portfolio manager financial

""other": "PORTFOLIO MANAGER""

A portfolio manager is the professional who picks and oversees a collection of investments—such as stocks, bonds, and cash—on behalf of individuals or institutions. They make decisions about which assets to buy, hold or sell and how much risk to take, like a ship captain steering through changing weather; their choices shape an investor’s potential returns, losses and the steadiness of the investment experience.
