NWTR has it's debts under control unlike most other small oil stocks that generate tons of revenue but are bleeding money. It's not profitable to drill when crude prices are cheap but with crude recovering the sentiment is changing and now these are the hottest stocks to own.
Take a look at SandyRidge Energy. They have over 1.5 billion annual revenue but they lost almost 3 billion the past 3 quarters yet their share price jumped from 3 cents to 14 in the last month. Revenue and losses mean nothing when it comes to oil stocks. You're buying into the potential and right now the sentiment is that oil stocks are the hottest thing right now.
