WESCO International, Inc.'s (NYSE:WCC) price-to-earnings (or "P/E") ratio of 12.5x might make it look like a buy right now compared to the market in the United States, where around half of the companies have P/E ratios above 17x and even P/E's above 32x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

With earnings that are retreating more than the market's of late, WESCO International has been very sluggish. It seems that many are expecting the dismal earnings performance to persist, which has repressed the P/E. 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 the earnings slide doesn't get any worse if your plan is to pick up some stock while it's out of favour.

Is There Any Growth For WESCO International?

WESCO International's P/E ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 24%. However, a few very strong years before that means that it was still able to grow EPS by an impressive 636% 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.

Turning to the outlook, the next three years should generate growth of 13% per annum as estimated by the twelve analysts watching the company. Meanwhile, the rest of the market is forecast to only expand by 10% per annum, which is noticeably less attractive.

With this information, we find it odd that WESCO International is trading at a P/E lower than the market. It looks like most investors are not convinced at all that the company can achieve future growth expectations.

The Key Takeaway

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 WESCO International's analyst forecasts revealed that its superior earnings outlook isn't contributing to its P/E anywhere near as much as we would have predicted. When we see a strong earnings outlook with faster-than-market growth, we assume potential risks are what might be placing significant pressure on the P/E ratio. At least price risks look to be very low, but investors seem to think future earnings could see a lot of volatility.
