The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. One great example is Pro-Dex, Inc. (NASDAQ:PDEX) which saw its share price drive 136% higher over five years. But it's down 6.2% in the last week. But this could be related to the soft market, with stocks selling off around 4.4% in the last week.

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.

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.

Pro-Dex's earnings per share are down 3.3% per year, despite strong share price performance over five years.

So it's hard to argue that the earnings per share are the best metric to judge the company, as it may not be optimized for profits at this point. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

In contrast revenue growth of 15% per year is probably viewed as evidence that Pro-Dex is growing, a real positive. It's quite possible that management are prioritizing revenue growth over EPS growth at the moment.

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

We regret to report that Pro-Dex shareholders are down 28% for the year. Unfortunately, that's worse than the broader market decline of 21%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. On the bright side, long term shareholders have made money, with a gain of 19% 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. 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. Consider risks, for instance. Every company has them, and we've spotted 2 warning signs for Pro-Dex you should know about.
