### How Do You Calculate NanoEnTek’s P/E Ratio?

The formula for P/E is:

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

Or for NanoEnTek:

P/E of 34.21 = ₩5700.000 ÷ ₩166.601 (Based on the year to September 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 implies that investors pay a higher price for the earning power of the business. 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.

### Does NanoEnTek 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. The image below shows that NanoEnTek has a P/E ratio that is roughly in line with the life sciences industry average (34.0).

Its P/E ratio suggests that NanoEnTek 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. Checking factors such as director buying and selling. could help you form your own view on if that will happen.

### 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. If earnings are growing quickly, then the ‘E’ in the equation will increase faster than it would otherwise. 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.

NanoEnTek’s earnings made like a rocket, taking off 451% last year.

### 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. In other words, it does not consider any debt or cash that the company may have on the balance sheet. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

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.

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