How Do I Calculate A Price To Earnings Ratio?

The formula for price to earnings is:

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

Or for nLIGHT:

P/E of 74.68 = $18.6 ÷ $0.25 (Based on the trailing twelve months to March 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. 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. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

nLIGHT shrunk earnings per share by 42% over the last year.

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

One good way to get a quick read on what market participants expect of a company is to look at its P/E ratio. As you can see below, nLIGHT has a much higher P/E than the average company (18.6) in the electronic industry.

NasdaqGS:LASR Price Estimation Relative to Market, June 14th 2019

Its relatively high P/E ratio indicates that nLIGHT 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.

Remember: P/E Ratios Don't Consider The Balance Sheet

Don't forget that the P/E ratio considers market capitalization. Thus, the metric does not reflect cash or debt held by the company. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.

While growth expenditure doesn't always pay off, the point is that it is a good option to have; but one that the P/E ratio ignores.

nLIGHT's Balance Sheet

With net cash of US$142m, nLIGHT has a very strong balance sheet, which may be important for its business. Having said that, at 21% of its market capitalization the cash hoard would contribute towards a higher P/E ratio.

The Verdict On nLIGHT's P/E Ratio

nLIGHT's P/E is 74.7 which suggests the market is more focussed on the future opportunity rather than the current level of earnings. Falling earnings per share is probably keeping traditional value investors away, but the healthy balance sheet means the company retains potential for future growth. If fails to eventuate, the current high P/E could prove to be temporary, as the share price falls.
