It's been a soft week for MRC Global Inc. (NYSE:MRC) shares, which are down 12%. But over three years, the returns would have left most investors smiling After all, the share price is up a market-beating 72% in that time.

In light of the stock dropping 12% 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.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During three years of share price growth, MRC Global moved from a loss to profitability. That would generally be considered a positive, so we'd expect the share price to be up.
