Big gains for the stock market Friday, albeit in lower volume, resulted in a nicely expanded new-highs list. But the session was curiously light on breakouts, a common theme in recent weeks.
Intuitive Surgical (ISRG) rose 6.75 to 580.45. It closed just above a 580.10 entry, but there wasn’t much conviction behind the buying. Volume rose from Thursday’s level but was still well below average.
