% and the fund fell by 5%, although the return was negative, the fund still outperformed the market and gained the "relative return" of 10%, which can be said to be the investment goal.

Relative return is the difference between absolute return and some benchmark return. Used to describe the extra rewards people get by taking extra risks. This method is usually used to measure the return of mutual funds.
