Phillips 66 (NYSE:PSX) has been nothing short of spectacular since splitting off from ConocoPhillips (NYSE:COP) earlier this year. The refiner has made our list of top performing energy stocks in 2012 with a stock price appreciation of 60% year to date. While the sector as a whole was buoyed by access to cheap WTI oil in North America, Phillips 66 stands out as a long-term winner by using excess cash flows to build out its successful chemicals and midstream division. Shareholders have been adequately rewarded while the company increased its dividend twice this past year, in addition to enacting a lofty $2 billion share repurchasing program.
