BioAffinity (BIAF) surged 55.13% on Sept. 26, 2025, with a trading volume of $600 million, marking a 39,273.86% increase from the previous day. The stock ranked 149th in volume among U.S.-listed equities, reflecting an anomalous spike in market activity.
The abrupt price movement followed a strategic partnership announcement with a biotech firm specializing in AI-driven drug discovery. The collaboration aims to accelerate development of novel therapeutics targeting neurodegenerative diseases, a sector showing heightened investor interest amid recent regulatory tailwinds. No material earnings updates or clinical trial results were disclosed in the period.
Analysts noted the trade appears to have been triggered by speculative positioning rather than fundamental catalysts. Short-term technical indicators suggest heightened volatility, with the stock testing key resistance levels. Institutional activity remains muted, with retail traders dominating the volume surge through after-hours trading platforms.
To run a precise back-test I’ll need a bit more detail about the universe and execution rules: 1. Market / universe • All U.S.–listed common stocks? • A narrower list such as the S&P 500, Russell 3000, or another region? 2. Trade timing • Enter at today’s close and exit at tomorrow’s close? • Or enter at tomorrow’s open and exit at tomorrow’s close? 3. Weighting • Equal-weight each of the 500 names? • Weight by dollar volume or something else? Once I have this information I can generate the data-retrieval plan and run the back-test.
