Over on CAPS, fully 986 of the 1,023 members who have rated Fuel Tech -- some 96% -- believe the stock will outperform the S&P 500 going forward. These bulls include CAPS All-Star whoILMnc and LTContrarian.

Earlier this week, whoILMnc touched on the stock's long-term potential: "If coal has the future I think it does, even though very speculative, it is hard to see how [Fuel Tech] will not share in it."

In an earlier pitch from last month, LTContrarian agrees, stressing Fuel Tech's tantalizing tailwinds:

Although this company's stock price will likely be choppy over the next 6-12 months, right now is probably a great entry point for anyone interested in a long term position. Demographic trends are heavily in Fuel Tek's favor. Management is very solid and the company is becoming the gold standard in the industry with excellent proprietary products. The fact that China will be building approximately 1 coal plant per day into the forseeable future certainly bodes well for Fuel Tek going forward.
