This article is written for those who want to get better at using price to earnings ratios (P/E ratios). We'll show how you can use Thales S.A.'s (EPA:HO) P/E ratio to inform your assessment of the investment opportunity. What is Thales's P/E ratio? Well, based on the last twelve months it is 18.50. That is equivalent to an earnings yield of about 5.4%.
How Do You Calculate Thales's P/E Ratio?
The formula for P/E is:
Price to Earnings Ratio = Share Price ÷ Earnings per Share (EPS)
Or for Thales:
P/E of 18.50 = €94.12 ÷ €5.09 (Based on the trailing twelve months to June 2019.)
Is A High P/E Ratio Good?
A higher P/E ratio means that investors are paying a higher price for each €1 of company earnings. 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 Does Thales's P/E Ratio Compare To Its Peers?
We can get an indication of market expectations by looking at the P/E ratio. We can see in the image below that the average P/E (22.3) for companies in the aerospace & defense industry is higher than Thales's P/E.
Thales's P/E tells us that market participants think it will not fare as well as its peers in the same industry. Many investors like to buy stocks when the market is pessimistic about their prospects. 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
P/E ratios primarily reflect market expectations around earnings growth rates. That's because companies that grow earnings per share quickly will rapidly increase the 'E' in the equation. That means even if the current P/E is high, it will reduce over time if the share price stays flat. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.
Notably, Thales grew EPS by a whopping 29% in the last year. And its annual EPS growth rate over 5 years is 4.8%. With that performance, I would expect it to have an above average P/E ratio.
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. So it won't reflect the advantage of cash, or disadvantage of debt. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.
Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.
How Does Thales's Debt Impact Its P/E Ratio?
Net debt totals 14% of Thales'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 Thales's P/E Ratio
Thales trades on a P/E ratio of 18.5, which is fairly close to the FR market average of 18.2. With only modest debt levels, and strong earnings growth, the market seems to doubt that the growth can be maintained. Given analysts are expecting further growth, one might have expected a higher P/E ratio. That may be worth further research.
Investors have an opportunity when market expectations about a stock are wrong. People often underestimate remarkable growth -- so investors can make money when fast growth is not fully appreciated. So this free visualization of the analyst consensus on future earnings could help you make the right decision about whether to buy, sell, or hold.
