CVR Energy (NYSE:CVI) has more than doubled in price since Carl Icahn purchased a majority stake in the company. It has joined other mid-continent refiners as the top energy performers in 2012 as the group took advantage of discounted feedstocks to increase refining margins to impressive highs. The new holding company looks to continue its run as long as WTI and Western Canadian Select crude benchmarks remain significantly discounted to the international Brent price.
