The goal of this article is to teach you how to use price to earnings ratios (P/E ratios). We'll look at Arotech Corporation's (NASDAQ:ARTX) P/E ratio and reflect on what it tells us about the company's share price. Based on the last twelve months, Arotech's P/E ratio is 41.48. That is equivalent to an earnings yield of about 2.4%.

How Do I Calculate A Price To Earnings Ratio?

The formula for P/E is:

Price to Earnings Ratio = Share Price ÷ Earnings per Share (EPS)

Or for Arotech:

P/E of 41.48 = $2.93 ÷ $0.071 (Based on the trailing twelve months to December 2018.)

Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio implies that investors pay a higher price for the earning power of the business. All else being equal, it's better to pay a low price -- but as Warren Buffett said, 'It's far better to buy a wonderful company at a fair price than a fair company at a wonderful price.'

How Growth Rates Impact P/E Ratios

Earnings growth rates have a big influence on P/E ratios. Earnings growth means that in the future the 'E' will be higher. That means even if the current P/E is high, it will reduce over time if the share price stays flat. Then, a lower P/E should attract more buyers, pushing the share price up.

Arotech shrunk earnings per share by 74% over the last year. But over the longer term (5 years) earnings per share have increased by 3.1%.

How Does Arotech's P/E Ratio Compare To Its Peers?

The P/E ratio essentially measures market expectations of a company. You can see in the image below that the average P/E (21.8) for companies in the aerospace & defense industry is lower than Arotech's P/E.

Its relatively high P/E ratio indicates that Arotech shareholders think it will perform better than other companies in its industry classification. The market is optimistic about the future, but that doesn't guarantee future growth. So investors should delve deeper. I like to check if company insiders have been buying or selling.

Don't Forget: The P/E Does Not Account For Debt or Bank Deposits

The 'Price' in P/E reflects the market capitalization of the company. That means it doesn't take debt or cash into account. Theoretically, a business can improve its earnings (and produce a lower P/E in the future), by taking on debt (or spending its remaining cash).

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

Is Debt Impacting Arotech's P/E?

Arotech's net debt is 13% of its market cap. 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 Bottom Line On Arotech's P/E Ratio

Arotech trades on a P/E ratio of 41.5, which is above the US market average of 17.7. With some debt but no EPS growth last year, the market has high expectations of future profits.
