A stock brokerage is a firm or individual that facilitates the buying and selling of stocks and other securities on behalf of clients. They act as intermediaries between investors and the stock market, providing access to various investment options. Stock brokerages can be traditional, offering personalized services, or online, allowing clients to trade independently through digital platforms. Investors typically pay a commission or fee for the services provided by a stock brokerage. These firms may also offer additional services, such as investment advice, research, and portfolio management, helping clients make informed decisions about their investments in the stock market.
