Another View: Is the Price Too High?

Looking through another lens, Zscaler's price-to-sales ratio stands at 18.5x, far above both the US Software industry average of 5.1x and its own peer group average of 19.1x. More importantly, this ratio is even higher than the fair ratio of 13x that the market could eventually gravitate toward. Such a premium suggests investors are betting heavily on rapid future growth, but it could also spell risk if expectations slip. Does the market’s optimism set the stage for future disappointment, or will Zscaler’s expansion surprise on the upside?
