AI, Algorithms & Intelligence Systems

The Market Intelligence Stack

RegimeSignal is S&P 500 regime intelligence — calling shifts before the tape confirms them.
Below: the AI infrastructure, algorithms, feeds and processing layers that sit beneath the framework — how the market calls and regime-change alert signals are actually produced.

01

AI Agentic Query

A natural-language agent that sits on top of the live model — ask why the call shifted, what's driving Bull/Bear Velocity, or which factors moved Bear Regime Signal (BRS) overnight, and get a sourced, explainable answer drawn from the same data the signals see.

02

AI-Augmented Signal Systems

Each early-warning signal is paired with an AI scoring layer that weights conditions, surfaces context and flags pre-trigger drift.

03

Machine Learning Components

Gradient-boosted and ensemble learners trained under expanding-window, walk-forward protocols — refit on a regular cadence with strict leakage controls.

04

Geopolitical NLP Monitoring

Continuous classification of policy, conflict and macro-political language into structured event scores feeding the risk layer.

05

Multi-Source Intelligence Feeds

Curated ingest across market data, macro releases, central-bank communications, filings and geopolitical event streams.

06

Market Data Aggregation

Normalized cross-asset feeds — equities, rates, credit, FX, commodities — aligned to a single session-clock for signal evaluation.

07

Liquidity & Macro Processing Pipelines

Dedicated pipelines compute funding, dealer balance-sheet and macro-cycle reads that feed HybridBrain™ exogenous risk.

08

Event Detection Systems

Online detectors flag regime breaks, volatility shocks and correlation dislocations as they form — not after the fact.

09

Real-Time Signal Processing

Low-latency evaluation of the four signals on each new tick of session data, with state transitions logged and timestamped.

10

Adaptive Modeling Systems

Models adapt monthly under a controlled refit cadence — no overnight retraining, no opportunistic curve-fitting.

11

AI Research Workflow

An internal research loop where every candidate feature is tested against the same walk-forward protocol before it can ship.

12

Automated Intelligence Layering

Signal, velocity, liquidity, geopolitical and macro layers are automatically composed into the market calls and regime-change alert signals.

13

Cross-Domain Data Integration

Unified schema lets equity-regime, macro-cycle and exogenous-risk reads be reasoned about together — not in silos.

Deployed Production Signals — 4 Walk-Forward Validated

Algorithms in production

01 · Deployed

Always-on classifier

L1-Regularized Logistic Regression (Lasso) — BRS Layer 1

Sparse, interpretable bear-regime classifier fit on 25 macro/market/positioning factors with monthly refit — walk-forward AUC 0.91 across 304 OOS months, caught 7 of 7 financially-driven bear cycles in OOS (plus 1990 in pre-OOS training history, 8 of 8 overall).

02 · Deployed

Structural corroboration

8-Factor Macro Guardrail Floor — BRS Layer 2

Deterministic FRED-based rules check (GDP, INDPRO, FFR, UMCSENT, CPI, WTI, HY OAS, Fwd P/E) that must independently corroborate before Layer 1 can issue a Bear classification.

03 · Deployed

4-month forward window

XGBoost — Market Break Signal Tier 1 (MBS T1) (5% Pullback Predictor)

Deterministic binary classifier on 34 lagged features targeting any 5% peak-to-trough drawdown within 4 months — precision 83% · recall 76% · AUC 0.88 across 154 OOS months.

04 · Deployed

4-month forward window

XGBoost — Market Break Signal Tier 2 (MBS T2) (10% Correction Predictor)

Identical architecture to T1 with a 10% correction target — precision 84% · recall 82% · AUC 0.92, caught all 4 corrections in OOS (Q4 2018, COVID-era correction, 2022 Bear, 2025 Tariff). Note: COVID is excluded from the BRS bear-regime cycle count as exogenous (handled by the HybridBrain™ ERI overlay); MBS T2's correction detector still flagged the COVID-era −10% drawdown.

05 · Deployed

4-month forward window

XGBoost — Regime Recovery Signal (RRS) (10% Outperform Predictor)

Recovery classifier on 35 momentum/volatility-regime features targeting +10% peak-to-trough surge within 4 months — precision 82% · FPR 1.5% · 154 OOS months.

Design principle

“The model determines the signal. The AI explains it. The AI overlay does not train the model, re-weight factors, or override signals.”
Quant core, untouched · AI as the legibility layer

AI Intelligence Overlay — Six (6) Enhancement Capabilities

What the AI layer adds — without touching the signal

Six AI capabilities sit above the quant core — each interpreting, attributing, or contextualizing the model's output without altering the signal itself. The quant layer generates the regime score. The AI layer makes it legible. None of these capabilities train the model, re-weight factors, or override signals.

AI 1

Anthropic AI Reasoning

LLM-powered interpretation of current model state, calibrated to regime context — produces natural-language explanations of why the composite score is where it is.

AI 2

Real-Time Factor Attribution

Every score change decomposed by driving factor (e.g. Inflation −4.2, Fed Policy −3.8).

AI 3

SHAP Factor Attribution

Shapley values produce mathematically rigorous per-factor contribution values — complements the real-time attribution layer with a principled importance framework.

AI 4

Agentic AI Query

Subscribers query the model in natural language; responses grounded in current factor state, stage transitions, and historical analogs.

AI 5

LLM Weekly Briefing Engine

Claude AI generates institutional-style weekly commentary on regime movement, factor shifts, and stage-transition risk — from admin-curated model state and market context.

AI 6

Live News Intelligence — Perplexity AI

Perplexity-powered real-time geopolitical and macro stress scanner. Suggests factor adjustments — human approval required before any score adjustment applies. No autonomous overrides.

The model determines the signal. The AI explains it. The AI overlay does not train the model, re-weight factors, or override signals.
