Delta Air Lines, Inc. (NYSE:DAL) Might Not Be As Mispriced As It Looks After Plunging 26%

Delta Air Lines, Inc. (NYSE:DAL) shareholders won't be pleased to see that the share price has had a very rough month, dropping 26% and undoing the prior period's positive performance. Looking back over the past twelve months the stock has been a solid performer regardless, with a gain of 18%.

In spite of the heavy fall in price, Delta Air Lines may still be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 9.3x, since almost half of all companies in the United States have P/E ratios greater than 18x and even P/E's higher than 32x are not unusual. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Delta Air Lines hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. It seems that many are expecting the dour earnings performance to persist, which has repressed the P/E. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

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

Delta Air Lines' P/E ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 25%. However, a few very strong years before that means that it was still able to grow EPS by an impressive 1,124% in total over the last three years. So we can start by confirming that the company has generally done a very good job of growing earnings over that time, even though it had some hiccups along the way.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 16% per year over the next three years. That's shaping up to be materially higher than the 11% each year growth forecast for the broader market.

With this information, we find it odd that Delta Air Lines is trading at a P/E lower than the market. Apparently some shareholders are doubtful of the forecasts and have been accepting significantly lower selling prices.

The Final Word

Delta Air Lines' P/E has taken a tumble along with its share price. We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that Delta Air Lines 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.
