Some Shareholders Feeling Restless Over Costco Wholesale Corporation's (NASDAQ:COST) P/E Ratio

With a price-to-earnings (or "P/E") ratio of 36.4x Costco Wholesale Corporation (NASDAQ:COST) may be sending very bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 13x and even P/E's lower than 7x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

Costco Wholesale certainly has been doing a good job lately as it's been growing earnings more than most other companies. The P/E is probably high because investors think this strong earnings performance will continue. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Costco Wholesale's Growth Trending?

The only time you'd be truly comfortable seeing a P/E as steep as Costco Wholesale's is when the company's growth is on track to outshine the market decidedly.

Taking a look back first, we see that the company grew earnings per share by an impressive 17% last year. Pleasingly, EPS has also lifted 59% in aggregate from three years ago, thanks to the last 12 months of growth. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Turning to the outlook, the next three years should generate growth of 11% each year as estimated by the analysts watching the company. Meanwhile, the rest of the market is forecast to expand by 9.6% per year, which is not materially different.

In light of this, it's curious that Costco Wholesale's P/E sits above the majority of other companies. Apparently many investors in the company are more bullish than analysts indicate and aren't willing to let go of their stock right now. Although, additional gains will be difficult to achieve as this level of earnings growth is likely to weigh down the share price eventually.

What We Can Learn From Costco Wholesale'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.

Our examination of Costco Wholesale's analyst forecasts revealed that its market-matching earnings outlook isn't impacting its high P/E as much as we would have predicted. When we see an average earnings outlook with market-like growth, we suspect the share price is at risk of declining, sending the high P/E lower. Unless these conditions improve, it's challenging to accept these prices as being reasonable.
