I like the fund AMJ which has a good group of oil and gas stocks and has a yield of 5%. Also, the fund is the pick of the year on the following site. If you look at the past performance of AMJ, it had a pull back with the gulf oil spill, but it is now moving higher. I like the dividend yield over PBR. And AMJ should move higher if PBR does turn around.
I am a big fan of the mid-stream NG MLP... so go with KMP, MMP, PAA, ETP, etc.
These companies have high yields (above your 5%), are required to distribute profits to the partners (which they do with no taxation at the corporate level, i.e. tax-advantaged), operate as quasi-monopolies (how many pipelines do you have running from any point A to any point B?), with long term contracts, in a growing industry (NG is a growth industry in the USA and world-wide) and without the pricing, cost and operational risks of E & P.
If you are an income investor, what is not to like?
