There wouldn't be many who think Flex Ltd.'s (NASDAQ:FLEX) price-to-earnings (or "P/E") ratio of 18.2x is worth a mention when the median P/E in the United States is similar at about 19x. While this might not raise any eyebrows, if the P/E ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

Recent times have been advantageous for Flex as its earnings have been rising faster than most other companies. It might be that many expect the strong earnings performance to wane, which has kept the P/E from rising. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's not quite in favour.

Is There Some Growth For Flex?

Flex's P/E ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the market.

If we review the last year of earnings growth, the company posted a terrific increase of 434%. As a result, it also grew EPS by 8.0% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been respectable for the company.

Turning to the outlook, the next three years should generate growth of 18% each year as estimated by the eight analysts watching the company. That's shaping up to be materially higher than the 11% per annum growth forecast for the broader market.

In light of this, it's curious that Flex's P/E sits in line with the majority of other companies. It may be that most investors aren't convinced the company can achieve future growth expectations.

What We Can Learn From Flex'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 Flex's analyst forecasts revealed that its superior earnings outlook isn't contributing to its P/E 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 pressure on the P/E ratio. At least the risk of a price drop looks to be subdued, but investors seem to think future earnings could see some volatility.

And what about other risks? Every company has them, and we've spotted 2 warning signs for Flex you should know about.
