A share broker is a professional who executes buy and sell orders for stocks and other securities on behalf of clients. Synonyms for this term include stockbroker, investment broker, securities broker, and trader. A stockbroker typically engages in the buying and selling of stocks, bonds, and other financial instruments and is licensed to give investment advice to clients. An investment broker, on the other hand, focuses on providing advice on different investment options such as mutual funds, exchange-traded funds (ETFs), and fixed income securities. A securities broker acts as an intermediary between buyers and sellers in the securities market, while a trader specializes in executing trades for their own account or on behalf of a firm.
