Pure size-as-signal. No filters for momentum or context — just the raw conviction of a director writing a quarter-million-euro cheque. Hit rate is the lowest of the core screens (55%), so this one is more about big wins than consistent base hits.

How the rule fires

Insider role = Board · transaction is a buy · value ≥ €250,000.

⚠️ Risks

Some of the biggest losses in the whole study live in this cohort — Rieter Holding (−52%) and Cicor (−21%) had board buys right before profit warnings. Big size doesn't equal smart timing. Median return is only +0.7%, so the mean lives in the right tail.
