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 live stock prices and quotes. When a brokerage firm, in addition to buying and selling for clients, transacts for its own account, it is known as a broker-dealer.

Many broker-dealers also serve primarily as distributors for mutual fund shares. These broker-dealers may be compensated in numerous ways and, like all broker-dealers in the United States, are subject to compliance with requirements of the US Securities and Exchange Commission and one or more self-regulatory organizations, such as the Financial Industry Regulatory Authority (FINRA). In the meantime, distributors to be paid upfront fees and trail fees, which is now one form of distributor’s earnings. The forms of compensation may be sales loads from investors, or Rule 12b-1 fees or servicing fees paid by the mutual funds.
