With a price-to-earnings (or "P/E") ratio of 11.7x Weatherford International plc (NASDAQ:WFRD) may be sending bullish signals at the moment, given that almost half of all companies in the United States have P/E ratios greater than 20x and even P/E's higher than 36x 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 limited.

Recent times have been advantageous for Weatherford International as its earnings have been rising faster than most other companies. One possibility is that the P/E is low because investors think this strong earnings performance might be less impressive moving forward. 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 out of favour.

Does Growth Match The Low P/E?

There's an inherent assumption that a company should underperform the market for P/E ratios like Weatherford International's to be considered reasonable.

Taking a look back first, we see that the company grew earnings per share by an impressive 50% last year. Still, EPS has barely risen at all from three years ago in total, which is not ideal. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Shifting to the future, estimates from the eight analysts covering the company suggest earnings should grow by 6.3% per year over the next three years. With the market predicted to deliver 11% growth per year, the company is positioned for a weaker earnings result.

In light of this, it's understandable that Weatherford International's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

What We Can Learn From Weatherford International'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.
