ISRG, -4.58 sank 4.6 toward a two-month low in midday trading Wednesday, after the surgical robotics company provided a revenue outlook that was slightly below expectations, as COVID resurgences impacted procedure volumes in China. The company expects fourth-quarter revenue to rise 7 from a year ago to 1.66 billion, which is shy of the FactSet consensus of 1.69 billion.
