One of the most fun aspects of picking stocks and doing research on investments is the moment you come across a company that seems to make loads of sense but for some reason it hasn't got traction from the rest of investment world. That happy place is where you will find Ultra Petroleum (NASDAQ:UPL), and it is why Ultra made our list of favorite stocks in 2013.

One of the reasons that Ultra continues to fly under the radar is that it is a generally misunderstood natural gas producer. Unlike its other natural gas-heavy producing peers such as Cabot Oil & Gas (NYSE:COG) or Exco Resources (NYSE:XCO), a majority of Ultra's natural gas production doesn't come from shale gas. Instead, most of the company's production comes from the Pinedale fields in Wyoming, where wells are cheap to drill and have a longer shelf life.
