How Do I Calculate A Price To Earnings Ratio?

P/E of 23.44 = £4.69 ÷ £0.20 (Based on the year to March 2019.)

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. That isn't necessarily good or bad, but a high P/E implies relatively high expectations of what a company can achieve in the future.

How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. 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.

Notably, discoverIE Group grew EPS by a whopping 34% in the last year. And earnings per share have improved by 18% annually, over the last five years. So we'd generally expect it to have a relatively high P/E ratio.

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

Don't forget that the P/E ratio considers market capitalization. So it won't reflect the advantage of cash, or disadvantage of debt. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

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 discoverIE Group's Debt Impact Its P/E Ratio?

discoverIE Group's net debt is 15% 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 Verdict On discoverIE Group's P/E Ratio

discoverIE Group has a P/E of 23.4. That's higher than the average in its market, which is 16.7. While the company does use modest debt, its recent earnings growth is superb. So on this analysis a high P/E ratio seems reasonable.
