In his latest article for Seeking Alpha, Validea CEO John Reese takes a look at a much-maligned oil refiner that his Guru Strategies think is big-time bargain.

Reese notes that oil refiners have been hit hard as Brent-WTI spreads have narrowed significantly, and have also been hit hard by broader economic fears, fears that declining gas prices will mean declining margins, and fears about tougher fuel standards. “All of that might make you want to dump shares of refiners as quickly as possible,” writes Reese. “But for my Guru Strategies, it’s music to their ears. These models, each of which is based on the approach of a different investing great, tend to be contrarian in nature. And because investors have a tendency to overreact, they often will step in and snatch up shares of unloved, beaten-down stocks whose fundamentals indicate they’ve been hit too hard. That’s the case right now with one major refiner, HollyFrontier Corp. (HFC), the Dallas-based firm that operates five complex refineries in the Midwest, Southwestern, and Rocky Mountain regions.”

Reese notes that three of his strategies — those he bases on the writings of Benjamin Graham, Joel Greenblatt, and Kenneth Fisher — recently issued a Trade Alert for HollyFrontier. Check out the article to see exactly what these top-performing models like about the refiner.
