1, convenient and flexible investment: investors can buy or redeem open-end funds from fund management companies at any time, while closed-end funds may not be able to buy or sell because of poor liquidity because transactions are only between investors.

2. Reasonable transaction price: The subscription and redemption prices of open-end funds are determined according to the net asset value of the fund unit plus or minus a certain handling fee on the day of application, and there is no discount transaction, which is beneficial to investors.

3. Risk control is more effective: the main income of fund managers is to withdraw fund management fees according to the fund's net assets, while investors can buy and redeem open-end funds at any time, and fund management companies are facing greater redemption pressure, thus prompting fund management companies to manage open-end funds more cautiously, pay attention to risk management such as liquidity, and strive to achieve a win-win situation for investors and fund management companies.

4. High information transparency: According to the current relevant laws and regulations, fund managers of open-end funds should announce the net asset value of open-end fund shares on the second day of each open day, so that investors can make correct decisions accordingly. It can be seen that open-end funds are more conducive to protecting the interests of investors. In order to effectively protect the interests of investors, fund companies are currently issuing open-end funds. In the future, existing closed-end funds may also be converted into open-end funds.
