How Do You Calculate A P/E Ratio?

The formula for P/E is:

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

Or for Aggregated Micro Power Holdings:

P/E of 51.06 = £0.95 ÷ £0.019 (Based on the year to September 2018.)

Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that investors are paying a higher price for each £1 of company 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 Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. 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. A lower P/E should indicate the stock is cheap relative to others — and that may attract buyers.

Most would be impressed by Aggregated Micro Power Holdings earnings growth of 11% in the last year. And it has bolstered its earnings per share by 57% per year over the last five years. So one might expect an above average P/E ratio.

Its relatively high P/E ratio indicates that Aggregated Micro Power Holdings shareholders think it will perform better than other companies in its industry classification. 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.

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

It’s important to note that the P/E ratio considers the market capitalization, not the enterprise value. In other words, it does not consider any debt or cash that the company may have on the balance sheet. 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.

Is Debt Impacting Aggregated Micro Power Holdings’s P/E?

Aggregated Micro Power Holdings’s net debt is 18% of its market cap. That’s enough debt to impact the P/E ratio a little; so keep it in mind if you’re comparing it to companies without debt.

The Verdict On Aggregated Micro Power Holdings’s P/E Ratio

Aggregated Micro Power Holdings has a P/E of 51.1. That’s significantly higher than the average in the GB market, which is 15.6. Its debt levels do not imperil its balance sheet and it has already proven it can grow. So it is not surprising the market is probably extrapolating recent growth well into the future, reflected in the relatively high P/E ratio.
