Cognex Corporation's (NASDAQ:CGNX) Price Is Out Of Tune With Earnings

With a price-to-earnings (or "P/E") ratio of 45.3x Cognex Corporation (NASDAQ:CGNX) 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 16x and even P/E's lower than 9x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

Cognex has been struggling lately as its earnings have declined faster than most other companies. One possibility is that the P/E is high because investors think the company will turn things around completely and accelerate past most others in the market. If not, then existing shareholders may be very nervous about the viability of the share price.

Does Growth Match The High P/E?

Cognex's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Retrospectively, the last year delivered a frustrating 26% decrease to the company's bottom line. This means it has also seen a slide in earnings over the longer-term as EPS is down 16% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Looking ahead now, EPS is anticipated to slump, contracting by 0.8% during the coming year according to the analysts following the company. That's not great when the rest of the market is expected to grow by 10%.

With this information, we find it concerning that Cognex 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. Only the boldest would assume these prices are sustainable as these declining earnings are likely to weigh heavily on the share price eventually.

The Final Word

Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

Our examination of Cognex'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. 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.

Many other vital risk factors can be found on the company's balance sheet. Our free balance sheet analysis for Cognex with six simple checks will allow you to discover any risks that could be an issue.
