Reading these multiples
The P/E divides the share price by earnings per share over the last twelve months; the forward P/E divides it by the earnings analysts expect over the next twelve. Price to sales compares the company's market value with its revenue over the last twelve months. A multiple reads differently from one industry to the next, so the peer group above is the fairer comparison.
