ISRG · PEAD ↓ 91

Intuitive Surgical reported Q2 2026 EPS of $2.37 on 2026-07-16, beating the $2.02 consensus by $0.35 (+17.3%).

Print-day reaction was +3.4% from the prior close, as shares rallied through the session on the EPS beat. The overnight gap to the T+1 open, however, reversed sharply at -9.3%, signalling aggressive after-hours selling that erased the print-day gain. Over the following two trading days (T+1 close through T+3 close), the stock drifted a further +1.3%, but this modest recovery failed to recoup the overnight collapse. Cumulative abnormal return of -9.1% versus SPY.US places ISRG firmly in PEAD short territory; per the documented pattern, the read holds through 2026-10-13.
