How Do You Calculate A P/E Ratio?

The formula for P/E is:

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

Or for Integral Diagnostics:

P/E of 30.54 = AUD4.08 ÷ AUD0.13 (Based on the trailing twelve months to June 2019.)

Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that investors are paying a higher price for each AUD1 of company 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 Does Integral Diagnostics's P/E Ratio Compare To Its Peers?

The P/E ratio indicates whether the market has higher or lower expectations of a company. As you can see below, Integral Diagnostics has a higher P/E than the average company (19.6) in the healthcare industry.

ASX:IDX Price Estimation Relative to Market, January 30th 2020

Integral Diagnostics's P/E tells us that market participants think the company will perform better than its industry peers, going forward. 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

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. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Integral Diagnostics increased earnings per share by a whopping 29% last year. And it has bolstered its earnings per share by 23% per year 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

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. Thus, the metric does not reflect cash or debt held by the company. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its cash).

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).

So What Does Integral Diagnostics's Balance Sheet Tell Us?

Net debt totals 13% of Integral Diagnostics's market cap. That's enough debt to impact the P/E ratio a little; so keep it in mind if you're comparing it to companies without debt.

The Verdict On Integral Diagnostics's P/E Ratio

Integral Diagnostics has a P/E of 30.5. That's higher than the average in its market, which is 18.7. While the company does use modest debt, its recent earnings growth is very good. So on this analysis it seems reasonable that its P/E ratio is above average.
