If you invest in junk bonds please know you are not investing in a garbage truck company or landfill operation. Junk bonds differ from other bonds simply because of their credit quality and high risk. But don’t let the term ‘junk’ fool you since they can pay high yields. If you want to get your analytical hat on and you have some motivation and extra cash, you may want to delve a bit into some junk bond investing. I would however, leave this kind of investing to the experts.
