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 St Barbara:
P/E of 7.94 = A$3.12 ÷ A$0.39 (Based on the year to December 2018.)
Is A High P/E Ratio Good?
A higher P/E ratio means that investors are paying a higher price for each A$1 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 Growth Rates Impact P/E Ratios
Earnings growth rates have a big influence on P/E ratios. When earnings grow, the 'E' increases, over time. And in that case, the P/E ratio itself will drop rather quickly. And as that P/E ratio drops, the company will look cheap, unless its share price increases.
St Barbara saw earnings per share improve by -9.4% last year. And its annual EPS growth rate over 3 years is 22%.
How Does St Barbara's P/E Ratio Compare To Its Peers?
One good way to get a quick read on what market participants expect of a company is to look at its P/E ratio. We can see in the image below that the average P/E (12.6) for companies in the metals and mining industry is higher than St Barbara's P/E.
St Barbara's P/E tells us that market participants think it will not fare as well as its peers in the same industry. Since the market seems unimpressed with St Barbara, it's quite possible it could surprise on the upside. You should delve deeper. I like to check if company insiders have been buying or selling.
A Limitation: P/E Ratios Ignore Debt and Cash In The Bank
The 'Price' in P/E reflects the market capitalization of the company. So it won't reflect the advantage of cash, or disadvantage of debt. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.
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 St Barbara's Debt Impact Its P/E Ratio?
With net cash of AU$357m, St Barbara has a very strong balance sheet, which may be important for its business. Having said that, at 21% of its market capitalization the cash hoard would contribute towards a higher P/E ratio.
