CEPS PLC's (LON:CEPS) price-to-earnings (or "P/E") ratio of 18x might make it look like a sell right now compared to the market in the United Kingdom, where around half of the companies have P/E ratios below 15x and even P/E's below 9x are quite common. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.
For instance, CEPS' receding earnings in recent times would have to be some food for thought. 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.

The only time you'd be truly comfortable seeing a P/E as high as CEPS' is when the company's growth is on track to outshine the market.
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 33%. At least EPS has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.
Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 19% shows it's noticeably less attractive on an annualised basis.
In light of this, it's alarming that CEPS' 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 good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.
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.
We've established that CEPS 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.
Don't forget that there may be other risks. For instance, we've identified 3 warning signs for CEPS (1 can't be ignored) you should be aware of.
