Zscaler Ranks 287th in Trading Volume as Vanguard Boosts Stake and Analysts Raise Targets to $365

On August 11, 2025, Zscaler (ZS) traded at a 0.55% gain with a trading volume of $350 million, down 22.78% from the prior day, ranking 287th in market activity. Institutional ownership of the cybersecurity firm expanded as Vanguard Group Inc. increased its stake by 3.1%, now holding nearly 9.9 million shares valued at $1.96 billion. Mizuho Markets Americas LLC also entered a new position with 49,950 shares worth $9.91 million during Q1. Meanwhile, several institutional investors, including GAMMA Investing LLC and Allworth Financial LP, raised their holdings by 43.1% and 47.4%, respectively, reflecting growing confidence in the stock.

Analyst sentiment remained bullish, with 29 buy ratings and elevated price targets. Evercore ISI raised its target to $290, while UBS Group set a $365 objective, the highest among recent revisions. Despite a negative net margin of 1.52%, Zscaler reported 22.6% year-over-year revenue growth in Q2, surpassing expectations. However, insider transactions highlighted mixed signals, as executives Syam Nair and Adam Geller reduced their holdings by 20.75% and 7.26%, respectively, over the past three months.

A backtested strategy of purchasing the top 500 stocks by daily trading volume and holding for one day achieved a 166.71% return from 2022 to the present, outperforming the benchmark by 137.53%. This underscores the influence of liquidity concentration in driving short-term gains, particularly in volatile markets where high-volume stocks experience amplified price movements due to sustained investor interest.
