With a price-to-earnings (or "P/E") ratio of 7.8x Globe Life Inc. (NYSE:GL) may be sending very bullish signals at the moment, given that almost half of all companies in the United States have P/E ratios greater than 18x and even P/E's higher than 33x are not unusual. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

Globe Life certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. It might be that many expect the strong earnings performance to degrade substantially, possibly more than the market, which has repressed the P/E. 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.

What Are Growth Metrics Telling Us About The Low P/E?

Globe Life's P/E ratio would be typical for a company that's expected to deliver very poor growth or even falling earnings, and importantly, perform much worse than the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 50% last year. Pleasingly, EPS has also lifted 57% in aggregate from three years ago, thanks to the last 12 months of growth. So we can start by confirming that the company has done a great job of growing earnings over that time.

Shifting to the future, estimates from the eight analysts covering the company suggest earnings should grow by 11% per annum over the next three years. Meanwhile, the rest of the market is forecast to expand by 10% per annum, which is not materially different.

In light of this, it's peculiar that Globe Life's P/E sits below the majority of other companies. It may be that most investors are not convinced the company can achieve future growth expectations.

The Key Takeaway

It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that Globe Life currently trades on a lower than expected P/E since its forecast growth is in line with the wider market. When we see an average earnings outlook with market-like growth, we assume potential risks are what might be placing pressure on the P/E ratio. It appears some are indeed anticipating earnings instability, because these conditions should normally provide more support to the share price.
