How Do I Calculate A Price To Earnings Ratio?

The formula for price to earnings is:

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

P/E of 36.77 = £11.15 ÷ £0.30 (Based on the trailing twelve months to December 2018.)

Is A High Price-to-Earnings Ratio Good?

The higher the P/E ratio, the higher the price tag of a business, relative to its trailing earnings. 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 Does Gamma Communications's P/E Ratio Compare To Its Peers?

AIM:GAMA Price Estimation Relative to Market, August 8th 2019

Gamma Communications's P/E tells us that market participants think the company will perform better than its industry peers, going forward. Clearly the market expects growth, but it isn't guaranteed. So investors should always consider the P/E ratio alongside other factors, such as whether company directors have been buying shares.

How Growth Rates Impact P/E Ratios

Earnings growth rates have a big influence on P/E ratios. If earnings are growing quickly, then the 'E' in the equation will increase faster than it would otherwise. That means unless the share price increases, the P/E will reduce in a few years. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.

It's great to see that Gamma Communications grew EPS by 24% in the last year. And earnings per share have improved by 24% 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

The 'Price' in P/E reflects the market capitalization of the company. That means it doesn't take debt or cash into account. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.

Gamma Communications's Balance Sheet

Gamma Communications has net cash of UK£36m. That should lead to a higher P/E than if it did have debt, because its strong balance sheets gives it more options.

The Bottom Line On Gamma Communications's P/E Ratio

Gamma Communications trades on a P/E ratio of 36.8, which is above its market average of 15.9. With cash in the bank the company has plenty of growth options -- and it is already on the right track. Therefore it seems reasonable that the market would have relatively high expectations of the company
