On September 25, 2025,

(TMO) traded with a volume of $1.49 billion, representing a 32.07% increase from the previous day’s activity. The stock closed down 1.88%, ranking 50th in trading volume among listed equities. The surge in liquidity occurred amid mixed market conditions, though no direct catalysts were cited in available reports.

Analysts observed heightened short-term volatility linked to broader market positioning shifts. Institutional activity remained neutral, with no major portfolio rebalancing reported. The volume spike suggests increased speculative interest or hedging activity, though its directional impact on the stock remains ambiguous without concrete earnings or strategic updates.

To validate potential trading signals, a structured back-test requires clarification on key parameters. This includes defining the investment universe (e.g., S&P 1500 vs. broader exchanges), volume measurement criteria (dollar vs. share count), and execution timing (e.g., T-1 ranking with T-day entry). Transaction cost assumptions also need specification to ensure model accuracy. Finalizing these details will enable precise historical performance evaluation.
