Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What's happening: Industrial gas processing and storage equipment maker Chart Industries' (NASDAQ:GTLS) stock is up more than 19% Tuesday. 

Why it's happening: It's funny how Mr. Market can respond to earnings. The company released the results for its fourth-quarter and full-year 2014 this morning, and frankly, they weren't exactly blowout. Chart Industries reported sales and gross margin declines in two of its three business segments, and its guidance for 2015 included a major drop in earnings per share, largely due to foreign currency exchange issues and the potential for an extended cheap oil environment.

However, the company continues to take steps to position itself for the future, with major investments in manufacturing in China and the U.S. to participate in the expansion of natural gas development for transportation and industrial applications.
