The fund is scheduled to expire in three years and the contract will be automatically terminated. If you want to continue the fixed investment, you can only re-sign the fixed investment agreement. You can choose to redeem the original fund or continue to hold it. When and how much to redeem is up to you. In case of partial redemption, the share bought first will be redeemed first. (Different holding time may lead to different redemption rates). If you continue to hold it, the market value of the original fund will change with the fluctuation of the stock market. When you redeem it, settle it according to the net value at that time.
After that, continue to apply for fixed investment. As long as it is the same fund, the reprocessed share will be accumulated into your account together with the original share of the first phase. The only difference is that the holding time is different and the handling fee rate is different when redeeming.
