Refers to the fixed investment of CCB. Fixed investment is the abbreviation of fixed investment fund, which means to invest in a designated open-end fund at a fixed time (for example, the 8th of each month) with a fixed amount (for example, 300 yuan), similar to the deposit and withdrawal method of banks. This kind of investment can average the cost and spread the risk, which is more suitable for long-term investment. The investment fund share can be redeemed in part or in whole at any time, and the redemption amount is equal to the redemption fund share * the latest net value on the redemption date-redemption fee. It can be cashed within 7 days. It is best to redeem the fund after it has earned a return on income.
