Grenobloise d'Electronique et d'Automatismes Société Anonyme's (EPA:GEA) Share Price Not Quite Adding Up

When close to half the companies in France have price-to-earnings ratios (or "P/E's") below 16x, you may consider Grenobloise d'Electronique et d'Automatismes Société Anonyme (EPA:GEA) as a stock to avoid entirely with its 58.4x P/E ratio. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

As an illustration, earnings have deteriorated at Grenobloise d'Electronique et d'Automatismes Société Anonyme 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.

Does Growth Match The High P/E?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Grenobloise d'Electronique et d'Automatismes Société Anonyme's to be considered reasonable.

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 31%. The last three years don't look nice either as the company has shrunk EPS by 43% in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 18% shows it's an unpleasant look.

In light of this, it's alarming that Grenobloise d'Electronique et d'Automatismes Société Anonyme's P/E sits above the majority of other companies. 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 Bottom Line On Grenobloise d'Electronique et d'Automatismes Société Anonyme's P/E

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 Grenobloise d'Electronique et d'Automatismes Société Anonyme 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.

Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
