### 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 NewMarket:

P/E of 18.99 = USD452.52 ÷ USD23.83 (Based on the year to September 2019.)

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

A higher P/E ratio means that investors are paying a higher price for each USD1 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.

### Does NewMarket Have A Relatively High Or Low P/E For Its Industry?

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 (20.4) for companies in the chemicals industry is roughly the same as NewMarket’s P/E.

Its P/E ratio suggests that NewMarket shareholders think that in the future it will perform about the same as other companies in its industry classification. The company could surprise by performing better than average, in the future. I would further inform my view by checking insider buying and selling., among other things.

### 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. A lower P/E should indicate the stock is cheap relative to others — and that may attract buyers.

NewMarket’s 58% EPS improvement over the last year was like bamboo growth after rain; rapid and impressive. Having said that, if we look back three years, EPS growth has averaged a comparatively less impressive 4.0%.

### 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. That means it doesn’t take debt or cash into account. 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).

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.

### How Does NewMarket’s Debt Impact Its P/E Ratio?

Net debt totals 11% of NewMarket’s market cap. This could bring some additional risk, and reduce the number of investment options for management; worth remembering if you compare its P/E to businesses without debt.

### The Verdict On NewMarket’s P/E Ratio

NewMarket has a P/E of 19.0. That’s around the same as the average in the US market, which is 18.6. With only modest debt levels, and strong earnings growth, the market seems to doubt that the growth can be maintained.
