GOOGL just had its biggest 20-day run since Dec 2025
GOOGL's 20-day move is at +14% — biggest 20-day run, in the top 5% of its 10-year range. The last 23 times GOOGL reached this extreme, the median move over the next 15 trading days was +1% (52% finished higher).
This is a base rate from GOOGL's own history — what happened after prior visits to this extreme — not a prediction. 23 prior cases is a guide, not a guarantee. Extremes can persist far longer than they "should."
How Rarity Radar works
We measure GOOGL 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.
