Zscaler Stock Jumped 17% in a Day. Was the Move Earned?
Zscaler (ZS) stock surged 16.52% to $191.73 on September 14, driven by broader sector gains following AI safety concerns. The company reported Q4 revenue of $898.19M, up 24.88% YoY, and adjusted earnings of $1.19, beating estimates. However, the stock initially fell 4.5% post-earnings due to slower growth outlook.
