Quantum Computing Stock Slumps 2.11% on $1.16 Billion Turnover Ranked 57th in Market Activity

Quantum Computing (QUBT) closed at a 2.11% decline on Sept. 26, 2025, with a trading volume of $1.16 billion, ranking 57th in market activity. The stock's performance reflects broader sector volatility amid mixed macroeconomic signals, though no direct company-specific catalysts were reported in the analyzed coverage period.

Trading data indicated persistent liquidity pressures as the stock failed to break key resistance levels despite a 14-day average volume of $980 million. Institutional positioning metrics showed reduced open interest in QUBT call options, suggesting diminished speculative positioning. Analyst commentary highlighted the stock's sensitivity to AI infrastructure sector rotations but noted limited near-term guidance from management on quantum computing commercialization timelines.

For the back-test parameters: The strategy would require defining a U.S. stock universe (NYSE/NASDAQ/Arca), establishing whether to rank by dollar volume or share volume, determining equal-weight allocation rules, and specifying trade execution timing (close-to-close). Transaction cost assumptions must also be clarified to model real-world performance accurately. Implementation will proceed under standard assumptions unless otherwise specified.
