Every bear market in modern history arrived with a paper trail. Credit spreads widened. Breadth narrowed. The yield curve did something uncomfortable. Payrolls softened at the margin. None of it made the front page, because none of it looked like a crisis yet.
By the time it does look like a crisis, the drawdown has already happened.
That gap — between when the economy changes and when consensus admits it — is the entire opportunity in market regime detection. And it is the problem RegimeSignal™ was built to solve.
Regimes, not forecasts
Most stock market prediction fails because it asks the wrong question. “Where will the S&P 500 be in December?” is close to unanswerable. “What state is this market in, and what usually happens next from here?” is a far more tractable problem — and a far more useful one.
Markets do not move randomly between conditions. They occupy regimes: durable bull expansions, brittle pullbacks, corrections that deepen, bear markets, and the recoveries that follow. Each regime has its own statistical signature in economic and market data. Detect the shift early, and you are not guessing at price targets — you are recognizing that the rules just changed.
Built on the economy, not opinion
Most market calls run on instinct. RegimeSignal runs on the economy itself.
The framework reads 24 live Federal Reserve economic series — the yield curve, CPI and core inflation, credit spreads, payrolls, jobless claims, industrial production, housing, money supply, the Fed balance sheet — and fuses them with real-time price, volatility, breadth, sentiment, and AI-scored news flow. More than 30 live data streams in total, refreshed every market day, with sentiment history reaching back to 1987.
When the economy shifts, it shows up in the data weeks before it shows up in the narrative.
Four signals, one full cycle
RegimeSignal covers the complete S&P 500 cycle with four independently constructed, walk-forward validated models:
- BRS (Bear Regime Signal™) — bear regime formation, ~86% precision across 304 out-of-sample months
- MBS Tier 1 — 5% pullbacks ahead of the move, ~83% precision
- MBS Tier 2 — 10% corrections roughly four months out, ~84% precision
- RRS (Regime Recovery Signal™) — bull recovery confirmation, so you re-engage on evidence rather than on a headline bounce
Each stage of the cycle has a dedicated signal — from a −5% pullback warning through to confirmed recovery.
Average precision across the four sits near 84%, with an aggregate false-positive rate around 4% and an average forward window of about four months. Every financially-driven S&P 500 bear regime since 1990 was flagged ahead of time — 1990, 2000, 2007, 2011, 2015, 2018, 2022 and 2025.
Honest about the edges
The claims come with their limits attached, which is unusual enough to be worth stating plainly.
COVID-19 in March 2020 is excluded as an exogenous shock — no economic model saw a pandemic coming, and pretending otherwise would be dishonest. The recovery signal’s 82% figure is in-sample; its prospective estimate is closer to 69% on a small sample of eleven fires. The Bull and Bear Velocity gauges are directional context, deliberately excluded from the validated four-signal count.
Two independent PhD-level reviews examined the framework in 2026. Both concluded validated with qualifications, and both are made available to subscribers rather than summarized away.
