Market State Detector — Complete States Reference

The Market State Detector classifies market conditions into five distinct states. Each state has specific activation logic, typical market characteristics, and historical performance metrics (2012-2024).

Jump to State

Systemic Stress State

Precision: 100.00%Activations: 9False Positives: 0

Ultra-selective classification for crisis-grade market dislocations.

Activation Logic

Multi-factor thresholds breach simultaneously
Median lead time: 0 business days (same-day activation)
Frequency: 0.69 per year (ultra-rare)
9 activations across 13 years (2012-2024)

Typical Market Context

Historically observed during VIX ≥35 conditions
SPX declines ≥3% in 5 days or ≥6% in 10 days
Sustained extreme volatility environments
Median VIX during episodes: 24.59 (vs 15.8 baseline)

Institutional Use

Crisis playbook activation signal
Pre-market awareness for risk committees
Scenario planning for extreme conditions
Historical context for hedge timing and position reviews

Portfolio Context

Historically classified 9 crisis episodes with 100% precision
Used as early-stage awareness tool, not predictive signal
Research context for scenario planning
Classification delivered pre-market (~07:30 ET)

Important Considerations

Rare by design: 9 activations in 13 years
Median same-day lead requires quick response
One correct classification may justify years of monitoring
Not investment advice; research use only

Stress State (Advisory)

Precision: 60.00%Activations: 15False Positives: 6

Advisory-tier elevated stress context for heightened market vigilance.

Activation Logic

Advisory tier: elevated conditions detected
60% precision: hit conditions materialize in majority of cases
Episodes average 5 trading days
1.15 activations per year; 15 episodes (2012-2024)

Typical Market Context

Historically observed during VIX ≥30 conditions
SPX declines approaching -3% to -5% range
Elevated stress building before critical thresholds
Median VIX during episodes: 23.39 (vs 15.8 baseline)

Institutional Use

Early awareness for risk committees
Intermediate alert between normal and critical
Scenario planning before full escalation
Historically followed by hit conditions 60% of the time

Portfolio Context

Historically classified 15 elevated stress periods
Used for pre-positioning and attention calibration
Intermediate-severity classification with measurable follow-through
Research context; not investment advice

Important Considerations

60% precision = 40% resolved without hitting thresholds
Balance between early warning and false positives
Best used alongside other state classifications
Not predictive; informational research only

Volatility Spike State

Precision: 92.86%Activations: 14False Positives: 1

Short-duration volatility expansion classification for rapid market shifts.

Activation Logic

Captures sharp volatility expansions
Median lead time: 0 business days
Frequency: 1.08 activations per year
14 activations across 13 years (2012-2024)

Typical Market Context

Historically observed during VIX ≥30 conditions
Sudden market volatility increases
Short-duration events (median 3 business days)
Median VIX during episodes: 25.89 (vs 15.8 baseline)

Institutional Use

Tactical hedging signal for short-term volatility
Portfolio rebalancing awareness
Risk committee notification
Historically reduces false positives vs single-threshold alerts

Portfolio Context

Historically classified 14 volatility spikes with 93% precision
Used for tactical positioning and hedge timing
Rules-based and reproducible classification system
Research context; not trading signals

Important Considerations

Short-duration: requires quick response
Not all volatility spikes persist beyond median 3 trading-day window
Best used in combination with other risk signals
Not investment advice; informational research only

Turning State

Precision: 95.08%Activations: 61False Positives: 3

Regime transition / inflection classification for identifying market pivots.

Activation Logic

Multi-day lead before market dislocation
Median lead time: 2 business days
Frequency: 4.69 activations per year
61 activations across 13 years (2012-2024)

Typical Market Context

Historically observed before regime transitions
Inflection points preceding volatility increases
Pre-conditions for drawdowns or volatility spikes
Median VIX during episodes: 25.23 (vs 15.8 baseline)

Institutional Use

Early warning for portfolio positioning
Hedge activation before spreads widen
Transition alert: stable to stressed conditions
Historically leads VIX increases by median 2 trading days

Portfolio Context

Historically classified 61 inflection points with 95% precision
Used for pre-positioning before market shifts
Most frequent state; balance sensitivity with frequency
Research context for scenario planning

Important Considerations

More frequent (4.69/year) requires clear action plan
Some inflections resolve without major moves
2 trading-day lead provides narrow window for execution
Not predictive; informational research only

Calm State

Precision: 70.70% of daysActivations: —False Positives: —

Baseline / non-alert state derived from the suite, indicating stable market conditions.

Activation Logic

Default classification when no stress states are active
Represents ~92% of market conditions (2012-2024)
Not an alert; represents normal market context
Meta-state: absence of other classifications

Typical Market Context

Normal volatility environment
No crisis or elevated stress conditions
Standard market conditions
Baseline state for comparison and calibration

Institutional Use

Baseline reference for comparison
Context for understanding when other states activate
Risk calibration and normalization
Not actionable; informational baseline only

Portfolio Context

Represents typical market conditions
Provides baseline for state transitions
Not a signal or classification; default state
No action required; context only

Important Considerations

Not a signal; just absence of stress classifications
Do not confuse with "low risk" prediction
Market can shift rapidly from Calm to Stress states
Not investment advice; informational baseline only

Crisis Cycle Behavior

Historically, MSD has classified complete crisis cycles — from early warning signals to recovery transitions. These patterns observed during 2012-2024:

Crisis Duration

Systemic Stress episodes averaged 7 trading days. Volatility Spike episodes averaged 3 trading days. Crisis states were historically intense but short-lived.

Recovery Transitions

Turning classifications historically followed crisis episodes, with median 2 trading-day lead before market dislocations.

Calm Persistence

Calm state represented approximately 92% of days (2012-2024), historically remaining stable for extended periods.

Advisory Precision

Stress Advisory achieved 60% precision. When classified, elevated conditions (VIX ≥30 or SPX drops) historically followed in the majority of cases.

How States Are Determined

Market State Detector classifications are produced by a rules-based engine using versioned rule definitions. Each state is defined by a specific rule (with a version and integrity hash) and evaluated on a trading-day schedule using market inputs and environmental stress indicators.

Rule Definition

Each state rule defines trigger conditions, episode windowing (window/cooldown), and scoring horizon.

Winner-State Resolution

If multiple rules are active on a day, the published daily state uses a fixed priority order: Systemic Stress > Volatility Spike > Stress (Advisory) > Turning; otherwise Calm.

Calm State

Calm is a meta-state that is active only when all other stress/transition states are inactive.

Auditability

Performance metrics are published from manifests (2012–2024). Rule IDs, versions, and validation files are traceable for reproducibility.

For public safety and IP protection, this page intentionally describes the system at a high level. Full methodology and validation conditions are documented at mindforge.tech/validation-and-methods.
