CONTAGION SCANNER
When one stock moves,
which peers follow?
A 4%+ move in one ticker triggers a cascade scan across correlated peers. The contagion map shows which correlated peers haven't moved yet.

SECTOR CONTAGION SUMMARY
Free tier: sector-level view. Unlock with All Access for ticker-level drill-down.
Sector contagion
The correlation feed publishes ticker-pair
correlations and the active flags from its most recent run. It publishes no sector aggregation, so this
sector rollup stays empty rather than showing a figure nothing measured.
Active Contagion Signals
Per-signal rows are not published by the feed
The correlation feed publishes a count of contagion signals firing as of its most recent run, and no per-signal rows. This table stays empty rather than showing rows nothing produced. The network map above shows the feed's latest run.
HOW CONTAGION SCANNING WORKS
From price shock to trading signal in 4 steps
01
Detect
When any ticker moves >4% intraday, it triggers a contagion scan against its peer group.
02
Correlate
252-day rolling correlation calculated for every peer. Only peers with correlation >0.50 are flagged as potential cascade targets.
03
Score
Composite contagion score generated from correlation strength, move magnitude, options IV data, and peer's current move (confirmed vs diverging).
04
Label
Signals scoring above 100 are tagged HIGH. Each one is labelled a call when the ticker that moved first went up, a put when it went down, or a straddle when its direction is unclear. A peer already moving against the first ticker's direction is tagged DIVERGING and its score is multiplied by 0.3.

Sector-level cascades are shown to every visitor. Ticker-level nodes, correlation scores and labels are part of a paid plan.
