Director Tyler Lauren M bought $149K worth of COR shares, increasing their stake by 14.4% at $270.23, which is 17.7% below the 90-day high. This first-ever purchase combined with another director's $2.2M buy creates a meaningful cluster signal despite the modest individual trade size.

Where it could go — 66.7% of similar setups result in positive 90-day returns; watch $284.93 as the bull trigger, $261.29 as the bear break.

Director Dermot Durcan bought 4,000 shares of COR at $274.19 on June 18, adding $1.1M and lifting his stake 14.4% to 31,767 shares — his second identical-sized purchase in 21 days, bringing his combined outlay to $2.2M since May 28. Two back-to-back $1.1M buys from the same director in rapid succession is an unusual pattern of accumulation that goes beyond routine portfolio management, especially with earnings 47 days out and 16 of 20 analysts already at Buy. Bull: sustained accumulation above $261 support into the August 4 print targets a retest of the $332 90-day high; Bear: breaks $261 (30-day low) and the thesis unravels.

Where it could go — Broad base rate 62.5% positive at 90d; bull holds $261, bear breaks $261 and tests $244.

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.
