One to consider for your IRA: AMZAAMZA is a ETF that mainly invests in the energy (mainly oil) industry for high dividends. I see the current drop as an opportunity for dividend investors. Limited partnerships can be tricky at tax time outside a IRA so I only put them there myself. Dropping 3% today. Watch for signs of it bottoming from price action. At a price of 8 it gives a >16% dividend.
"The investment seeks total return primarily through investments in equity securities of publicly traded master limited partnerships and limited liability companies taxed as partnerships ("MLPs"). Under normal market conditions, the fund will invest not less than 80% of its assets in equity securities of MLPs in the energy infrastructure sector. It is non-diversified."
