These lackluster results are probably because of recent pullbacks in oil prices US light, sweet crude oil futures closed on Friday at $73.25 a barrel after ending as high as $77.03 just a few weeks ago. But many oil stocks are doing just fine. Exxon Mobil Corp the world's largest public oil company, shot to an all-time high after it reported a quarterly profit on Thursday of more than $10 billion. Three companies that made their debuts in January Western Refining Inc Linn Energy LLC and Calumet Specialty Products Partners LP traded above their offering price Friday. Calumet, which priced 6.45 million shares at $21.50, was up more than 40 percent from the offering price, trading at $30.11 on Friday. And oil and gas exploration company GeoMet Inc priced at the bottom of a forecast range on Thursday, but closed up 9.7 percent in its Friday debut. As long as oil prices are high, there should be plenty of initial public offerings in the sector, analysts said.
