This article is written for those who want to get better at using price to earnings ratios (P/E ratios). We'll look at Nanometrics Incorporated's (NASDAQ:NANO) P/E ratio and reflect on what it tells us about the company's share price. Looking at earnings over the last twelve months, Nanometrics has a P/E ratio of 13.11. That means that at current prices, buyers pay $13.11 for every $1 in trailing yearly profits.
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 Nanometrics:
P/E of 13.11 = $31.34 ÷ $2.39 (Based on the trailing twelve months to December 2018.)
Is A High Price-to-Earnings Ratio Good?
A higher P/E ratio means that buyers have to pay a higher price for each $1 the company has earned over the last year. That isn't a good or a bad thing on its own, but a high P/E means that buyers have a higher opinion of the business's prospects, relative to stocks with a lower P/E.
How Growth Rates Impact P/E Ratios
P/E ratios primarily reflect market expectations around earnings growth rates. 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.
Nanometrics's earnings made like a rocket, taking off 99% last year. And earnings per share have improved by 171% annually, over the last three years. So you might say it really deserves to have an above-average P/E ratio.
Does Nanometrics Have A Relatively High Or Low P/E For Its Industry?
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 Nanometrics has a lower P/E than the average (19.8) in the semiconductor industry classification.
This suggests that market participants think Nanometrics will underperform other companies in its industry. Many investors like to buy stocks when the market is pessimistic about their prospects. If you consider the stock interesting, further research is recommended. For example, I often monitor director buying and selling.
Remember: P/E Ratios Don't Consider The Balance Sheet
One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. That means it doesn't take debt or cash into account. 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).
So What Does Nanometrics's Balance Sheet Tell Us?
Nanometrics has net cash of US$152m. This is fairly high at 20% 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 Nanometrics's P/E Ratio
Nanometrics's P/E is 13.1 which is below average (18.1) in the US market. It grew its EPS nicely over the last year, and the healthy balance sheet implies there is more potential for growth. The relatively low P/E ratio implies the market is pessimistic.
When the market is wrong about a stock, it gives savvy investors an opportunity. If the reality for a company is not as bad as the P/E ratio indicates, then the share price should increase as the market realizes this.
