Price to Earnings (P/E) is a financial metric which shows the ratio of a firm's current share price to its earnings per share. This is an extremely common multiple used to evaluate whether a company is under or overpriced. Usually the higher the P/E ratio, the more overvalued the firm is.
The calculation of P/E is:
- Market Value Per Share / Earnings Per Share
For example, if a share is currently trading at $50 and EPS are $2 per share, the P/E ratio is 25 ($50 / $2).
The P/E of different firms cannot really be compared unless they are in the same sector as the typically P/E values will vary between sectors. Technology firms for example usually have high P/E ratios.
