Within a buy-side firm, the portfolio manager is responsible for executing the portfolio strategy. They
oversee investment decisions, asset allocation, and security selection based on the investment
mandate and client objectives. Other roles:
Head of fixed income (B) specializes in fixed-income securities rather than overall strategy.
Investment advisor (C) interacts with clients, focusing on advice rather than execution.
Trader (D) carries out transactions but does not set the portfolio strategy.
