Gartner's Stock Climbs 1.62% Amid 20.59% Volume Drop Slides to 231st in Market Activity Rankings

On September 16, 2025, , ranking it 231st in market activity. The stock’s performance coincided with mixed signals from the firm’s strategic outlook on AI integration.

Gartner analysts emphasized that Fortune 500 companies are unlikely to fully automate customer service roles in the near term, according to , a senior researcher at the firm. While AI is expected to reduce the number of human agents, Ross noted that a completely agentless model remains impractical, highlighting ongoing demand for hybrid solutions. This perspective aligns with broader industry trends where IT leaders prioritize balancing automation with human oversight.

Separately, a Forrester study highlighted the critical role of IT departments in managing AI adoption, a domain where Gartner’s research and advisory services are central. The study found IT leaders are best positioned to orchestrate AI initiatives, reinforcing the firm’s relevance in guiding enterprises through complex technology transitions. However, the report also underscored challenges, including fragmented governance policies and the need for updated frameworks to address emerging risks.

To run this back-test accurately we need to nail down a couple of practical details: 1. Market universe – “all stocks” can mean different things (e.g., U.S.-listed common shares, MSCI World constituents, etc.). 2. Data coverage – identifying the 500 highest-volume names each day requires daily volume data for the whole universe, so we need to know which exchange(s) or index membership list to pull. 3. Position sizing – should the 500 stocks be equal-weighted each day, or weighted by something else (e.g., their dollar volume share)? 4. Transaction assumptions – buy at that day’s close and sell next day’s close, or open-to-open, etc.? (If you don’t have a preference I can default to close-to-close with equal weighting.) Could you confirm or refine the universe (e.g., “all U.S. common stocks traded on NYSE/Nasdaq/AMEX” or “current Russell 3000 members”) and let me know whether equal-weight, close-to-close is acceptable?
