How Do I Calculate A Price To Earnings Ratio?

The formula for price to earnings is:

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

Or for Power Integrations:

P/E of 14.56 = $96.220 ÷ $6.610 (Based on the year to December 2019.)

(Note: the above calculation results may not be precise due to rounding.)

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.

Does Power Integrations Have A Relatively High Or Low P/E For Its Industry?

Power Integrations's P/E tells us that market participants think it will not fare as well as its peers in the same industry. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. It is arguably worth checking if insiders are buying shares, because that might imply they believe the stock is undervalued.

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. When earnings grow, the 'E' increases, over time. 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.

Power Integrations's 178% EPS improvement over the last year was like bamboo growth after rain; rapid and impressive. The cherry on top is that the five year growth rate was an impressive 27% per year. With that kind of growth rate we would generally expect a high P/E ratio.

Remember: P/E Ratios Don't Consider The Balance Sheet

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. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

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).

How Does Power Integrations's Debt Impact Its P/E Ratio?

Power Integrations has net cash of US$411m. This is fairly high at 14% of its market capitalization. That might mean balance sheet strength is important to the business, but should also help push the P/E a bit higher than it would otherwise be.

The Bottom Line On Power Integrations's P/E Ratio

Power Integrations has a P/E of 14.6. That's around the same as the average in the US market, which is 13.7. Its net cash position is the cherry on top of its superb EPS growth. So based on this analysis we'd expect Power Integrations to have a higher P/E ratio.
