Market Valuation
The Market Valuation gauge answers "how expensive is the U.S. stock market today, by historical standards?" We average four long-horizon valuation models that look at price relative to a structural anchor — earnings, GDP, a fitted long-run price trend, or the 10-year Treasury yield. Each input is converted to a percentile against its own history (CAPE uses a 30-year rolling window; the others use full history), then equal-weighted. A high score means today sits in the expensive tail across multiple lenses — single-model bubbles don't lift the gauge on their own.
Historical reading
Reconstructed monthly since 1982-01-04. Each input is ranked using its production calibration: CAPE and Buffett against a trailing 30-year window; Mean Reversion against deviations from a fitted exponential trend; everything else against its full-history distribution. Shaded vertical bands mark NBER recessions.
