On CAPS, 97% of the 1,085 members who have rated Ultra believe the stock will outperform the S&P 500 going forward. These bulls include All-Star unicornhunter7, who is ranked in the top 5% of our community, and Ak66.

Just last week, unicornhunter7 tapped Ultra as a rather natural selection: "It may not happen this year, or next year, but natural gas prices will go up. I would rather buy the stock now and wait, rather than pay more later."

Ultra's status as one of North America's lowest-cost producers makes it a particularly attractive bet on higher natural gas prices. Thanks in large part to an enviable position in Wyoming's Green River Basin, Ultra's trailing-12-month operating margin (90.6%) easily tops that of rivals EOG (7.4%), Cabot (22.4%), and Petrohawk (34%), as well as other natural gas plays like Chesapeake Energy (NYSE: CHK) (17.5%) and Anadarko (NYSE: APC) (25.7%).

CAPS member Ak66 elaborates on Ultra's cost advantage:

Like everyone else, I can't see the future. This company has much more to the upside than the downside. It can out-wait more expensive producers, and when prices turn around it will be in a great position. I do not know the future, but I do know that it will require energy. Gas is one of the best options at the table for the next 30 years.
