Buying shares in the best businesses can build meaningful wealth for you and your family. While the best companies are hard to find, but they can generate massive returns over long periods. Just think about the savvy investors who held SDI Group plc (LON:SDI) shares for the last five years, while they gained 533%. And this is just one example of the epic gains achieved by some long term investors. It's down 2.4% in the last seven days. It really delights us to see such great share price performance for investors.

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

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Over half a decade, SDI Group managed to grow its earnings per share at 33% a year. This EPS growth is slower than the share price growth of 45% per year, over the same period. 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.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

A Different Perspective

SDI Group shareholders are down 12% for the year, but the market itself is up 1.2%. 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. On the bright side, long term shareholders have made money, with a gain of 45% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend.
