A "펀드 매니저" (fund manager) is a professional responsible for making investment decisions on behalf of a mutual fund or investment fund. Their main goal is to grow the fund's assets by selecting the right mix of stocks, bonds, and other financial instruments. They analyze market trends, economic data, and company performance to make informed choices. Fund managers often work for investment firms or hedge funds and may specialize in specific sectors or asset classes. They are accountable for the fund's performance and must communicate results to investors, ensuring transparency and trust in their investment strategies.
