No, credit cards are only used for consumption and cannot be used for other purposes (including investing in wealth management fund stocks). Moreover, credit card is a credit line, which can only be used for credit card or third-party payment, and cannot be transferred or withdrawn, and cannot be directly used to buy funds.

Investors can only buy funds with their own funds. If they use credit loans to buy funds or other funds that cannot be used for investment, the system will freeze the funds after testing.
