The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on a lighter note, a good company can see its share price rise well over 100%. For example, the Sanmina Corporation (NASDAQ:SANM) share price has soared 122% in the last half decade. Most would be very happy with that.

Let's take a look at the underlying fundamentals over the longer term, and see if they've been consistent with shareholders returns.

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 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.

Over half a decade, Sanmina managed to grow its earnings per share at 18% a year. This EPS growth is remarkably close to the 17% average annual increase in the share price. That suggests that the market sentiment around the company hasn't changed much over that time. In fact, the share price seems to largely reflect the EPS growth.

The graphic below depicts how EPS has changed over time (unveil the exact values by clicking on the image).

A Different Perspective

Sanmina's TSR for the year was broadly in line with the market average, at 24%. That gain looks pretty satisfying, and it is even better than the five-year TSR of 17% per year. It is possible that management foresight will bring growth well into the future, even if the share price slows down. 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.
