When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on the bright side, you can make far more than 100% on a really good stock. For example, the Sanmina Corporation (NASDAQ:SANM) share price has soared 195% in the last half decade. Most would be very happy with that. Also pleasing for shareholders was the 16% gain in the last three months. The company reported its financial results recently; you can catch up on the latest numbers by reading our company report.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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.

Over half a decade, Sanmina managed to grow its earnings per share at 16% a year. This EPS growth is lower than the 24% average annual increase in the share price. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth.

A Different Perspective

It's good to see that Sanmina has rewarded shareholders with a total shareholder return of 46% in the last twelve months. Since the one-year TSR is better than the five-year TSR (the latter coming in at 24% per year), it would seem that the stock's performance has improved in recent times. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
