### 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 National Instruments:

P/E of 32.40 = \$39.880 ÷ \$1.231 (Based on the trailing twelve months to December 2019.)

(Note: the above calculation results may not be precise due to rounding.)

### Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each \$1 the company has earned over the last year. 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 National Instruments’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. You can see in the image below that the average P/E (17.5) for companies in the electronic industry is lower than National Instruments’s P/E.

That means that the market expects National Instruments will outperform other companies in its industry. The market is optimistic about the future, but that doesn’t guarantee future growth. So investors should delve deeper. I like to check if company insiders have been buying or selling.

### How Growth Rates Impact P/E Ratios

Probably the most important factor in determining what P/E a company trades on is the earnings growth. That’s because companies that grow earnings per share quickly will rapidly increase the ‘E’ in the equation. That means unless the share price increases, the P/E will reduce in a few years. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

National Instruments’s earnings per share grew by -4.8% in the last twelve months. And its annual EPS growth rate over 5 years is 4.4%.

### A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

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.

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.

### National Instruments’s Balance Sheet

Since National Instruments holds net cash of US\$433m, it can spend on growth, justifying a higher P/E ratio than otherwise.

### The Bottom Line On National Instruments’s P/E Ratio

National Instruments trades on a P/E ratio of 32.4, which is above its market average of 16.2. EPS was up modestly better over the last twelve months. And the net cash position provides the company with multiple options. The high P/E suggests the market thinks further growth will come.
