Energy-company stocks capture investor attention despite year-end portfolio distractions.

Energy-company IPOs have dominated the new-stock scene this month, launching seven of the 13 new U.S.-exchange listings through Dec. 15. The six others capturing investor interest as 2011 wanes and many portfolios are being righted for tax purposes are a social-gaming-service, fashion house Michael Kors Holdings Ltd., a REIT, a social-business software firm and two healthcare-industry operators.

Among the energy IPO pricings this month, onshore-U.S.-focused E&Ps and pipeline operators whet stock-buyers’ appetites.

-- Eric Mullins and Charles Adcock’s LRR Energy LP (NYSE: LRE) sold 9.4 million units at $19 each. Houston-based LRR has 30 million BOE of proved reserves in the Permian Basin, Midcontinent and Gulf Coast.

--Chesapeake Energy Corp.’s Chesapeake Granite Wash Trust (NYSE: CHKR) sold 20 million units at $19 each. It holds interests in production from a portion of Chesapeake’s Granite Wash-play leasehold in the Anadarko Basin.

Prior to pricings this week, Gabriele Sorbara, vice president, E&P research, for Caris & Co., forecast, “We believe these transactions will be well received by the market, given their exposure to oily plays, including the Permian Basin, the Eagle Ford shale and Niobrara, to name a few.”

Foutch’s Laredo Petroleum Holdings is particularly eye-catching, “given its exposure to the horizontal Wolfcamp/Cline shales in the Midland Basin. While Laredo’s IPO pricing and valuation should be positive for the Permian players—especially the horizontal Wolfcamp players—we believe this week's…flurry of IPO activity would bring excitement to the entire E&P sector into year-end.”
