Bond funds are investment vehicles that pool money from multiple investors to purchase a variety of bonds. These funds typically invest in government, municipal, or corporate bonds, providing investors with a diversified portfolio. By investing in bond funds, individuals can gain exposure to fixed-income securities without having to buy individual bonds themselves. Investing in bond funds can offer regular income through interest payments, which are distributed to investors. They are generally considered less risky than stock funds, making them a popular choice for conservative investors seeking stability and income in their investment strategy.
