Market Strain Gauge

Individual stocks have a scorecard. This is the one for the whole market — two long-run valuation measures, each shown against its own history, so you can see how today compares with 1999, 2007 and every month in between.

The label is a fixed rule, not a forecast: under 0.9× reads Below normal, 1.25× Normal, 1.75× Elevated, 2.25× High, and above that Extreme. Stretched valuations say nothing about when anything happens — markets have stayed expensive for years. Informational only; not investment advice.

Reading the warning signs

  • The valuation gap. CAPE sits at 40.58 against a long-run average of 17.8 across 1,749 months of history.
  • The dot-com ceiling. CAPE has been higher in only 20 of 1,749 months on record — every one of them in 1999 and 2000 and 2026, peaking at 44.2 in Dec 1999.
  • The Buffett Indicator. Total US corporate equity is worth 218% of GDP, against a post-war average of 86%. Its record is 229% in Oct 2025.

The Buffett Indicator here uses the Federal Reserve's own Z.1 corporate-equities level over GDP — the original definition. Versions built on the Wilshire 5000 (as quoted by some sites) read materially higher; Wilshire's series is no longer published on FRED. Sources: Shiller CAPE (Robert J. Shiller, Yale), Corporate equities, Federal Reserve Z.1 via FRED, US GDP via FRED.
