How Does AAR's (NYSE:AIR) P/E Compare To Its Industry, After The Share Price Drop?

In this article:

To the annoyance of some shareholders, AAR (NYSE:AIR) shares are down a considerable 32% in the last month. The recent drop has obliterated the annual return, with the share price now down 11% over that longer period.

Assuming nothing else has changed, a lower share price makes a stock more attractive to potential buyers. While the market sentiment towards a stock is very changeable, in the long run, the share price will tend to move in the same direction as earnings per share. The implication here is that long term investors have an opportunity when expectations of a company are too low. Perhaps the simplest way to get a read on investors' expectations of a business is to look at its Price to Earnings Ratio (PE Ratio). Investors have optimistic expectations of companies with higher P/E ratios, compared to companies with lower P/E ratios.

Its relatively low P/E ratio indicates that AAR shareholders think it will struggle to do as well as other companies in its industry classification. Since the market seems unimpressed with AAR, it's quite possible it could surprise on the upside. You should delve deeper. I like to check if company insiders have been buying or selling.

How Growth Rates Impact P/E Ratios

Earnings growth rates have a big influence on P/E ratios. That's because companies that grow earnings per share quickly will rapidly increase the 'E' in the equation. That means even if the current P/E is high, it will reduce over time if the share price stays flat. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

AAR increased earnings per share by an impressive 15% over the last twelve months. And earnings per share have improved by 13% annually, over the last five years. With that performance, you might expect an above average P/E ratio.

A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. So it won't reflect the advantage of cash, or disadvantage of debt. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

Spending on growth might be good or bad a few years later, but the point is that the P/E ratio does not account for the option (or lack thereof).

How Does AAR's Debt Impact Its P/E Ratio?

AAR has net debt worth 15% of its market capitalization. This could bring some additional risk, and reduce the number of investment options for management; worth remembering if you compare its P/E to businesses without debt.

The Verdict On AAR's P/E Ratio

AAR trades on a P/E ratio of 11.5, which is below the US market average of 15.1. The EPS growth last year was strong, and debt levels are quite reasonable. If the company can continue to grow earnings, then the current P/E may be unjustifiably low. What can be absolutely certain is that the market has become significantly less optimistic about AAR over the last month, with the P/E ratio falling from 16.9 back then to 11.5 today. For those who don't like to trade against momentum, that could be a warning sign, but a contrarian investor might want to take a closer look.

Investors should be looking to buy stocks that the market is wrong about. If the reality for a company is not as bad as the P/E ratio indicates, then the share price should increase as the market realizes this. So this free visualization of the analyst consensus on future earnings could help you make the right decision about whether to buy, sell, or hold.

Of course, you might find a fantastic investment by looking at a few good candidates. So take a peek at this free list of companies with modest (or no) debt, trading on a P/E below 20.
