Unpleasant Surprises Could Be In Store For Pfeiffer Vacuum Technology AG's (ETR:PFV) Shares

With a price-to-earnings (or "P/E") ratio of 24.6x Pfeiffer Vacuum Technology AG (ETR:PFV) may be sending bearish signals at the moment, given that almost half of all companies in Germany have P/E ratios under 16x and even P/E's lower than 10x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's as high as it is.

For instance, Pfeiffer Vacuum Technology's receding earnings in recent times would have to be some food for thought. One possibility is that the P/E is high because investors think the company will still do enough to outperform the broader market in the near future. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

There's an inherent assumption that a company should outperform the market for P/E ratios like Pfeiffer Vacuum Technology's to be considered reasonable.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 26%. Regardless, EPS has managed to lift by a handy 19% in aggregate from three years ago, thanks to the earlier period of growth. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been mostly respectable for the company.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 21% shows it's noticeably less attractive on an annualised basis.

With this information, we find it concerning that Pfeiffer Vacuum Technology is trading at a P/E higher than the market. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

The Key Takeaway

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our examination of Pfeiffer Vacuum Technology revealed its three-year earnings trends aren't impacting its high P/E anywhere near as much as we would have predicted, given they look worse than current market expectations. When we see weak earnings with slower than market growth, we suspect the share price is at risk of declining, sending the high P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.

Before you settle on your opinion, we've discovered 1 warning sign for Pfeiffer Vacuum Technology that you should be aware of.
