Ken Kam follows 70,000+ stock pickers who run virtual portfolios on Marketocracy; he looks for stocks bought by the 'best' while being sold by the 'rest'. Here's two energy ideas.

"Complete Production Services (NYSE: CPX) is a mid-cap, Texas-based, Oil and Gas Equipment and Services company, that specializes on developing hydrocarbon reserves.

"They're involved with production, maintenance, optimization, testing, and handling services for well development; along with drilling and supplying products for oil companies. Its operations are located in the United States, Canada, Mexico and Singapore, along with some drilling rigs in northern Texas.

"The 'Best' investors began purchasing CPX in Mar. 2007 at $20 and then they purchased more in Nov. 2007 at $19. A few sold their shares in Feb. '08 at $19, but many held onto their shares and were quite fortunate, as the stock recently hit a high of $33.82.

"Perhaps the Best Investors wish for a bit more of that luck, as they have purchased more shares of CPX in the past two weeks. We have recently seen the 'Best' increase their holdings in the stock by 11% while the 'Rest' have decreased holdings by 25%.

"Bill Barrett Corp. (NYSE: BBG) is a Colorado-based, mid-cap company that specializes in oil and gas exploration and production. They have interests at the: Uinta Basin in Utah; Piceance Basin in Colorado; Powder River, Wind River and Big Horn Basins in Wyoming; and the Montana Overthrust in Montana.

"The 'Best' investors began purchasing Bill Barrett in Apr. 2005 at $29, and they kept purchasing more shares during that year. In Nov. '06 they turned around sold a lot of BBG at $30, only to purchase it again in Apr. of 2007 at $37.

"That bet has turned out well, as the stock recently hit a high of $59.52. Now, the Best investors have recently purchased more shares of BBG, increasing their holdings by 40% while the 'Rest' decreased their positions."
