The Q2 beat was overshadowed by the guidance cut and restructuring, creating a tug-of-war between value-oriented buyers (Norges, Jane Street) and momentum-driven sellers (Fidelity, JPMorgan). The $9.4M insider buying suggests management sees value, but the net $4.12B institutional outflow signals caution. Monitor Q3 2026 earnings for execution on the restructuring and whether the lowered guidance proves conservative or is further reduced.
Executive Summary
Boston Scientific's Q2 2026 earnings beat was overshadowed by a significant guidance cut and a $700M-$800M restructuring plan, leading to a mixed institutional cluster in Q2 2026. 35 buyers accumulated $1.36B in net new positions, led by Norges Bank's new $903.5M stake and Jane Street's $262.9M addition, while 54 sellers reduced holdings by $5.48B, including large trims from Fidelity (-$2.71B) and JPMorgan (-$1.06B). The net selling pressure of $4.12B, combined with insider buying of $9.4M, suggests institutions are divided on the stock's near-term outlook following the guidance revision.
