Cencora's 45.56% Trading Volume Surge Propels It to 303rd in Market Activity

On October 10, 2025, Cencora (COR) saw a surge in trading activity with $0.42 billion in volume, a 45.56% increase from the previous day, ranking it 303rd in market activity. The stock closed up 1.24% for the session.

Recent developments suggest heightened investor interest in Cencora’s operational strategies. A strategic partnership announcement with a major pharmaceutical distributor highlighted potential revenue diversification. Analysts noted the move could strengthen supply chain efficiencies, aligning with industry trends toward cost optimization in healthcare logistics.

Market participants are also tracking Cencora’s recent capital allocation decisions. The company announced a $150 million investment in automation technologies for its fulfillment network. While the expenditure may temporarily impact short-term margins, the long-term goal of reducing operational costs has been well-received by sector watchers.

To run this back-test accurately I need to pin down a few practical details that aren’t specified yet. Once those are clear I can assemble the data set and run the engine. Universe • Should we scan all U.S. common stocks (NYSE + NASDAQ + AMEX) each day, or a different universe (e.g., S&P 1500, Russell 3000, etc.)? Entry & exit prices • Open trade at that day’s close and exit at next day’s close (typical “hold 1 day” definition)? • Or open at next day’s open and exit at next day’s close? Weighting & capital allocation • Equal-weight each of the 500 names? (default) • Any leverage or position limit? Transaction cost assumptions • Use zero cost (default) or specify $/share or bps per trade? Let me know your preferences (or just confirm the defaults above) and I’ll proceed with the back-test from 2022-01-03 through today (2025-10-10).
