What Planoptik AG's (ETR:P4O) P/E Is Not Telling You

With a price-to-earnings (or "P/E") ratio of 25.2x Planoptik AG (ETR:P4O) may be sending bearish signals at the moment, given that almost half of all companies in Germany have P/E ratios under 19x and even P/E's lower than 11x 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.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

As an illustration, earnings have deteriorated at Planoptik over the last year, which is not ideal at all. 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. If not, then existing shareholders may be quite nervous about the viability of the share price.

What Are Growth Metrics Telling Us About The High P/E?

Planoptik's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 58%. The last three years don't look nice either as the company has shrunk EPS by 3.1% in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

In contrast to the company, the rest of the market is expected to grow by 22% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we find it concerning that Planoptik is trading at a P/E higher than the market. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

What We Can Learn From Planoptik's P/E?

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Planoptik revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely to support such positive sentiment for long. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
