There's Reason For Concern Over Keyrus S.A.'s (EPA:ALKEY) Massive 40% Price Jump

Keyrus S.A. (EPA:ALKEY) shareholders have had their patience rewarded with a 40% share price jump in the last month. The last month tops off a massive increase of 124% in the last year.

Since its price has surged higher, Keyrus' price-to-earnings (or "P/E") ratio of 44.4x might make it look like a strong sell right now compared to the market in France, where around half of the companies have P/E ratios below 17x and even P/E's below 9x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

For example, consider that Keyrus' financial performance has been poor lately as its earnings have been in decline. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. 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 far outperform the market for P/E ratios like Keyrus' 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 9.3%. This has erased any of its gains during the last three years, with practically no change in EPS being achieved in total. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

This is in contrast to the rest of the market, which is expected to grow by 19% over the next year, materially higher than the company's recent medium-term annualised growth rates.

With this information, we find it concerning that Keyrus is trading at a P/E higher than the market. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. 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 Final Word

Keyrus' P/E is flying high just like its stock has during the last month. 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.

We've established that Keyrus currently trades on a much higher than expected P/E since its recent three-year growth is lower than the wider market forecast. Right now we are increasingly uncomfortable with the high P/E as this earnings performance isn't likely 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.
