- Hit rate = positive excess-return events ÷ completed events.
- Price coverage = valid point-in-time prices ÷ events mature enough for that period.
- Returns start on the first shared trading session on or after publication.

Counts are profile-wide, point-in-time research labels. They never affect the insider score or ranking.
Every completed outcome is shown; n<5 is descriptive small-sample evidence and is not scored. Disclosure-level observations published on the same date may share a return path and may not be statistically independent. These results never affect the insider score or ranking.
