This is a heuristic ordering under the current rules, not a calibrated return forecast. It explains why candidates rank differently; the public-filing evidence and data limits are shown below.
Why there is no buy signal
No qualifying open-market purchase disclosure is available in the current research window. This is not a sell signal.
The underlying disclosures remain available below for audit.

Insider profile outcomes
Historical performance following insider filings. The company role is translated below each name while preserving the original title.
- Excess return = stock return − OMX Stockholm 30 return over the same period.
- Hit rate = completed events with positive excess return ÷ total 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.
- Small-sample rule: n<5 is shown for transparency and is not scored.
Events are disclosure-level observations; related disclosures published on the same date may share a return path and may not be statistically independent. This research enrichment does not affect the insider score or ranking.
