Market Regime Classification: A Diagnostic Framework for Position Traders

What Is Market Regime Classification?

Market regime classification is a systematic framework that assigns every financial asset to one of six structural states — from confirmed uptrend to structural breakdown — based on price structure, volume behavior, institutional positioning, and macro context. Unlike binary "buy or sell" indicators, regime classification provides a continuous diagnostic: it tells the observer what phase the market is in, not what it will do next.

The concept is borrowed from medical triage. In an emergency room, patients are not labeled "healthy or sick." They are classified by urgency: stable, needs monitoring, elevated risk, critical. The classification determines the type of attention required, not the outcome. Market regime classification applies the same logic to financial assets — each of the six states maps to a distinct posture a position trader might adopt.

MarketTriage implements this framework across 212 assets — equities (S&P 100), ETFs (SPY, QQQ, 11 sector SPDRs), indices, commodities, and cryptocurrencies. Every asset is re-evaluated in each pipeline run using 30+ signals, and the regime is stored alongside a conviction score that quantifies the weight of evidence behind the classification.

Think of regime classification as an X-ray of market structure. It does not predict whether a patient will recover — it shows the current structural condition so that the right level of attention is applied. A CRITICAL regime is not a "sell signal." It is a diagnostic observation that multiple exhaustion indicators are present simultaneously at a structural high.

Why 6 States Instead of Bullish or Bearish?

Most market regime models use two to four states — typically bull, bear, volatile, and range-bound. These frameworks, often built on Hidden Markov Models or simple moving average crossovers, capture the broad strokes of a market cycle. But they miss the transition zones — and the transition zones are where most capital is made or lost.

Consider the medical analogy: a hospital that classifies patients as only "healthy" or "sick" misses the patients who are deteriorating and those who are recovering — the two groups that need the most attention. MarketTriage's ELEVATED regime captures the deteriorating phase (one crack has appeared at highs, but distribution is not yet confirmed). OBSERVATION captures the recovery phase (accumulation signals are present at lows, but a reversal is not yet confirmed). These are distinct structural states that a binary bull/bear model collapses into noise.

The six-state model also enables per-asset classification. Traditional regime models typically describe "the market" as a whole — the S&P 500 is in a bull regime, or the Nasdaq is in a bear regime. MarketTriage classifies each of its 212 assets independently. During any given week, some equities may be in CLEARANCE while others are in CODE BLUE. The regime is a property of the individual asset, not the market.

A 2-state model tells a trader whether the market is rising or falling. A 6-state model tells a position trader whether an asset is trending (CLEARANCE), showing early stress (ELEVATED), confirming distribution (CRITICAL), breaking down structurally (CODE BLUE), accumulating at a base (OBSERVATION), or showing no edge at all (STABLE). The distinction determines whether the appropriate posture is attention, patience, or avoidance.

The 6 Market Regimes

MarketTriage classifies every asset into exactly one of six regimes. The classification is priority-ordered — the system checks for CRITICAL first, then OBSERVATION, then CODE BLUE, and so on. The first match wins. This means an asset at 52-week highs with three exhaustion signals will be classified as CRITICAL even if it also has bullish trend confirmation — exhaustion at extremes takes priority over momentum.

How Conviction Scoring Works

Think of the conviction score as a confidence meter. It adds up evidence from many different sources — price trends, insider buying, institutional holdings, and the broader economy. The more sources that agree, the higher the score. Conflicting signals bring it down. The result is a single number that summarizes how strong the evidence is that something significant is happening.

A conviction score is not a prediction — it is a measurement of the weight of evidence present in the data. A score of 80 does not mean "80% chance of moving up." It means 80 points worth of directional signals are simultaneously active across technical, institutional, and macro layers. The interpretation of that weight depends on the regime context.

Mark Minervini's Stage 2 and VCP Detection

Beyond Richard Wyckoff's accumulation and distribution framework, MarketTriage incorporates Mark Minervini's SEPA methodology (Specific Entry Point Analysis) for equities. Minervini's Stage 2 Trend Template identifies stocks in a confirmed institutional-quality uptrend — the structural sweet spot where price, moving averages, and proximity to highs align.

Stage 2 Trend Template (Equities Only)

An equity qualifies for Stage 2 when all five criteria are met simultaneously: price is above the 50-day moving average, the 50-day is above the 150-day, the 150-day is above the 200-day, the 200-day SMA is rising, price is at least 30% above its 52-week low, and price is within 25% of its 52-week high. When confirmed, the Stage 2 template contributes 15 conviction points (bullish) and replaces the generic "healthy uptrend" as the chart-long signal in protocol admission for equities. This is one of the highest-quality structural filters in the algorithm — stocks meeting all five criteria are, by definition, in a confirmed institutional accumulation phase.

