Verdict

no verdict yet

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

The hypothesis, as registered

A stock that gapped up on heavy volume yesterday is still being bought today. This is the movement queue of the product's own screen, but signed: only upward gaps qualify.

The rule

Across the whole tradable universe (average volume over 1M, price over $5): yesterday's opening gap at least +2% with relative volume at least 1.5×. Take the largest gap. On a hundred replayed sessions this profile had the highest mean and a median below zero — it is registered to find out which one persists.

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 +4.58%, worst -4.27%. 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.
