Waters Shares Climb 2.01% on European Diagnostic Pact, $240M Volume Lands 450th in U.S. Liquidity Rankings

Waters (WAT) closed higher by 2.01% on October 3, 2025, with a trading volume of $0.24 billion, ranking 450th in terms of liquidity among U.S.-listed stocks. The move followed a strategic partnership announcement with a European diagnostics firm, which expanded its market access in key therapeutic areas. Analysts noted the collaboration could accelerate adoption of Waters' chromatography solutions in regulated healthcare sectors.

Recent regulatory filings highlighted a 12% year-over-year increase in R&D expenditures, reflecting sustained investment in mass spectrometry innovation. Institutional ownership data showed a 4.3% net inflow in the preceding week, primarily from biotechnology-focused funds seeking exposure to laboratory equipment resilience amid sector volatility.

To run this back-test properly I need to clarify a couple of points and make sure the data we pull matches exactly what you have in mind. 1. Market / universe • Do you want all primary-listed U.S. common stocks (≈4 000 names) ranked by daily share volume, or a different universe (e.g., only S&P 500 constituents, only Nasdaq, HK stocks, etc.)? 2. Definition of "buy" and "hold one day" • Is the intention "buy at today’s close, sell at tomorrow’s close" (close-to-close return), or "buy at tomorrow’s open, sell at tomorrow’s close"? • Equal-weight across the 500 names each day, no transaction costs or constraints unless you specify otherwise? 3. Practical data volume • A fully dynamic daily ranking over >3 years involves fetching and processing thousands of securities per day. • If you’re OK with a simplified approach (e.g., a fixed list of the 500 names with the highest average volume since 2022), we can run the test much faster. • Alternatively, we can proceed with the full daily re-ranking, but it will take longer for the tools to finish the data pulls. Please let me know your preferences on the above so I can set up the data retrieval plan and launch the back-test.
