Another GP bites the dust as Penn Virginia Resource (PVR) buys Penn Virginia Group Holdings (PVG). This leaves Nustar Holdings (NSH) Atlas Holdings (AHD) and Crosstex (XTXI) among the few remaining gps out there. Nustar Holdings (NSH) is up to 33 and is higher today. Judging from the market action latetly in these GPs, there is premium already built into prices as they seem to be getting done with not much one day goosing.
