Hmm, let me see--market cap under $500M, daily trading volume averaging under 200K--I do believe you're correct,sir!
Today's volume was about 300K shares, or 50% higher than average, implying that one or more larger holders were lightening up, I think. Some people are calling the tops for energy MLPs, mostly pipes, but VNR may have been swept into the same dustbin by a few holders. Not a concern unless you're a trader--or the selling continues.
I was at the VNR presentation and breakout session at the IPAA conference. Both were well received. As a result of what I heard and the answers I received to my probing questions, I am increasing my stake in VNR.
