A brokerage account is like a checking account for your investments: If your checking account is a clearinghouse for your income and expenses that acts as a safe place to store your cash, your brokerage account does the same for your investments.

An online best brokerage account empowers you to invest in the stock market. Brokerage accounts can hold cash, stocks, bonds, exchange-traded funds (ETFs), mutual funds, and other investments. Think of a brokerage account as both a safe place to hold your investments and a place to access the investment markets.
