For example, if you buy a fund of 1 1,000 yuan, you lose 1 1,000 yuan, leaving the net value of 900 yuan, and then you can only convert the equivalent value of 900 yuan into other funds. Losses can still be converted, but the net value of the fund is reduced, and the convertible fund share is reduced, which is not cost-effective. If it is a change in investment style, it can be converted according to personal needs.
