Since my team helped re-launch the JPMorgan Alerian MLP Index ETN (AMJ) in 2009 (which was first launched as a Bear Stearns ETN in 2007), I have found it to be a convenient, IRA-friendly benchmark for the high yielding sector of master limited partnerships (MLPs) that largely provide access to multi-state pipeline infrastructure. Since then, the Alerian MLP ETF (AMLP) launched in 2010. It has a significantly different tax structure and somewhat different portfolio weights, but can otherwise be thought of as another IRA-friendly MLP benchmark.
