What the PE ratio tells you
Share price divided by earnings per share over the last twelve months. It is the price tag on a dollar of profit: 20× means you pay $20 for $1 of yearly earnings.
Blank while earnings are negative. A very low PE can mean the market expects profits to fall, so read it with growth and the company's own history.
