Looks like they chose today to do this unwind around options expiration. MLPS plunged down nearly 5 points on the mlp index with a lot of 1 point losses but with the market they've turned those around and the index is down less than 2 now. Buckeye Partners (BPL) El Paso (EPB) Targa (NLGS) and Vanguard Resource (VNR) remain down 1 or more. But others like Atlas Pipeline (APL) Markwest (MWE) EV Partners (EVEP) and Oneok (OKS) among others have come well off their lows.

Inergy LP (NRGY) is up nearly half a buck and leads a short but lengthening list of winners today. Last hour looks firm.
