Verdict

no verdict yet

23 of the 60 sessions before the first reading. No verdict until then.

The hypothesis, as registered

Medium-term winners keep winning, as long as they are not yet stretched. The oldest documented equity anomaly, tested on a one-session horizon.

The rule

Tradable stocks above their three moving averages, ahead of SPY over 20 days, RSI under 70. Take the highest 20-day return.

Registered on 2026-09-07. Neither text has changed since, and neither will: a strategy that needs amending is retired and a new one registered in its place.

Session by session

Newest first. The numbers in the middle column are the ones the rule actually read that morning. Losing days stay.

Best session +12.17%, worst -13.63%. Over this few sessions the mean is mostly the sum of its two or three largest days, which is the whole reason the verdict is read only after 60, 120, 250, 500 sessions and frozen in between.
