Answer:
"Commercial paper, or unsecured promissory notes, can be a lucrative, yet often risky venture. Although often only issued by large and mainly stable corporations, for the beginner or unknowledgable investor, often the risks may outweigh the possible benefits. The main risks include lack of turn-around time on investment capital, tying up funds that may otherwise be needed elsewhere, mismanagement by the issuing corporation causing bankruptcy, and a general lack of interest rates, making them less of an investment opportunity when it comes to rapid portfolio growth."
