Definition
Trailing Price-to-Earnings (Trailing P/E): A relative valuation metric used to determine a company’s current share price in relation to its earnings over the past 12 months. It is calculated by taking the company’s current stock price and dividing it by the trailing earnings per share (EPS) of the preceding year.
Trailing P/E vs Forward P/E
| Feature | Trailing P/E | Forward P/E |
|---|---|---|
| Basis | Past earnings (last 12 months) | Projected future earnings |
| Calculation | Current Stock Price / Last 12 Months EPS | Current Stock Price / Projected EPS |
| Use case | Historical perspective | Forward-looking potential |
| Accuracy | Reflects past performance | Based on estimates and predictions |
Examples
-
If a company has a stock price of $50 and its earnings per share over the last 12 months were $5, then: \[ \text{Trailing P/E} = \frac{50}{5} = 10 \] The trailing P/E of 10 indicates that investors are willing to pay $10 for every $1 of earnings from the past year.
-
Conversely, if a company’s stock price is $30 and analysts expect its future EPS to be $6, the forward P/E is: \[ \text{Forward P/E} = \frac{30}{6} = 5 \] Interestingly, this implies the future is worth much more than the past—like a superhero story where the hero always saves the day, but we never see how they train!
