How this regime is defined

Inflation environment reads Moderate in the daily regime record.

Method and limits

Descriptive statistics over the published regime record — not a backtest, a forecast or advice. Each regime day is credited with the NEXT session's return, so a regime never earns the move that revealed it. Returns are ETF price returns (dividends excluded), annualised as 252 × the mean session return; volatility likewise. Sector funds start in December 1998 (Real Estate in 2015, Communication Services in 2018); the regime record starts in 1980. Labels are the engine's as currently published and are recomputed when its method improves. A figure with fewer than 60 sessions is not shown.
