The PE Ratio Explained
There are many ratios commonly used for the financial analysis of a company, and perhaps the best known is the Price/Earnings (PE) ratio. Ratios are powerful tools because rather than considering some number on its own, they allow us to evaluate a number in the context of another number. Let’s see how this works.
Imagine there are two companies, A and B. Both earned (i.e. made a profit of) $1 million last year - will they have the same value? Suppose A is in an industry that’s dying out and B is in a growth industry – (assuming that both companies have the same number of outstanding shares) which will have the higher stock price? B has the brighter future, the higher likelihood of providing long-term value, so it will have a higher stock price. So given the same earnings, B has the higher price and therefore the higher price/earnings ratio. Thus, the PE ratio is a measure of investors’ optimism about future growth.
Normally we wouldn’t compare companies in different industries. Since different industries have different growth prospects, we would not expect companies across those industries to necessarily have similar PE ratios. But companies within an industry are all subject to the same market forces, so we would generally expect them to have the same growth expectations, and therefore the same ratio of their current price relative to their current profits (earnings). What if we find a company that has a PE ratio that’s higher than the industry average? What might we wonder? This company’s price is higher relative to its earnings than everyone else in the industry (on average) so perhaps that price is too high and this company is overvalued. Or maybe there’s a good reason for investors to be more optimistic. And, of course, if a company has a PE ratio lower than the industry average, then maybe they’re undervalued and a good buy. Or maybe there’s a good reason why their price should be lower. Ratios such as this don’t provide a final decision; they’re just a potential flag to take a further look.
Speaking of taking a further look, next time we’ll take a different look at the PE ratio and how it might be used to determine a company’s value. Better yet, take one of our seminars to learn about many other powerful yet simple analytical ratios!
