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.
The stronger the issuer's financial position the higher the credit rating assigned to the company. The top rating is 10 which is for AAA ratings -- the gold standrd. These securities set the benchmark for safety and all other bonds are rated relative to the safety of owning them. The ratings table is divided into two primary categories. Investment grade and speculative grade ratings.
