Obviously you are just looking at the chart for recent moves. Try looking at the Yahoo comparison chart. Since mid 2001 the unit stock price of NRGY has risen approximately 200% more than SPH. I hardly call that terrible, unless you are an in and out "day trader". SPH does have a nicer dividend at the moment, and I may get some to add to my portfolio. Again, NRGY unit share price has outperformed SPH.
