Core Idea:
Price-earnings ratios and dividend-price ratios are useful for forecasting future stock price changes.
- The core premise is that valuation ratios will fluctuate within their historical ranges in the future; when a ratio is at an extreme level, it will mean revert, and either the numerator or the denominator are forecastable.
- Dividend-price ratios are a poor predictor of future dividend growth (R-square = 0.25%); however, dividend-price ratios are a much stronger predictor of future real price changes (R-square = 63%).
- Price-smoothed-earnings ratios also have special significance.
Alpha Highlight:
Faber (2012) applied this valuation metric across more than 30 foreign markets and finds it both practical and useful. Below are two charts from Faber (2012).
