What Happened?
Shares of cloud security platform Zscaler (NASDAQ: ZS) jumped 8.3% in the afternoon session after cybersecurity peer Fortinet reported strong earnings.
When a major player in a sector beats expectations, investors often rotate into related names on the assumption the tailwinds are industry-wide. Beyond the sector lift, Zscaler has its own positive catalysts in play. The company raised its full-year Annual Recurring Revenue (ARR) guidance to $3.73–$3.745 billion, implying 24% growth, up from its prior 23% forecast, signaling management's confidence in demand. Zscaler is scheduled to report its own Q3 fiscal 2026 earnings on May 26, and the move suggests traders are positioning ahead of that print with optimism.

What Is The Market Telling Us
Zscaler’s shares are quite volatile and have had 19 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.
The previous big move we wrote about was 6 days ago when the stock gained 2.5% on the news that strong earnings and upbeat forecasts from several peers boosted the broader software sector.
he gains appeared driven by positive sentiment across the software-as-a-service (SaaS) space. For instance, enterprise software maker Atlassian saw its shares surge after lifting its annual forecast, which in turn lifted peers like Salesforce and ServiceNow.
Similarly, Twilio's stock jumped after it reported first-quarter revenue that beat estimates and raised its own forecast, with its CEO highlighting artificial intelligence as a catalyst. This positive news from peers helped create a favorable environment for software stocks, which some strategists noted had been underperforming the broader market and were potentially positioned for a comeback.
Zscaler is down 31.6% since the beginning of the year, and at $150.94 per share, it is trading 55.1% below its 52-week high of $336.27 from November 2025. Investors who bought $1,000 worth of Zscaler’s shares 5 years ago would now be looking at only $891.47.
