Fund conversion is a service provided by fund managers to fund holders. It refers to a business model that investors can freely switch to other open-end funds managed by a fund management company after holding any open-end fund issued by the fund management company, without redeeming the fund shares they have already held before purchasing the target fund. When the trading account is normal and the fund applying for conversion must be a convertible fund designated by the fund management company, the conversion transaction can be carried out.

Closed-end funds and open-end funds cannot be converted to each other, and closed-end funds should be listed and traded on the exchange. At present, only open-end funds can be converted.
