How Do I Calculate A Price To Earnings Ratio?

The formula for price to earnings is:

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

Or for Quidel:

P/E of 34.14 = $56.8 ÷ $1.66 (Based on the trailing twelve months to March 2019.)

Is A High P/E Ratio Good?

The higher the P/E ratio, the higher the price tag of a business, relative to its trailing earnings. 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 Growth Rates Impact P/E Ratios

Earnings growth rates have a big influence on P/E ratios. Earnings growth means that in the future the 'E' will be higher. That means unless the share price increases, the P/E will reduce in a few years. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.

Quidel's 395% EPS improvement over the last year was like bamboo growth after rain; rapid and impressive.

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

The P/E ratio indicates whether the market has higher or lower expectations of a company. If you look at the image below, you can see Quidel has a lower P/E than the average (39) in the medical equipment industry classification.

Quidel's P/E tells us that market participants think it will not fare as well as its peers in the same industry. Since the market seems unimpressed with Quidel, it's quite possible it could surprise on the upside. If you consider the stock interesting, further research is recommended. For example, I often monitor director buying and selling.

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

It's important to note that the P/E ratio considers the market capitalization, not the enterprise value. 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 Quidel's P/E?

Net debt totals just 5.5% of Quidel's market cap. It would probably trade on a higher P/E ratio if it had a lot of cash, but I doubt it is having a big impact.

The Bottom Line On Quidel's P/E Ratio

Quidel trades on a P/E ratio of 34.1, which is above the US market average of 17.8. While the company does use modest debt, its recent earnings growth is superb. So on this analysis a high P/E ratio seems reasonable.
