Bonds are a type of fixed-income security that is issued by companies, municipalities, and governments to raise capital. Essentially, a bond is a loan that an investor gives to the issuer in exchange for regular interest payments and the return of their principal investment at a specified date in the future. There are several types of bonds including corporate bonds, municipal bonds, treasury bonds, and high-yield bonds. While bonds provide benefits like a regular income stream and lower risk than stocks, they also carry risks such as interest rate risk, credit risk, and inflation risk. Investors can purchase individual bonds or invest in bond funds to build a diversified portfolio.
