Zscaler Surges on Earnings Beat Despite Drop in Volume, Remains Day’s Top Trade

Market Snapshot

On March 30, 2026, Zscaler (ZS) closed with a 3.08% gain, despite a notable 29.12% drop in trading volume to $400 million, which ranked as the highest-volume stock of the day. This is in contrast to the previous session's average volume, which was significantly higher. The stock’s strong performance was a positive deviation from the lighter-than-average trading activity. Meanwhile, Zscaler’s shares traded as high as $140.99, up from its prior close of $133.16, reflecting a notable upward move in the market. This increase came despite mixed analyst ratings and ongoing insider selling.

Key Drivers

Zscaler’s stock rallied in part due to the company’s strong quarterly earnings report, which exceeded expectations. The company posted earnings per share (EPS) of $1.01, beating the estimated $0.89 by $0.12. Revenue also surged to $815.75 million, a 25.9% increase year-over-year. The positive results signaled strong operational momentum, particularly in a competitive cybersecurity market. Additionally, Zscaler provided FY2026 guidance of $3.99–$4.02 EPS, which suggests continued optimism about future performance. These results were a key catalyst for the stock’s 6% rise earlier in the week, despite the lower volume on March 30.

Beyond the earnings beat, Zscaler’s strategic focus on AI security and its Zero Trust architecture appears to be resonating in the market. The company has been expanding its customer base, particularly in enterprise markets, which has contributed to sustained growth. The recent integration of acquisitions and product innovations appear to be reinforcing the company’s competitive positioning. This strategic emphasis has drawn attention from analysts and investors, with several institutions increasing their stakes in the stock. For example, SG Americas Securities LLC significantly boosted its position in Q4, acquiring shares worth approximately $26.12 million.

Analyst activity also played a role in shaping the stock’s trajectory. Zscaler received a range of ratings, from "Strong Buy" to "Strong Sell," reflecting varying views on the stock's short-term prospects. Rosenblatt Securities maintained a "Buy" rating with a $280.00 price target, while Zacks Research downgraded its rating to "Strong Sell" in early March. Despite the mixed signals, the consensus rating remained "Moderate Buy," with an average price target of $267.13. Analysts’ emphasis on the company’s long-term growth potential, particularly in cloud security, may have supported investor sentiment. However, recent insider selling activity, including sales by CEO Jagtar Singh Chaudhry and others, introduced some uncertainty. Over the past 90 days, corporate insiders sold approximately 12,783 shares worth $2.04 million, raising questions about internal confidence in the company’s stock.

Financial metrics further underlined the complexity of the company's positioning. Zscaler’s gross profit margin remained steady at around 77%, but operating expenses continued to outpace revenue growth, contributing to ongoing net losses. The company reported a negative net margin of 2.25% and a return on equity of 0.06%, indicating that profitability remains a challenge despite revenue expansion. Additionally, the stock's 50-day and 200-day moving averages of $170.54 and $237.66, respectively, showed that the stock is currently trading below its historical averages, which may signal some short-term undervaluation in investor minds.

Finally, institutional ownership trends and recent inflows suggest that Zscaler is gaining traction among larger investors. Institutional investors hold 46.45% of the company’s stock, and several firms, including Prudential Financial Inc., have significantly increased their positions in recent quarters. This institutional confidence could help stabilize the stock amid volatile retail trading behavior and analyst divergence. While the stock’s current price-to-earnings (P/E) ratio of -336.90 reflects the company's unprofitability, its market cap of $22.75 billion highlights investor appetite for its growth story. These factors combined created the environment that enabled the stock’s upward movement despite its recent earnings and sentiment challenges.
