Quantum Computing’s Modest Price Gain Overshadowed by 20.37% Volume Drop Ranking 112th in Trading Activity

On September 24, 2025, Quantum Computing (QUBT) saw a 0.02% rise with a trading volume of $0.84 billion, representing a 20.37% decline from the previous day’s activity. The stock ranked 112th in volume among listed equities, reflecting subdued investor engagement despite the modest price gain.

Market participants observed limited catalysts directly influencing QUBT’s performance. The firm’s recent technical roadmap updates and R&D disclosures remain the primary focus for analysts, though no new product launches or partnerships were announced to drive immediate momentum. Institutional activity remained neutral, with no significant block trades reported in the session.

For the back-test framework, key parameters require clarification to ensure methodological rigor. The market universe must specify whether the top-500-by-volume list includes all U.S.-listed equities on NYSE and NASDAQ or a narrower subset. Weighting conventions—such as equal weighting versus dollar-volume-based allocation—alongside daily rebalancing protocols need confirmation. Trading frictions, including transaction costs and slippage assumptions, must also be defined. Lastly, the data scope must address whether delisted tickers are included to mitigate survivorship bias.
