With a price-to-earnings (or "P/E") ratio of 20.7x Sturm, Ruger & Company, Inc. (NYSE:RGR) may be sending bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 17x and even P/E's lower than 10x are not unusual. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

For example, consider that Sturm Ruger's financial performance has been poor lately as its earnings have been in decline. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Sturm Ruger's Growth Trending?

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

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 51%. This means it has also seen a slide in earnings over the longer-term as EPS is down 75% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 15% shows it's an unpleasant look.

With this information, we find it concerning that Sturm Ruger is trading at a P/E higher than the market. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

What We Can Learn From Sturm Ruger's P/E?

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

Our examination of Sturm Ruger revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely to support such positive sentiment for long. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
