The so-called fund rate of return is the probability of profit in the process of fund operation, that is, the cycle ratio of positive return (or exceeding the benchmark) of the fund. The commonly used statistical interval is Zhou Du and monthly, so it is sometimes called Zhou Du winning rate and monthly winning rate.

The calculation method is: the monthly winning rate of the fund = the number of months with positive income at the end of each month/the total number of months. The higher the success rate of the fund, the better. It is a good reference index when buying funds. Generally, the monthly winning rate should be above 50%.
