Despite an already strong run, Premier Energy PLC (BVB:PE) shares have been powering on, with a gain of 27% in the last thirty days. The last 30 days bring the annual gain to a very sharp 45%.
In spite of the firm bounce in price, Premier Energy's price-to-earnings (or "P/E") ratio of 7.7x might still make it look like a buy right now compared to the market in Romania, where around half of the companies have P/E ratios above 15x and even P/E's above 39x 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 limited.
Premier Energy certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

There's an inherent assumption that a company should underperform the market for P/E ratios like Premier Energy's to be considered reasonable.
If we review the last year of earnings growth, the company posted a terrific increase of 104%. However, this wasn't enough as the latest three year period has seen a very unpleasant 56% drop in EPS in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.
In contrast to the company, the rest of the market is expected to grow by 10% over the next year, which really puts the company's recent medium-term earnings decline into perspective.
In light of this, it's understandable that Premier Energy's P/E would sit below the majority of other companies. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.
The latest share price surge wasn't enough to lift Premier Energy's P/E close to the market median. 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 Premier Energy maintains its low P/E on the weakness of its sliding earnings over the medium-term, as expected. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
