Knifecatcher
Board steps in with €50k+ after the stock dropped 5–25%.
The most aggressive screen in the lineup. When a director buys into a real pullback — not a wobble, not a crash — they're explicitly disagreeing with the market. Hit rate is lower (54%) but the right tail is enormous when it works.

Contrarian momentum bet — when the dip was overdone you win, when it wasn't you compound the loss. Hit rate of 54% is barely above a coin flip; the edge lives in the magnitude of winners (up to +35%) vs losers (capped near −16% in backtest). Don't average down on losing alerts from this screen.
