• Zscaler (ZS) shares have put together a massive short-term recovery, surging roughly 50% since early April. But that still puts it 50% below its 2025 all-time high.

• The stock currently carries a 25% “Sell” overall average from Barchart Opinion’s composite indicator, but its near-term price action tells a far more bullish story. So does the fact that this same measure was 56% “Sell” one week ago and 100% “Sell” one month ago. The trend is ZS’s friend.

• ZS went to Trend Seeker “Buy” status on May 8, the first time that has occurred during 2026.

• Despite macro headwinds, growing adoption of zero-trust architecture has prompted a major short-covering rally ahead of ZS’s May 26 earnings release.

ZS has rallied from its deep 52-week low around $115 just 5 weeks ago, in early April. Its 20-day moving average is strong, and its 50-day moving average just turned positive this month. The PPO indicator has recently undergone a bullish crossover in both daily and weekly time frames, a sign of increasing momentum.

Following a steep price decline of more than 60% which began last November, driven by software sector growth fears, Zscaler has successfully broken out of its bottoming formation.
