I have been on a number of conferance calls and there were states made that connected earnings with conservation do to propane price increases.
both NRGY and FGP both missed and stated that the higher propane prices had effected earnings. not that pipe is not another reason. a clear picture of what i'm saying can be seen be viewed at yahoo uso and ^amz chart
other factors, hegde funds and credit play into what looks like the perfect storm, and why this sector is going south.
