As Charlie has stated before, the first half of 2009 was a golden age during which to build a high yield corporate bond portfolio. Investment grade bonds were yielding much higher than normal and junk bonds were selling at extraordinary discounts that made the added risk in investing in them worthwhile.Unfortunately, I only purchased one batch of Prudential bonds during that golden moment. It yielded 10% and was rated in low A's -- investment grade. Since then, I've been chasing yield albeit while accepting greater risk. My bond portfolio is, therefore, largely based on junk bonds. (The batch of Prudential I purchased was called early!)To try to up the average quality of my bond portfolio, I set the Etrade search engine to the low end of investment grade. The highest yielder is Tenneco Packaging Incorporated. They have three sets of bonds yielding 9% plus. They are rated Baaa2/BBB, but these rating date back to 2002! The parent company of Tenneco is Pactiv (PTV) which itself is being bought out by Reynolds Group Holdings. (The makers of Reynolds Wrap.)My inclination is to think packaging is a pretty secure industry regardless of the state of the economy. Anyone have an opinion on Tenneco's bonds?
