In this edition, energy analysts Joel South and Taylor Muckerman talk about CVR Energy (NYSE: CVI) which makes came in as our No. 1 top-performing energy stock in 2012.

While the general dynamics of mid-continent refiners, cheap access to WTI crude, help CRV Energy gain more than 145% YTD, the story starts with Carl Icahn.

After putting his stamp on the company, Icahn watched as the CVR Energy moved higher as the company's crude refiners and the company's MLP, CVR Partners (NYSE: UAN) performed at historic levels.
