High Interest Investment

What are some BENEFITS of investing in a single investment grade bond?

I am looking for benefits or advantages of investing in one high rated bond, not disadvantages. If anyone knows of any documents stating any of these, I would REALLY appreciate it. Thank you! Also, how can investing in one bond be a better decision than diversifying a portfolio. This is a tough question, but I'm hoping someone might have some answers?? Please give sources, thanks!

1. The truth is you are better of diversifying. I would never hold a bond I would buy a mutual fund of bonds. At this time rates can only go up you want short duration bonds. I'm a fan of short duration bond funds right now.
