Securities Markets

Bonds vary in quality, depending on the financial strength of the issuer. Because the claims of bondholders come before those of stockholders, bonds are generally considered less risky than stocks. However, some bonds are in fact quite risky. Companies can default – fail to make scheduled interest or principal payments – on their bonds. Investors can use bond ratings, letter grades assigned to bond issues to indicate their quality or level of risk. Ratings for corporate bonds are easy to find. The two largest and best-known rating agencies are Moody's and Standard & Poor's (S&P), whose publications are in most libraries and in stock brokerages. Figure lists the letter grades assigned by Moody's and S&P. A bond's rating may change if a company's financial condition changes.
