With a price-to-earnings (or "P/E") ratio of 10.8x Sonic Automotive, Inc. (NYSE:SAH) 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 17x and even P/E's higher than 32x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

Sonic Automotive 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.

Is There Any Growth For Sonic Automotive?

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

Taking a look back first, we see that the company grew earnings per share by an impressive 383% last year. EPS has also lifted 6.3% in aggregate from three years ago, mostly thanks to the last 12 months of growth. So we can start by confirming that the company has actually done a good job of growing earnings over that time.

Looking ahead now, EPS is anticipated to climb by 20% each year during the coming three years according to the seven analysts following the company. With the market only predicted to deliver 9.9% per year, the company is positioned for a stronger earnings result.

In light of this, it's peculiar that Sonic Automotive's P/E sits below the majority of other companies. Apparently some shareholders are doubtful of the forecasts and have been accepting significantly lower selling prices.

The Key Takeaway

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.

We've established that Sonic Automotive currently trades on a much lower than expected P/E since its forecast growth is higher than the wider market. There could be some major unobserved threats to earnings preventing the P/E ratio from matching the positive outlook. It appears many are indeed anticipating earnings instability, because these conditions should normally provide a boost to the share price.

Before you settle on your opinion, we've discovered 2 warning signs for Sonic Automotive (1 is a bit unpleasant!) that you should be aware of.

It's important to make sure you look for a great company, not just the first idea you come across. So take a peek at this free list of interesting companies with strong recent earnings growth (and a low P/E).
