CEO Michael Mahoney bought $9M worth of BSX at $48.33, establishing his first-ever long position after executing seven prior sales totaling over $100M. This is a highly significant reversal from a serial seller to a major buyer, signaling a potential inflection point in his view of the company's value. Bull: strong analyst consensus and a 17% discount to recent highs → target $58; bear: breaks $42 support.
Where it could go — Our 7-8 conviction officer buys: 61% beat SPY at 30d; bull holds $48, bear breaks $42.
