FAQ
What is AIAE and what does its current level indicate?
AIAE measures the proportion of total household financial assets (equities + fixed income + cash) allocated to equities across the US economy. It currently stands at +51.4%, placing it in the 100.0 historical percentile.
How is AIAE calculated?
AIAE = market value of US equities ÷ (market value of US equities + total liabilities of US borrowers). Debt outstanding stands in for the bonds and cash an investor could hold instead of stocks, so the ratio is the share of the investable pool held as equities. Inputs come from the Federal Reserve's Z.1 Financial Accounts, published quarterly about ten weeks after quarter-end.
