ISRG · PEAD ↑ 68

Intuitive Surgical reported Q3 2026 EPS of $2.53 on 2026-10-20, beating the $2.13 consensus by $0.40 (+18.8%).

Print-day reaction was a modest +1.1% versus the prior close, a muted immediate move relative to the size of the earnings beat. The overnight gap to the T+1 open was sharply negative at -8.1%, suggesting significant after-hours selling pressure that unwound much of the prior session's gains. Over days 1 through 3, the stock recovered and then extended strongly, drifting +5.6% from the T+1 close to the T+3 close — decisively reversing the overnight fade. Cumulative abnormal return of +5.3% versus SPY.US clears the long threshold; the PEAD read is held through 2027-01-15.
