The difference between colored 800a and B lies in the different income. Generally, the income of class A funds is higher than that of class B funds. The full names of colored 800a and B are "Xincheng CSI 800 colored index grading A" and "Xincheng CSI 800 colored index grading B". These are the two shares of the same stock fund CSI 800, and the difference lies in the rate of return after buying the fund.

Class A fund is the only fund in all fund wealth management products that can be publicized with "agreed rate of return". Even money funds can only use the annualized rate of return for nearly seven days, and cannot use the "expected rate of return" and "agreed rate of return" for publicity. Agreed income funds with a time limit are often loved by investors with low risk tolerance, unable to reach the threshold of 50,000 yuan for bank financing and needing high returns.
