When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") above 18x, you may consider Metallus Inc. (NYSE:MTUS) as an attractive investment with its 11.6x P/E ratio. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

With its earnings growth in positive territory compared to the declining earnings of most other companies, Metallus has been doing quite well of late. One possibility is that the P/E is low because investors think the company's earnings are going to fall away like everyone else's soon. 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.

Keen to find out how analysts think Metallus' future stacks up against the industry? In that case, our free report is a great place to start.

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

There's an inherent assumption that a company should underperform the market for P/E ratios like Metallus' to be considered reasonable.

Retrospectively, the last year delivered an exceptional 93% gain to the company's bottom line. However, the latest three year period hasn't been as great in aggregate as it didn't manage to provide any growth at all. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Looking ahead now, EPS is anticipated to slump, contracting by 2.6% during the coming year according to the three analysts following the company. That's not great when the rest of the market is expected to grow by 14%.

In light of this, it's understandable that Metallus' 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. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.

What We Can Learn From Metallus' P/E?

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.

As we suspected, our examination of Metallus' analyst forecasts revealed that its outlook for shrinking earnings is contributing to its low P/E. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.
