On CAPS, 96% of the 848 members who have rated ATP believe the stock will outperform the S&P 500 going forward. These bulls include CanadaDreamer and All-Star mrindependent, who is ranked in the top 1% of our community.

Late last month, CanadaDreamer brought the stock's powerful catalyst to our community's attention:

[ATP] trades at significant discount to sector averages and peer group metrics. Debt is an issue, but should be quickly resolved once cash flow from Telemark begins in Q1. Once the market is comfortable with production rates and cash flows, [ATP] will see a significant rerating.

In a pitch from two days ago, mrindependent echoes that enthusiasm. Here's an excerpt:

Some highlights of the February 2 press release include the company’s prediction that production will DOUBLE in 2010 and the company’s statement that the reserve replacement ratio for 2009 was 376%. Wow! ... The company’s presentations explain how the company is different from other oil and gas producers in two significant ways: (1) the company only acquires properties with proven reserves, which leads to a 98% drilling success rate and (2) the company organizes its drilling process in “hubs”. By using hubs, the company is able to achieve better economics and growth. ... Although long-term debt is high at $1.2 billion, there is no solvency concern because the company has wonderful profitability expectations and $317 million of cash on hand.
