When you buy a stock there is always a possibility that it could drop 100%. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. One great example is MasTec, Inc. (NYSE:MTZ) which saw its share price drive 110% higher over five years. Also pleasing for shareholders was the 28% gain in the last three months. But this move may well have been assisted by the reasonably buoyant market (up 13% in 90 days).

On the back of a solid 7-day performance, let's check what role the company's fundamentals have played in driving long term shareholder returns.

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 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.

MasTec has made a profit in the past. On the other hand, it reported a trailing twelve months loss, suggesting it isn't reliably profitable. So we might find other metrics can better explain the share price movements.

On the other hand, MasTec's revenue is growing nicely, at a compound rate of 13% over the last five years. It's quite possible that management are prioritizing revenue growth over EPS growth at the moment.

MasTec is well known by investors, and plenty of clever analysts have tried to predict the future profit levels. If you are thinking of buying or selling MasTec stock, you should check out this free report showing analyst consensus estimates for future profits.

A Different Perspective

While the broader market gained around 25% in the last year, MasTec shareholders lost 8.2%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 16% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
