Skyline Champion Corporation's (NYSE:SKY) price-to-earnings (or "P/E") ratio of 24.1x 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 9x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

With earnings that are retreating more than the market's of late, Skyline Champion has been very sluggish. It might be that many expect the dismal earnings performance to recover substantially, which has kept the P/E from collapsing. If not, then existing shareholders may be very nervous about the viability of the share price.

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

In order to justify its P/E ratio, Skyline Champion would need to produce impressive growth in excess of the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 53%. Still, the latest three year period has seen an excellent 247% overall rise in EPS, in spite of its unsatisfying short-term performance. 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.

Turning to the outlook, the next year should bring diminished returns, with earnings decreasing 11% as estimated by the six analysts watching the company. That's not great when the rest of the market is expected to grow by 11%.

With this information, we find it concerning that Skyline Champion is trading at a P/E higher than the market. It seems most investors are hoping for a turnaround in the company's business prospects, but the analyst cohort is not so confident this will happen. 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 Bottom Line On Skyline Champion's P/E

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

We've established that Skyline Champion currently trades on a much higher than expected P/E for a company whose earnings are forecast to decline. When we see a poor outlook with earnings heading backwards, we suspect the share price is at risk of declining, sending the high P/E lower. This places shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
