REGIME ENGINE V19.0-US

US Market Regime Engine
Reading the market's vital signs.

Before analyzing individual stocks, we first identify where the market actually stands. Built on the same modeling principles as our Korean engine — and fully redesigned for the structural dynamics of US equity markets.

Replacing intuition with objectivity

Overcoming the limits of stock-level analysis when the entire market is in freefall.

The problem with conventional top-down analysis

  • In broad market crashes, even strong fundamental analysis becomes irrelevant
  • Human intuition distorts at peak fear — leading to systematic timing errors
  • Simple indicator aggregation causes signal interference and double-counting

What the Regime Engine solves

  • Classifies the current market as risk-accumulating, fracturing, or stable — enabling precise asset allocation
  • Clusters correlated indicators into blocks; uses representative values with dynamically-weighted regime calls
  • A forced circuit-breaker activates when risk crosses critical thresholds — setting a hard floor on exposure

Engine Architecture

How 7 macro variables flow through system filters and convert into a 6-stage regime matrix.

Seven Indicators. Three Blocks.

Designed with built-in conditional weighting — not simple aggregation.

Block 01

Sentiment & Liquidity

Tracks fear extremes and the direction of global capital flows into US markets. Detects short-term, high-velocity risk signals before they appear in price.

Block 02

Credit & Rates

Monitors corporate funding stress and the health of the yield curve structure. Detects genuine fractures in the market's internal scaffolding before they become visible.

Block 03

Macro Fundamentals

Reflects employment and inflation dynamics. Captures heavy, structural signals that take longer to reverse — the kind that cause prolonged bear markets rather than sharp corrections.

26-Year Full Backtest Results

~6,600 trading days of data run through the engine. This is the actual regime classification record.

Historical Crisis Period Mapping

  • Dot-com bubble and financial crisis: Major crisis regimes captured with no gaps in coverage
  • 2020 COVID crash: The brief, violent V-shape shock correctly reflected as a narrow crisis window
  • 2022 inflation bear market: Correctly classified as a prolonged bear, not a systemic crisis

Short-Term Regime Shift Sensitivity

  • Mid-bull signals are not noise — they represent genuine risk variance periods within uptrends.
  • 2015–16 yuan shock, Q4 2018 rate selloff, August 2024 yen carry unwind — all captured as trend deviations
  • Long-term crisis defense and short-term volatility response are deliberately balanced — sensitivity is precisely calibrated

GOLDILOCKSMaximum macro stability; volatility suppressedRisk premium removed; maximum allocation justified
BULLStrong upward momentum driven by sentiment and liquidityMaintain trend-following; maximize position intensity

UNSTABLEShort-term volatility spike; partial macro warning signalsReduce new entry weight; heighten risk monitoring
BEARStructural credit/rate stress accumulating; downtrend establishedConservative positioning; gradual cash increase
CRISISSystemic risk threshold breached; circuit breaker activatedCapital preservation first; full defensive mode
