Regime Scan applies the same dual-channel structural detection framework used for the S&P 500 to individual sector ETFs. However, not all sectors respond to the framework identically. Each sector has been independently validated, and sector-specific alert filtering rules have been calibrated to maximize signal quality for that market.
The three sectors currently monitored — Energy, Utilities, and Financials — were selected because they provide independent, non-redundant structural information. Sectors with high correlation to the S&P 500 (Technology, Industrials, Healthcare, Consumer Discretionary) are excluded because their signals are largely redundant with the broad market monitor.
The full detection framework transfers directly to the energy sector. All elevated signals are surfaced without additional filtering. Energy markets are driven by supply dynamics, geopolitical factors, and demand cycles that operate with meaningful independence from broad equity markets. The framework has detected structural deterioration before major energy sector drawdowns with a validated hit rate and positive return separation between ALERT and non-ALERT periods.
For utilities, only the sequential escalation pattern is surfaced — the distribution channel must identify stress first, followed by independent confirmation from the stability channel within 30 days. Standalone signals from either channel produced weak results in this rate-sensitive sector, but the escalation pattern — where both channels confirm sequentially — has shown the highest historical reliability. When you see an alert here, both detection channels have confirmed independently. This is the highest-conviction detection configuration.
For financials, only the stability channel generates alerts. The distribution channel produces excessive noise in this sector due to the unique statistical characteristics of financial sector returns (fat tails, leverage-driven dynamics). Stability-based detection alone has shown strong reliability for financials, including detection of structural deterioration during the 2007-2008 financial crisis.
Sector signals should always be interpreted alongside the broad market monitor. When the S&P 500 enters ALERT, sector conditions take on additional significance. Conversely, sector-specific deterioration during an S&P 500 CLEAR period may indicate localized stress rather than systemic risk.
Sector-specific calibration is based on limited historical data compared to the S&P 500 (backfilled from 2020 for the live system, with historical backtest validation). The filtering rules were validated on available history but may not capture all meaningful events. The number of historical alert signals per sector is small, which limits statistical confidence in hit rates. New sectors may be added as validation is completed.