Volatility Contraction Pattern (VCP)

The VCP is Minervini's signature base pattern: a series of progressively tighter price contractions with declining volume, indicating that supply is being absorbed by institutional buyers. MarketTriage detects VCPs algorithmically by dividing the last 40 trading days into four 10-day windows, measuring the percentage range of each, and confirming sequential contraction (each window ≤ 70% of the prior) with declining volume (< 85% of the 50-day average).

A VCP breakout fires when price closes above the pivot high of the tightest contraction window on at least 1.5x average volume — earning 25 conviction points (bullish). When a VCP breakout coincides with a full Minervini Stage 2 template, an additional 15-point confluence bonus is applied. If the asset also leads the S&P 500 on relative strength, another 10-point bonus is added. This combination — VCP breakout + Stage 2 + relative strength leadership — represents one of the highest-conviction entry setups in the entire algorithm.

VCP detection applies to all asset types (equities, ETFs, commodities, crypto). Stage 2 Trend Template is equities-only because the moving average stacking criteria are designed for stocks in institutional accumulation phases. VCP breakouts are not counted toward OBSERVATION thresholds — breakouts are post-base signals, not distress signals.

The Three-Column Triage Board

The MarketTriage dashboard organizes all 212 assets into three columns — CLEARANCE, OBSERVATION, and CAUTION — each mapped to a distinct trader intent. This is not arbitrary grouping: the column an asset appears in reflects both its regime classification and whether it has passed a multi-layer confirmation gate called protocol admission.

The protocol admission gate is the layer that separates OBSERVATION from CLEARANCE. An asset in CLEARANCE with a high conviction score still appears in OBSERVATION if it has not passed the 75% threshold across multiple signal categories — technical structure, institutional flow, and macro context. This prevents single-domain signals (for example, a golden cross with no volume confirmation and no institutional backing) from reaching the CLEARANCE column.

Assets classified as STABLE do not appear in any of the three columns. They are displayed in a collapsed grid below the main board — visible on demand but deliberately de-emphasized. In a universe of 212 assets, most will be STABLE at any given time. The dashboard surface area is reserved for assets where the data suggests something is happening.

Smart Money Signals: When Institutions Align

Most regime classification systems rely exclusively on price and volatility data. MarketTriage integrates two additional data layers that most retail traders cannot easily access: SEC Form 4 insider filings and quarterly 13F institutional holdings from 15 tracked institutional filers including Berkshire Hathaway, Bridgewater Associates, Renaissance Technologies, and Pershing Square.

Whale 13F Tracking

Every Friday, MarketTriage scans SEC EDGAR for new 13F-HR filings — the quarterly disclosure required of institutional managers with over $100M in assets. The system parses XML infotables, resolves CUSIP identifiers to ticker symbols, and compares current holdings against prior quarters to detect accumulation (new positions or increased shares) and distribution (reduced or liquidated positions). Whale accumulation contributes 12-20 conviction points (bullish); distribution contributes 12-20 points (bearish). When a whale is accumulating near 52-week lows, an additional 12-point bonus is applied. Read the full 13F whale tracking guide.

Insider Form 4 Clusters

SEC Form 4 filings capture insider transactions — purchases and sales by corporate officers, directors, and 10%+ shareholders. A single insider purchase is noise. Three or more insiders buying within a 90-day window is a cluster — and insider clusters at depressed prices are historically among the strongest predictive signals in equity markets. MarketTriage detects these clusters automatically via daily EDGAR scans.

The Alignment Signal

The most powerful signal in the algorithm is whale + insider alignment: when both institutional whales (via 13F) and corporate insiders (via Form 4) are simultaneously accumulating the same asset. This earns a 25-point confluence bonus and triggers an automatic OBSERVATION classification — bypassing the normal score and proximity gates entirely. The logic: if the people managing billions and the people running the company are both buying, that convergence of informed capital outweighs any price-based indicator.

Richard Wyckoff's volume-price framework explains why smart money alignment matters. During accumulation, large institutions absorb supply gradually — volume declines as sellers exhaust, and price stops making new lows despite persistent bearish sentiment. When On-Balance Volume (OBV) or the Accumulation/Distribution line diverges bullish while price remains flat, it signals that buying pressure is quietly building beneath the surface. The 13F and Form 4 data confirm who is doing the buying.

Gates and Safety Mechanisms

Regime classification is not simply "if score > threshold, assign regime." Between the raw signal data and the final classification, a series of gates filter out structurally unsound classifications. These gates exist because real markets produce signals that, while technically valid in isolation, are misleading in context. A bullish OBV divergence during a collapsing stock is noise — not accumulation. The gates catch this.

Why Gates Matter More Than Signals

Most quantitative trading systems focus on signal generation — the more signals, the better. MarketTriage inverts this: the gates that prevent classification are as important as the signals that trigger it. An asset with five accumulation signals during an active structural breakdown (expanding ATR, price making new lows) is more dangerous than one with zero signals. The decline stability gate catches exactly this scenario.

