A brokerage firm, or simply brokerage, is a financial institution that facilitates the buying and selling of financial securities between a buyer and a seller. Brokerage firms serve a clientele of investors who trade public stocks and other securities, usually through the firm's agent stockbrokers. A traditional, or "full service," brokerage firm usually undertakes more than simply carrying out a stock or bond trade. The staff of this type of brokerage firm is entrusted with the responsibility of researching the markets to provide appropriate recommendations, and in doing so they direct the actions of pension fund managers and portfolio managers alike. These firms also offer margin loans for certain approved clients to purchase investments on credit, subject to agreed terms and conditions. Traditional brokerage firms have also become a source of up-to-date stock prices and quotes.
