What Revoil S.A.'s (ATH:REVOIL) 26% Share Price Gain Is Not Telling You

The Revoil S.A. (ATH:REVOIL) share price has done very well over the last month, posting an excellent gain of 26%. Taking a wider view, although not as strong as the last month, the full year gain of 11% is also fairly reasonable.

After such a large jump in price, Revoil may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 20.4x, since almost half of all companies in Greece have P/E ratios under 11x and even P/E's lower than 9x are not unusual. 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 Revoil 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. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Revoil's Growth Trending?

The only time you'd be truly comfortable seeing a P/E as steep as Revoil's is when the company's growth is on track to outshine the market decidedly.

Retrospectively, the last year delivered a frustrating 63% decrease to the company's bottom line. This means it has also seen a slide in earnings over the longer-term as EPS is down 34% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 7.3% shows it's an unpleasant look.

In light of this, it's alarming that Revoil'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. 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 Revoil's P/E?

Shares in Revoil have built up some good momentum lately, which has really inflated its P/E. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

Our examination of Revoil 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. 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.