The credit circuit breaker is the most powerful gate in the system. When the ratio of high-yield bonds (HYG) to Treasury bonds (IEF) falls below its 200-day moving average, it signals that credit markets — which are historically more forward-looking than equity markets — are pricing in deteriorating fundamentals. In this state, MarketTriage blocks all long protocol admissions system-wide. Individual asset signals become secondary to macro credit stress.

Regime Transitions: How Markets Move Between States

A single regime snapshot tells the observer where an asset is now. A regime transition chain tells the story of how it got there — and what typically follows. MarketTriage tracks every regime change in an append-only table, creating a historical record of how assets have moved through the 6-state framework over time.

Transition coherence is a key quality signal. An asset moving CLEARANCE → ELEVATED → CRITICAL follows the natural exhaustion arc: trend confirmed, first warning, distribution confirmed. An asset jumping directly from CLEARANCE to CODE BLUE — skipping ELEVATED and CRITICAL — would indicate a sudden structural failure (a shock event, earnings collapse, or macro dislocation) rather than a gradual topping process.

Transitions tell a market story. Isolated regime snapshots do not. An asset in OBSERVATION that has been in OBSERVATION for 8 weeks after spending 12 weeks in CODE BLUE is forming a base — constructive. An asset in OBSERVATION that flipped from CODE BLUE yesterday after a single bullish candle is noise. The transition history provides the context that a single classification cannot.

Common Mistakes in Regime Interpretation

Market regime classification is a diagnostic tool, and like any diagnostic tool, it can be misread. These are the four most common interpretation errors observed in the MarketTriage framework.

How MarketTriage Automates Regime Classification

MarketTriage processes 212 assets through its regime classification pipeline automatically — equities (S&P 100 + meme stocks), ETFs (SPY, QQQ, 11 sector SPDRs), indices, commodities, and cryptocurrencies. Each asset is evaluated against 30+ signals from four data engines: CFTC COT data, SEC Form 4 insider filings, institutional 13F whale holdings, and Yahoo Finance OHLCV.

The result is a three-column triage board that separates the 212 assets into CLEARANCE, OBSERVATION, and CAUTION — with STABLE assets collapsed below. Regime transitions trigger alerts via Telegram, and every classification includes a conviction score, severity level, and narrative explanation describing the regime drivers in plain English.

How to Read the MarketTriage Regime Dashboard

The MarketTriage dashboard presents all 212 assets in a three-column layout designed around trader intent — what to pay attention to, what to watch, and what to avoid. Understanding the visual structure accelerates regime interpretation.

Three Columns, Three Intents

CLEARANCE (green) contains assets with a confirmed directional signal — regime is CLEARANCE or OBSERVATION, and the asset has passed the 75% protocol admission gate across multiple data layers. OBSERVATION (blue/yellow) contains assets with active signals that lack full confirmation — CLEARANCE, OBSERVATION, or ELEVATED regime without protocol admission. CAUTION (orange) contains assets where exhaustion or breakdown has been confirmed — CRITICAL or CODE BLUE regime.

STABLE assets are collapsed at the bottom of the dashboard. These assets show no active signals in either direction — the majority of the 212-asset universe at any given time.

Reading an Asset Card

Each card on the dashboard displays the asset name, regime label (CONFIRMED, WATCH, ACCUMULATING, WARNING, EXTENDED, or BREAKDOWN), current price, and conviction tier (high, moderate, or low). Clicking any card opens a detailed modal with holder and buyer narratives, regime drivers, the data layer protocol status, and a price chart.

Regime Transition Alerts

Above the three columns, an alerts bar displays recent regime transitions — assets that have moved between columns. These transitions are the most actionable events in the system: an asset moving from OBSERVATION to CLEARANCE indicates that protocol admission has been achieved, while a move from OBSERVATION to CAUTION indicates structural deterioration. Alerts include insider trading signals and macro context changes alongside regime transitions.

Regime Classification Approaches Compared

Market regime classification is not a single methodology — it spans academic finance, quantitative strategies, and practitioner frameworks. The foundational academic work is James Hamilton's 1989 regime-switching paper, which introduced Hidden Markov Models to economic time series. MarketTriage builds on this lineage while incorporating practitioner insights from Mark Minervini's SEPA methodology and Richard Wyckoff's volume-price framework.

The key distinction between MarketTriage and academic HMM approaches is input breadth. HMMs typically operate on returns and volatility alone — effective for capturing broad market states but unable to distinguish between an asset declining due to distribution (insiders selling, volume exhaustion) and one declining due to a sector rotation (no fundamental change). The multi-domain input layer — price, volume, institutional flow, and macro context — provides the structural granularity that position traders require.
