Similar to AMLP. Note of caution to anyone that starts investigating this. These are ETF's that own Energy MLP (Master LImited Partnerships). You may look at the MLP's these two ETF's own and think "why buy the ETF - the dividends of the underlying MLP's are much higher". You would be right in that but a word to the wise :
These MLP's get special tax treatment in order to pay these dividends. That means if you hold the individual MLP's you will get a K1 from each one that you will have to include on your taxes. If you buy these inside your tax deferred account (IRA, ROTH) you still have to pay these taxes - and it's an accounting hardship (people do it, but it's not straightforward).
Again, this isn't for the ETF's - AMLP and XMLP - they take care of the tax paperwork but they are charging you to do it - the dividends of what they hold are higher than what they pay you. I've owned AMLP in the past and it did a reverse split 1:5 so I dumped it as soon as I broke even on the principal - but I did receive the dividends the entire time.
One year return = 24.38%
If you invested $1 million in the average S&P 500 stock index fund, you'd be smoking fat cigars and doing $243,800 worth of hookers and coke.
