On September 26, 2025,

(RMD) traded with a volume of $200 million, ranking 498th in market activity. The stock closed up 1.11% for the session, outperforming broader market trends amid mixed sectoral performance.

Analysts attributed the upward movement to renewed investor confidence in the company’s respiratory care segment following recent operational updates. While no direct earnings catalysts were cited, strategic positioning in the sleep apnea treatment market appears to have reinforced short-term momentum. The volume level, though below average for the stock, suggests selective buying pressure from institutional participants.

Backtesting parameters for evaluating volume-driven strategies require clarification on key variables: stock universe (U.S.-listed only or S&P 1500 subset), execution rules (previous day volume ranking with next-day open entry), and transaction cost assumptions. Constraints such as liquidity filters or session-specific trading limitations also need definition before running the test. Finalizing these parameters will ensure robustness in assessing the strategy's historical viability.
