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 Coherent:

P/E of 26.25 = $137.12 ÷ $5.22 (Based on the year to June 2019.)

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. 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.'

NasdaqGS:COHR Price Estimation Relative to Market, August 12th 2019

Coherent'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

Generally speaking the rate of earnings growth has a profound impact on a company's P/E multiple. Earnings growth means that in the future the 'E' will be higher. And in that case, the P/E ratio itself will drop rather quickly. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.

Coherent's earnings per share fell by 48% in the last twelve months. But EPS is up 16% over the last 5 years.

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. Thus, the metric does not reflect cash or debt held by the company. 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).

Coherent's Balance Sheet

Net debt totals just 4.1% of Coherent's market cap. So it doesn't have as many options as it would with net cash, but its debt would not have much of an impact on its P/E ratio.

The Verdict On Coherent's P/E Ratio

Coherent's P/E is 26.3 which is above average (17.4) in its market. With some debt but no EPS growth last year, the market has high expectations of future profits.
