In this session, we slog through the major types of bonds including Treasuries, mortgage-backed and asset-backed bonds (issued through a process called securitization), municipal bonds (a.k.a. munis), corporate secured and unsecured bonds (a.k.a. debentures), non-investment grade bonds (a.k.a. junk bonds, high-yield bonds, distressed bonds, speculative bonds), and foreign bonds. We finish with a discussion of bond ratings and the ratings agencies, bond quotes, and bond trading.
