Zscaler Rises 0.85% Amid $350M Volume Rank 343rd as Cybersecurity Firm Expands AI-Driven Security with Red Canary Acquisition

Zscaler (ZS) rose 0.85% on August 13, with a trading volume of $350 million, ranking 343rd in market activity. The cybersecurity firm recently completed its acquisition of Red Canary, aiming to enhance agentic AI-driven security operations. Analysts from Evercore ISI and Cantor Fitzgerald have maintained bullish stances, while IGEL expanded its zero-trust capabilities through a partnership with Zscaler’s client connector. Red Canary’s research also highlighted a surge in cloud and identity threats, underscoring Zscaler’s strategic positioning in addressing evolving cybersecurity risks.

Shareholder activity showed mixed signals, with institutional investors like Vanguard Group and SouthState Corp increasing stakes, while entities such as Allianz Asset Management and J. Safra Sarasin reduced holdings. Zscaler’s short interest spiked 5,477.6% in July, indicating heightened speculative pressure. Meanwhile, brokerages assigned a “Moderate Buy” rating, with a consensus price target of $296.82. The company announced plans to host its Q4 2025 earnings call, though recent analyst questions focused on margin pressures and guidance adjustments at competitors, indirectly influencing market sentiment.

The strategy of buying the top 500 stocks by daily trading volume and holding them for one day from 2022 to present yielded a 1-day return of 0.98%, with a cumulative 31.52% gain over 365 days. This suggests the approach captured short-term momentum but remained exposed to market volatility and timing risks.
