Each sector ETF is monitored using the same dual-channel structural detection framework as the S&P 500, but with sector-specific alert filtering calibrated to each market's characteristics.
The full detection framework applies to the energy sector. All elevated signals are surfaced. Energy markets are driven by supply, demand, and geopolitical dynamics that operate independently from broad market conditions.
For utilities, only the sequential escalation pattern is surfaced — distributional stress confirmed by structural breakdown. This specific pattern has shown the highest historical reliability for this rate-sensitive sector. When you see an alert here, both detection channels have confirmed independently.
For financials, only the stability channel generates alerts. The distribution channel produces excessive noise in this sector due to its unique return characteristics. Stability-based detection alone has shown strong reliability, including detection of the 2007-2008 financial crisis 76 days before the Lehman collapse.
Sector-specific calibration is based on limited historical data. The filtering rules may not capture all meaningful events. Cross-reference with SPY state for broader context.
