Zscaler edges lower as growth deceleration weighs on valuation

Zscaler shares slipped 0.12% to $260.15 on Oct. 27, trading near the midpoint of a 52-week range that stretches from $114.625 to $336.99. The cybersecurity firm's 25.4% revenue growth remains robust, but a negative EPS of -0.4 and a net margin of -1.9% keep profitability in question. The Alpha Score of 41.5 reflects a strong momentum sub-score of 66.6, offset by a quality score of 41.9; value and sentiment were not computed. With the stock roughly 23% off its 52-week high, investors are watching for signs of margin improvement or a catalyst to reignite the upward trajectory. Next week's quarterly results will test whether the growth narrative can sustain the current multiple.
