Despite delivering investors losses of 66% over the past 3 years, PVA TePla (ETR:TPE) has been growing its earnings

PVA TePla AG (ETR:TPE) shareholders should be happy to see the share price up 18% in the last month. But that doesn't change the fact that the returns over the last three years have been disappointing. Tragically, the share price declined 66% in that time. So it's good to see it climbing back up. After all, could be that the fall was overdone.

Although the past week has been more reassuring for shareholders, they're still in the red over the last three years, so let's see if the underlying business has been responsible for the decline.

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 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).

During the unfortunate three years of share price decline, PVA TePla actually saw its earnings per share (EPS) improve by 21% 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.

It's worth taking a look at other metrics, because the EPS growth doesn't seem to match with the falling share price.

Revenue is actually up 22% 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 PVA TePla more closely, as sometimes stocks fall unfairly. This could present an opportunity.

A Different Perspective

PVA TePla shareholders are down 28% for the year, but the market itself is up 14%. 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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 1.4% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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 for instance, the ever-present spectre of investment risk. We've identified 1 warning sign with PVA TePla , and understanding them should be part of your investment process.
