### How Do I Calculate A Price To Earnings Ratio?

The formula for P/E is:

Price to Earnings Ratio = Price per Share Ã· Earnings per Share (EPS)

Or for Masimo:

P/E of 45.95 = USD164.03 Ã· USD3.57 (Based on the trailing twelve months to September 2019.)

### Is A High P/E Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each USD1 the company has earned over the last year. That is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

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

The P/E ratio indicates whether the market has higher or lower expectations of a company. You can see in the image below that the average P/E (46.3) for companies in the medical equipment industry is roughly the same as Masimo's P/E.

Masimo's P/E tells us that market participants think its prospects are roughly in line with its industry. The company could surprise by performing better than average, in the future. Further research into factors such as insider buying and selling, could help you form your own view on whether that is likely.

### How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. That's because companies that grow earnings per share quickly will rapidly increase the 'E' in the equation. That means even if the current P/E is high, it will reduce over time if the share price stays flat. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

It's nice to see that Masimo grew EPS by a stonking 34% in the last year. And earnings per share have improved by 27% annually, over the last five years. With that performance, I would expect it to have 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. So it won't reflect the advantage of cash, or disadvantage of debt. 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 Masimo's P/E?

Masimo has net cash of US\$633m. 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 Masimo's P/E Ratio

Masimo trades on a P/E ratio of 45.9, which is above its market average of 18.9. Its net cash position is the cherry on top of its superb EPS growth. So based on this analysis we'd expect Masimo to have a high P/E ratio.
