If oil prices stabilize in 2018, investors may find themselves eyeing refinery companies. This potential move has HollyFrontier Corp HFC on Argus Research's radar. The Analyst Argus Research Company's Bill Selesky upgraded HollyFrontier's stock rating from Hold to Buy with a $53 price target on Monday morning.The Thesis HollyFrontier is an independent refiner and marketer that owns multiple refineries. Production averaged 454,790 barrels per day in the third quarter, up 3 percent from a year ago, Selesky said in a research report. If the price of oil stabilizes in the $50 to $60 range it will not only help boost the company's margin profile, but contribute to diminishing inventory levels of crude oil, gasoline, and diesel products.
