TheStreet Ratings team rates FUEL TECH INC as a Buy with a ratings score of B-. The team has this to say about their recommendation:

"We rate FUEL TECH INC (FTEK) a BUY. This is driven by several positive factors, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its revenue growth, largely solid financial position with reasonable debt levels by most measures, attractive valuation levels, expanding profit margins and solid stock price performance. We feel these strengths outweigh the fact that the company shows weak operating cash flow."
