See the turn before Wall Street does.
Wall Street reacts after the event — after the drawdown,
the panic, and the rebound.
RegimeSignal™ was engineered to predict the market's full cycle. Its multi-signal framework is designed to flag bear regimes, correction landmines, the panic, and the rebound — before consensus prices them.
With approximately 84% validated precision across the entire S&P 500 market cycle, RegimeSignal™ was built to recognize regime shifts before they become consensus.
Not hindsight. Not lagging indicators. Forward-looking market regime intelligence.

What it's for
A full-cycle early market warning system.
One purpose, four jobs. Below is what RegimeSignal™ is built to do — the signals that power each job come right after.
Anticipate
Read forming bear regimes well before they reach consensus.
Position
Frame pullbacks, drawdowns, and weakening internals while they're still actionable.
Re-engage
Confirm bull recoveries with conviction — not on the headline bounce.
Filter
Separate routine noise from regime-level structural change.
The signals
Four validated models. One complete-cycle foresight engine for the S&P 500.
Each signal is independently constructed and walk-forward validated. Together with Bull Velocity and Bear Velocity, they cover the full S&P 500 cycle — from pullback warning to bear regime to confirmed recovery.
BRS
Bear Regime Signal™
86%¹
Precision when fires
Sees bear markets coming as they form — not after the damage is done. Fires Bear Alerts as the early warning layer for −20% regime risk.
Bear Alert · regime classifier
MBS T1
Market Break Signal — Tier 1
83%²
Precision when fires
Calls −5% pullbacks ahead of the move and triggers the Neutral state — a tactical heads-up before the dip.
Pullback · −5% · Neutral state trigger
MBS T2
Market Break Signal — Tier 2
84%³
Precision when fires
Calls −10% corrections four months ahead — the kind that actually hurt — and hands off to BRS when conditions deepen toward bear.
Correction · −10% · Underperform trigger
RRS
Regime Recovery Signal™
82%⁴
Precision when fires
Calls bull-market recovery (+10%) ahead. Stays silent during fake-out rallies, speaks up when the bull is real — the high-conviction “safe to re-engage” call.
Recovery · +10% confirmation
Directional gauges only5 — not state triggers; excluded from the 4-signal aggregate due to statistical thinness, disclosed honestly. Useful as supporting context; their contribution to the composite score diminishes as signals decay over time.
Bull Velocity Rating
BWS engineWithin-bull weakening score — watches floorboards creak before the house comes down. 87% within-bull precision across 47 OOS months but AUC 0.67 with N=14 negatives — confirmatory only, not a fire signal.
Bear Velocity Rating
BES engineWithin-bear directional gauge tracking bear-to-recovery transitions. Often precedes RRS by weeks during recovery turns. 21 LOO-CV samples (COVID-dominated) — not walk-forward validated; confirmation only, never a fire signal.
Bull Health Tracker
BHT · descriptive0–100 descriptive companion to Bull Velocity, calibrated against 33 years of bull history (310 clean bull months 1993–2026). Second lens on the same evidence — 60 ≈ historical bull low, 90 ≈ historical bull peak.
Pullback Resolution Gauge
PRG · Neutral companionWithin-Neutral directional gauge — measures which way a Neutral state is resolving. Composite of MBS T1, MBS T2, BRS distance-to-bear, and daily news flow. Components walk-forward validated; composite weighting is not. Confirmatory only.
Recovery Durability Gauge
RDG · Recovery companionWithin-Recovery directional gauge — distinguishes durable returns from bear-market rallies. Composite of RRS, Bear Velocity slope, BRS exit, price vs. 200-day MA, and credit spreads. Components walk-forward validated; composite weighting is not.
Validated with Qualifications
An independent PhD reviewer validated all four RegimeSignal™ market-prediction signals, confirming that the published historical results could be reproduced exactly from the locked files and that the testing methodology was sound. The review identified no look-ahead bias or data leakage, and concluded that the signals were "Validated with Qualifications," with all limitations fully disclosed.
Methodology
Disciplined. Validated. Continuously adapted.
No black boxes, no narrative overlays — just a transparent, evidence-driven framework refit on a fixed cadence.
Walk-forward validation
Every signal is constructed and tested under walk-forward protocols designed to mirror real-time decision-making — not curve-fit hindsight.
Expanding-window refits
Classifier models are refit on a regular cadence using expanding windows, so the framework can adapt as markets evolve without discarding cycle history.
AI-augmented, not AI-driven
Machine learning sharpens signal construction and gauge calibration. The methodology, regime definitions, and decision logic remain transparent and auditable.
What it's for
Built for forward-looking risk decisions.
Detect bear formations
Identify the conditions under which S&P 500 bull markets historically transition into bear regimes — before they price.
Anticipate drawdowns
Surface weakening internals during active bull markets, when corrections are most often ignored by consensus.
Confirm recoveries
Distinguish durable bull market recoveries from bear market rallies using signal-based confirmation, not narrative.
Forward-looking signal intelligence
8 for 8 — every financially-driven S&P 500 bear regime caught ahead of time (7 of 7 in walk-forward OOS + 1990 in pre-OOS training history).

COVID March 2020 excluded as exogenous (handled by the HybridBrain™ ERI overlay). Validation summary across the locked model suite.
Precision = share of fires followed by the predicted event within the model's forward window. OOS = out-of-sample (walk-forward); LOO-CV = leave-one-out cross-validation. Past market signal record does not guarantee future results.
5 Directional engines (not formal signals): BWS — 47 OOS months, AUC 0.67, threshold ≥ 0.70, within-BULL only — powers Bull Velocity. BES — 21 LOO-CV BEAR months, threshold ≥ 0.55, within-BEAR only — powers Bear Velocity. BHT — descriptive 0–100 companion to Bull Velocity, calibrated against 310 clean bull months (1993–2026); inherits the BWS validation profile. PRG — within-NEUTRAL composite of MBS T1, MBS T2, BRS distance-to-bear, and news flow; components walk-forward validated (footnotes 1–3), composite weighting is not. RDG — within-RECOVERY composite of RRS, BES slope, BRS exit, SPX/200dma, HY OAS; components from validated signals (footnotes 1, 4) plus BES, composite weighting is not. ⚠ All five excluded from the formal 4-signal count — disclosed honestly.
