What is forward P/E and how is it calculated
Forward P/E divides the share price by the earnings per share analysts expect over the next 12 months, not by the profit already reported. It shows how expensive the stock is relative to tomorrow's profit, not yesterday's.
Forward P/E formula
- Estimated EPS
- The average of analysts' estimates for earnings per share over the next 12 months.
Worked example
A stock trades at $120. Profit over the last year was $8 per share, and analysts expect $10 next year.
If profit grows as expected, the stock is cheaper than the regular P/E suggests.
How to read forward P/E
When forward P/E is well below the regular P/E, analysts expect strong profit growth. When it is above, they expect profit to fall.
When forward P/E can fool you
Estimates are wrong: analysts tend to be too optimistic, especially for fast growers. Few analysts: for small companies, a single estimate changes everything. Adjusted figures: estimates often use "adjusted" profit, higher than the officially reported one.
