By David Ashworth | Mar 12, 2015 10:09 am EDT. Investment-grade bonds are fixed-income issuances with a rating of BBB and above as provided by credit ratings agency S&P (Standard & Poorâs). The agency uses modifiers + and â to show relative standing within the major rating categories.
With bonds, prices are determined based on how ratings companies, like S&P and Fitch, rate the creditworthiness of the issuer of the bond. For example, a corporate bond issued by Apple is rated AAA, which means the ratings agency has very high confidence in the ability of Apple to repay its loan, the bond debt that the bondholders own.
