A portfolio manager is a financial professional responsible for managing investment portfolios on behalf of clients, which can include individuals, institutions, or mutual funds. Their main goal is to maximize returns while minimizing risks by selecting a mix of assets, such as stocks, bonds, and other securities. They analyze market trends and economic data to make informed investment decisions. Portfolio managers often work as part of a team and may collaborate with analysts and traders. They regularly review and adjust the portfolio to align with clients' financial goals and risk tolerance. Effective communication with clients is also essential to explain strategies and performance.
