Veeva Systems Falls 1.5% as $550M Volume Ranks 201st in U.S. Equities

Veeva Systems (VEEV) closed 1.50% lower on October 3, 2025, with a trading volume of $0.55 billion, ranking 201st among U.S. equities for the day. The decline followed mixed signals from recent business developments and sector dynamics, though specific catalysts for the move were not immediately apparent from publicly available reports.

Recent activity centered on strategic positioning within the life sciences software space, with analysts noting ongoing competitive pressures in cloud-based data management solutions. While no material earnings revisions or regulatory updates were disclosed, market participants appeared to reassess long-term growth assumptions amid broader sector volatility. Trading patterns suggested short-term positioning adjustments rather than fundamental reevaluations.

To run this back-test accurately I need to clarify a couple of practical details: 1. Universe. • Do you want the entire U.S. equity universe (all listed common shares) or a specific subset (e.g. S&P 1500, Russell 3000, NASDAQ/NYSE only, etc.)? 2. Execution price & timing. • Should we “buy” the 500 highest-volume names at the close of each trading day and exit them at the next day’s close (close-to-close returns)? • Or enter at next day’s open and exit at that same day’s close (open-to-close)? 3. Transaction costs / slippage. • Should any trading cost assumptions be applied, or can we run it cost-free for an initial pass? Once I have that information I can generate the daily signals, feed them to the back-testing engine, and return the performance statistics.
