Applied to the S&P 500 from 2006 to 2026, the model identified three regimes, Extremes, Neutral, and Danger, each with measurably different risk and return characteristics.
The Extremes regime delivers the highest risk-adjusted returns in the dataset. Sharpe 1.34.
Strong directional momentum with compressing volatility. Price near recent highs, credit spreads tight, trend positive. The model reads current conditions as Extremes — the state that captures both melt-up periods and strong recoveries. Historically the highest Sharpe regime, though also the one that immediately precedes many major drawdowns.
The model produces one of three classifications. Each regime has a distinct statistical character — not in average returns, but in the distribution of risk around those returns.
Broad market participation, trending prices, compressing volatility, positive momentum across sectors.
The environment in which equity risk is best compensated. Not a signal to lever up — a signal that the wind is at your back.
No acute stress signals. No strong directional momentum. Markets are moving without a clear behavioral thesis in either direction.
The default state. Markets spend more time here than anywhere else. The absence of a strong signal is itself information.
Credit spreads widening, volatility expanding, momentum deteriorating, macro indicators signaling stress.
Same average return as Neutral. Twice the downside risk. The mean hides the distribution — Danger periods produce the left tail events that define drawdowns.
The mean return in Danger is nearly identical to Neutral. The Sharpe ratio is not. That gap — 0.30 versus 0.55 — is the entire argument for regime awareness.

Past performance of the regime-weighted equity curve shown above is hypothetical and based on walk-forward out-of-sample simulation applied retroactively to historical data. It does not represent actual trading results and has not been verified by any independent third party. Hypothetical performance results have inherent limitations: they are prepared with the benefit of hindsight, do not reflect the impact of material economic and market factors that may have affected actual investment decisions, and do not account for transaction costs, slippage, or taxes. Actual results will differ.
MacroContext regime classifications are produced by a quantitative model that may be incomplete, inaccurate, or subject to revision. The model has failed formal validation criteria on the current run. Full validation results, including pass/fail metrics, are available on the methodology page.
