Cirrus Logic, Inc.'s (NASDAQ:CRUS) price-to-earnings (or "P/E") ratio of 24.8x might make it look like a sell right now compared to the market in the United States, where around half of the companies have P/E ratios below 17x and even P/E's below 10x are quite common. However, the P/E might be high 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, Cirrus Logic has been doing quite well of late. It seems that many are expecting the company to continue defying the broader market adversity, which has increased investors' willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

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

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

If we review the last year of earnings growth, the company posted a terrific increase of 103%. The latest three year period has also seen an excellent 51% overall rise in EPS, aided by its short-term performance. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

Turning to the outlook, the next year should bring diminished returns, with earnings decreasing 5.7% as estimated by the six analysts watching the company. That's not great when the rest of the market is expected to grow by 15%.

In light of this, it's alarming that Cirrus Logic's P/E sits above the majority of other companies. Apparently many investors in the company reject the analyst cohort's pessimism and aren't willing to let go of their stock at any price. There's a very good chance these shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the negative growth outlook.

The Final Word

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 Cirrus Logic's analyst forecasts revealed that its outlook for shrinking earnings isn't impacting its high P/E anywhere near as much as we would have predicted. Right now we are increasingly uncomfortable with the high P/E as the predicted future earnings are highly unlikely to support such positive sentiment for long. This places shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
