I don't have all the historical figures, but FGP has bounced around between $18 and $25 for more than a decade.
When I bought in about two years back I averaged in at about 18 and figured that $22-23 would be "fully valued". I still see that as a good valuation...
...however, with the interest rate environment still at historic lows, the distribution that FGP pays (and hopefully continues to pay) _may_ support the higher than historic trading range. If I were a recent purchaser of FGP units, I would just sit tight and believe that the selling pressure should end in the next couple of says and the unit price will drift slowly back up to at least the 28's.
And, didn't the CEO even comment about potentially raising the distribution?
