This stock market bubble score measures how closely today resembles historically overheated US equity markets. It does not predict when prices will turn—or whether they must.
Each indicator is normalized from 0–100 against transparent thresholds, then weighted toward fundamentals: valuation 45%, leverage 25%, positioning 10%, credit 12%, sentiment 8%.
A temperature check, not a crystal ball.
A bubble is not simply a market at an all-time high. It is a market where prices, leverage and confidence detach from the economic fundamentals beneath them. The composite score shows how strongly those conditions align today.
The Shiller CAPE and market-value-to-GDP ratio measure valuation. FINRA margin debt measures leverage. Household equity allocation captures positioning, while credit spreads and the VIX measure risk appetite.
