What it checks

Decompose a focal ticker's Wikipedia pageview attention spike into shared vs idiosyncratic components by co-movement with its TNIC-peer / sector cohort's pageview spikes on the same days.

Mechanism

Decompose a focal ticker's Wikipedia pageview attention spike into shared vs idiosyncratic components by co-movement with its TNIC-peer / sector cohort's pageview spikes on the same days. When a spike is largely SHARED (high joint, low idiosyncratic) the next 1-2 week return reverses (diffuse low-precision retail attention overshoots); idiosyncratic firm-specific spikes drift.
