It might be of some concern to shareholders to see the Chart Industries, Inc. (NYSE:GTLS) share price down 12% in the last month. On the bright side the share price is up over the last half decade. In that time, it is up 56%, which isn't bad, but is below the market return of 91%.

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Chart Industries' earnings per share are down 1.9% per year, despite strong share price performance over five years. The impact of extraordinary items on earnings, in the last year, partially explain the diversion.

By glancing at these numbers, we'd posit that the decline in earnings per share is not representative of how the business has changed over the years. Therefore, it's worth taking a look at other metrics to try to understand the share price movements.

In contrast revenue growth of 16% per year is probably viewed as evidence that Chart Industries is growing, a real positive. In that case, the company may be sacrificing current earnings per share to drive growth.

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business. So we recommend checking out this free report showing consensus forecasts

A Different Perspective

Chart Industries shareholders are down 5.0% for the year, but the market itself is up 22%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 9%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. It's always interesting to track share price performance over the longer term. But to understand Chart Industries better, we need to consider many other factors.
