Read this honestly
This is a base rate from PANW's own history — what happened after prior visits to this extreme — not a prediction. 22 prior cases is a guide, not a guarantee. Extremes can persist far longer than they "should."
How Rarity Radar works
We measure PANW on several conditions (distance from its 200-day average, RSI, recent momentum) against its own 10-year history, then surface the single most extreme one and the empirical forward returns that followed prior visits to that extreme.
