BULLISH
Director Dermot Durcan makes first-ever $1.1M buy in COR, adding 17% stake near 90-day low.
39d ago

Director Dermot Durcan bought $1.1M in COR at $266.26 per share, increasing his stake by 16.8% at a price just 9% above the 90-day low. As a first-time buyer entering near a significant low, this suggests a personal conviction that the stock's recent decline is overdone. Bull: a hold above the $244.26 low could target a reversion toward the $312.97 30-day high, representing a 17% gain.

Where it could go — No similar COR signal history; broad base rate 0% positive at 90d; bull holds $244, bear breaks $244.
