The truth is that if you invest for long enough, you're going to end up with some losing stocks. But the long term shareholders of EPAM Systems, Inc. (NYSE:EPAM) have had an unfortunate run in the last three years. So they might be feeling emotional about the 62% share price collapse, in that time. And more recent buyers are having a tough time too, with a drop of 30% in the last year. The falls have accelerated recently, with the share price down 41% in the last three months. We note that the company has reported results fairly recently; and the market is hardly delighted. You can check out the latest numbers in our company report.

After losing 5.9% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the unfortunate three years of share price decline, EPAM Systems actually saw its earnings per share (EPS) improve by 5.9% per year. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Or else the company was over-hyped in the past, and so its growth has disappointed.

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.

Revenue is actually up 16% over the three years, so the share price drop doesn't seem to hinge on revenue, either. This analysis is just perfunctory, but it might be worth researching EPAM Systems more closely, as sometimes stocks fall unfairly. This could present an opportunity.

It's probably worth noting that the CEO is paid less than the median at similar sized 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

Investors in EPAM Systems had a tough year, with a total loss of 30%, against a market gain of about 28%. 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 2% 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Consider risks, for instance.
