Investment-grade corporate bonds are debt securities issued by corporations that have a high credit rating. They are considered to be a relatively safe investment, as the issuers are typically large, well-established companies with a strong track record of financial performance. As a result, investment-grade corporate bonds typically offer lower interest rates than other types of bonds, such as high-yield bonds.
There are a number of reasons why investors might want to buy investment-grade corporate bonds. First, they can provide a steady stream of income. Second, they can help to diversify an investment portfolio. Third, they can be used to hedge against inflation. Finally, they can be a good way to save for retirement.
