A stockbroker is a professional who buys and sells stocks and other securities on behalf of clients. They work for individuals, companies, or institutions, helping them invest in the financial markets. Stockbrokers provide advice on investment strategies and market trends, aiming to maximize returns for their clients. To become a stockbroker, individuals typically need a bachelor's degree in finance, economics, or a related field. They must also pass licensing exams, such as the Series 7 and Series 63, to legally trade securities. Stockbrokers earn money through commissions on trades and may also receive a salary.
