1. Why Catalyst Windows Matter
When giant market cap stocks like Meta or Nvidia embark on historic multi-year best monthly runs, the key question for institutional traders is how much of the surge is intrinsic product momentum versus index drift.
2. Isolating Alpha with CAR
Cumulative Abnormal Return (CAR) subtracts market beta exposure. If the Nasdaq rallies 4% and a stock with β=1.25 climbs 28%, the model attributes +23.1% directly to the AI assistant catalyst effect.
3. Volume Velocity Confirmation
Authentic catalyst rallies exhibit distinct institutional accumulation footprints: a 2x-3.5x average daily volume breakout on Day T+0, followed by sustained volume drift as consensus estimates are revised upward.
