Medical instrument provider Intuitive Surgical is set to report second-quarter earnings results on Thursday after the bell. The maker of the popular da Vinci Surgical System, Intuitive Surgical is a Zacks Rank #2 (Buy) stock.

The established health care company has surpassed the earnings mark in each of the last four quarters. With the broader healthcare sector showing strength lately, is ISRG stock a buy?
