[ How MSD Plugs Into Your Book ]
Market State Detector (MSD) classifies each U.S. trading day into one of five regime states (Calm, Turning, Stress, Volatility Spike, Systemic Stress), delivered before the open. The differentiating input is exogenous environmental data — signals not in anyone else's stack and orthogonal to the regime models in the rest of yours.
The classifier also incorporates SPX and VIX as inputs alongside the environmental signals. Walk-forward validated 2012–2024. This brief covers how five strategy archetypes use the daily state as a position-sizing input.
Your strategy doesn't change.
Your sizing does.

Every archetype rule in this brief references these five names. Each state has its own classification logic, precision, and historical frequency. There is no mapping between any one strategy and any one state — every archetype uses all five.
Default state. Markets quiet, VIX median 14. Hedges decay; vol carry earns.
Regime inflection. 95% precision, 2-day median lead before stress shows in price.
Selective heads-up. ~5 days/year (2%), 60% precision. A confirmation tier — pair with other evidence before sizing.
Rapid vol dislocation. 92.86% precision (13 of 14). VIX already elevated at firing.
Crisis classifier. 100% precision (9 of 9), 2012–2024. Includes COVID and Aug 2024.
Distribution: 2012–2024 walk-forward. Precision figures from MSD canonical manifests.
Each line is one archetype: the claim, the historical effect, and the strategies it covers. Pick the one that fits what your desk runs and flip to its page. Every archetype uses all five states from the previous page.
Programs that buy protection pay premium every day whether or not the protection is doing work. MSD tells you which days are Calm, the regime where that premium has historically decayed without paying for itself. Size the protection book down on Calm days; ramp it back up the moment MSD flags any non-Calm state. Same protection during stress. Less premium spent during quiet.
Trend strategies make money when regimes hold and lose money when regimes break. The pain concentrates in a small number of regime-change days. MSD flags those days as Turning, Stress, Vol Spike, or Systemic Stress before the break shows up in price. Hold full size during Calm (where trends actually work). Scale down or go flat the moment MSD flags a regime change. Same trend signal. Same execution. Smaller worst-case path.
Selling vol earns carry when markets are quiet and breaks expensively when the regime shifts. Turning flags the regime shift before VIX moves materially. Close the short-vol book the morning Turning fires; re-enter only on the next Calm. The historical re-entry signal is consistent: 83% of crisis episodes ended with a Turning classification within 10 trading days, which is when carry conditions historically returned.
Long-volatility books bleed premium during Calm and earn convexity during crises. The same annual budget gets a much better payoff if you spend less during Calm and more during MSD-flagged crisis states. Systemic Stress flagged 9 of 9 events in the canonical backtest, so the scaled-up notional has historically landed where the convexity actually lives. Same dollar budget. Deeper protection where it matters.
Different factors win in different regimes. Momentum crashes hardest during regime breaks; quality and low-vol earn during stress; value rotates with macro. MSD provides an exogenous regime input to drive factor tilts, instead of inferring regime from the same prices the factors already use (which is circular). The framework here is a methodology spec; the historical backtest is reproducible on your firm’s own factor return series.
The regime signal scales the trades you already make. Vol-targeting, signal selection, instrument choice, and risk framework all stay exactly as they are today.
Delivered before the U.S. open via API or webhook. No intraday updates. Your risk system reads it once, looks up the sizing rule, applies it before you trade.
