I found this an interesting article: Thoughts for Today's Bond Market
The author concludes:
In my portfolio, I hold cash rather than bonds. I don't wish to lock into yields at today's low rates. If I were in bonds, though, the presentation suggests that I: own intermediate-term issues rather than long bonds; favor high-quality corporates over Treasuries; and consider other assets, stocks included, as a hedge against further rate increases.
The article includes a corporate credit spread chart.
