Moody's Baa Corporate Bond Index reflects the average yield of constituent corporate bonds that have been given Moody's Baa credit rating. Corporate bonds can receive ratings that range from a high of Aaa to a low of C. Bonds given the Baa rating are considered as medium-grade obligations, meaning they are neither highly protected nor poorly secured. Bonds rated Baa and above are considered investment grade.
