Costain Group PLC (LON:COST) Surges 29% Yet Its Low P/E Is No Reason For Excitement
The Costain Group PLC (LON:COST) share price has done very well over the last month, posting an excellent gain of 29%. The last 30 days bring the annual gain to a very sharp 74%.
In spite of the firm bounce in price, Costain Group's price-to-earnings (or "P/E") ratio of 9.5x might still make it look like a buy right now compared to the market in the United Kingdom, where around half of the companies have P/E ratios above 17x and even P/E's above 30x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.
With earnings growth that's superior to most other companies of late, Costain Group has been doing relatively well. One possibility is that the P/E is low because investors think this strong earnings performance might be less impressive moving forward. 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.

How Is Costain Group's Growth Trending?
In order to justify its P/E ratio, Costain Group would need to produce sluggish growth that's trailing the market.
Taking a look back first, we see that the company grew earnings per share by an impressive 41% last year. The latest three year period has also seen an excellent 387% overall rise in EPS, aided by its short-term performance. So we can start by confirming that the company has done a great job of growing earnings over that time.
Turning to the outlook, the next three years should generate growth of 9.5% per year as estimated by the three analysts watching the company. With the market predicted to deliver 15% growth per annum, the company is positioned for a weaker earnings result.
In light of this, it's understandable that Costain Group's P/E sits below the majority of other companies. It seems most investors are expecting to see limited future growth and are only willing to pay a reduced amount for the stock.
The Final Word
Costain Group's stock might have been given a solid boost, but its P/E certainly hasn't reached any great heights. While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.
We've established that Costain Group maintains its low P/E on the weakness of its forecast growth being lower than the wider market, 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 these conditions improve, they will continue to form a barrier for the share price around these levels.
