It might seem bad, but the worst that can happen when you buy a stock (without leverage) is that its share price goes to zero. But when you pick a company that is really flourishing, you can make more than 100%. For instance the MRC Global Inc. (NYSE:MRC) share price is 101% higher than it was three years ago. Most would be happy with that. It's also good to see the share price up 16% over the last quarter. This could be related to the recent financial results, released recently - you can catch up on the most recent data by reading our company report.

In light of the stock dropping 7.2% in the past week, we want to investigate the longer term story, and see if fundamentals have been the driver of the company's positive three-year return.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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.

During three years of share price growth, MRC Global moved from a loss to profitability. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

A Different Perspective

Investors in MRC Global had a tough year, with a total loss of 9.2%, against a market gain of about 10%. 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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 6% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround.
