Dexcom (DXCM) closed higher by 0.54% on October 2, 2025, with a trading volume of $0.32 billion, reflecting a 35.23% decline from the previous day's activity. The stock ranked 370th in trading volume among listed equities during the session.

Recent market sentiment appears to have been influenced by broader healthcare sector dynamics, with investors focusing on regulatory updates and product pipeline progress. Analysts noted that Dexcom’s performance aligns with sector trends, though its relatively muted volume suggests limited short-term speculative interest compared to peers.

For backtesting purposes, key parameters require clarification to ensure methodological accuracy: 1. The universe of stocks must specify the exchange(s) for sourcing the "top-500-by-volume" list daily. 2. Signal construction timing should define whether volume data is based on prior-day full-volume (entering at the next open) or intraday data (entering at the close). 3. Execution price assumptions need to clarify whether trades occur at the next open/close or same-day close. 4. Position weighting must be determined—equal-weight or volume-weighted schemes. These details are critical for generating actionable buy/sell signals and conducting a reliable backtest from January 1, 2022, to the present.
