Stocks can be used as assets and are a way to prove assets when applying for a credit card.

However, you cannot use a credit card directly to buy stocks. You can only use a credit card to withdraw cash (there is a handling fee), deposit it into a bank account bound to a securities account, and then transfer the funds to the stock market to buy stocks.

The general method of investing with a credit card is to swipe the credit card to wholesale goods, and then use the payment for the goods to repay the money. Generally, more than 3 credit cards are used for recurring repayments.
