What you need to know about junk bonds.

Credit ratings are given to bonds so investors can gauge their stability. You're more likely to get your money back if you invest in bonds with higher ratings, since they're issued by financially secure companies. The highest rating is AAA. Bonds are given 'junk' or non-investment grade status if they have a rating of BB or less.

Some investors specialise in junk bonds since their riskier nature means they tend to offer higher yields. These individuals are willing to accept they may not get the money they invested back.
