How to tell if a stock is expensive: the P/E ratio explained
In short: The P/E = share price ÷ earnings per share. A P/E of 15 means you pay 15 years of current earnings. Compare it with companies in the same sector: a low P/E is not necessarily a bargain, nor a high one necessarily a bad deal.
How to read it
A high P/E means the market expects strong earnings growth. A low P/E can mean an undervalued company… or one in trouble.
Its limits
A loss-making company has no useful P/E. One-off profits in a given year can distort the figure.
On the radar
Each stock page shows the P/E when available, and a daily ranking lists the lowest among large companies.
