Investment funds are pools of money collected from multiple investors to purchase a diversified portfolio of assets, such as stocks, bonds, or real estate. These funds are managed by professional fund managers who make investment decisions on behalf of the investors, aiming to achieve specific financial goals. There are various types of investment funds, including mutual funds, exchange-traded funds (ETFs), and hedge funds. Each type has its own investment strategy, risk level, and fee structure, allowing investors to choose funds that align with their financial objectives and risk tolerance.
