What title is given to a person who buys and sells securities for a brokerage firm's account?

The role of a trader is specifically designed for individuals who buy and sell securities, such as stocks and bonds, on behalf of a brokerage firm. Traders execute trades to take advantage of market conditions, manage the firm's investment portfolio, or facilitate the buying and selling of securities for clients. This role requires a deep understanding of market trends, pricing, and trading strategies.

In contrast, investment bankers focus on raising capital for companies, managing mergers and acquisitions, and providing advisory services, which distinguishes their responsibilities from those of a trader. Research analysts work on analyzing market conditions and specific securities to provide insights, but they do not actively execute trades. Investment adviser representatives typically provide personalized investment advice to clients rather than engaging directly in trading activities.

Therefore, the correct title for a person involved in the buying and selling of securities for a brokerage firm's account is indeed a trader.
