The Petrol AD (BUL:PET) share price has fared very poorly over the last month, falling by a substantial 55%. The recent drop completes a disastrous twelve months for shareholders, who are sitting on a 62% loss during that time.
Even after such a large drop in price, Petrol AD's price-to-earnings (or "P/E") ratio of 2.6x might still make it look like a strong buy right now compared to the market in Bulgaria, where around half of the companies have P/E ratios above 22x and even P/E's above 49x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly reduced P/E.
For instance, Petrol AD's receding earnings in recent times would have to be some food for thought. One possibility is that the P/E is low because investors think the company won't do enough to avoid underperforming the broader market in the near future. 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 far underperform the market for P/E ratios like Petrol AD's to be considered reasonable.
Retrospectively, the last year delivered a frustrating 3.3% decrease to the company's bottom line. Unfortunately, that's brought it right back to where it started three years ago with EPS growth being virtually non-existent overall during that time. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.
This is in contrast to the rest of the market, which is expected to grow by 21% over the next year, materially higher than the company's recent medium-term annualised growth rates.
With this information, we can see why Petrol AD is trading at a P/E lower than the market. It seems most investors are expecting to see the recent limited growth rates continue into the future and are only willing to pay a reduced amount for the stock.
Having almost fallen off a cliff, Petrol AD's share price has pulled its P/E way down as well. 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.
As we suspected, our examination of Petrol AD revealed its three-year earnings trends are contributing to its low P/E, given they look worse than current market expectations. 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.
