What Compagnie de Saint-Gobain S.A.'s (EPA:SGO) P/E Is Not Telling You

With a median price-to-earnings (or "P/E") ratio of close to 15x in France, you could be forgiven for feeling indifferent about Compagnie de Saint-Gobain S.A.'s (EPA:SGO) P/E ratio of 13.4x. While this might not raise any eyebrows, if the P/E ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

Compagnie de Saint-Gobain has been struggling lately as its earnings have declined faster than most other companies. It might be that many expect the dismal earnings performance to revert back to market averages soon, which has kept the P/E from falling. If you still like the company, you'd want its earnings trajectory to turn around before making any decisions. Or at the very least, you'd be hoping it doesn't keep underperforming if your plan is to pick up some stock while it's not in favour.

What Are Growth Metrics Telling Us About The P/E?

The only time you'd be comfortable seeing a P/E like Compagnie de Saint-Gobain's is when the company's growth is tracking the market closely.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 9.9%. However, a few very strong years before that means that it was still able to grow EPS by an impressive 525% in total over the last three years. So we can start by confirming that the company has generally done a very good job of growing earnings over that time, even though it had some hiccups along the way.

Looking ahead now, EPS is anticipated to climb by 10% per year during the coming three years according to the analysts following the company. Meanwhile, the rest of the market is forecast to expand by 14% per annum, which is noticeably more attractive.

In light of this, it's curious that Compagnie de Saint-Gobain's P/E sits in line with the majority of other companies. It seems most investors are ignoring the fairly limited growth expectations and are willing to pay up for exposure to the stock. Maintaining these prices will be difficult to achieve as this level of earnings growth is likely to weigh down the shares eventually.

The Bottom Line On Compagnie de Saint-Gobain's P/E

It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of Compagnie de Saint-Gobain's analyst forecasts revealed that its inferior earnings outlook isn't impacting its P/E as much as we would have predicted. When we see a weak earnings outlook with slower than market growth, we suspect the share price is at risk of declining, sending the moderate P/E lower. This places shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
