Quantum Computing Tumbles 10.81 as Supply Chain Woes and EU Regulation Hit 1.05B-Dollar Trade Ranking 119th in Liquidity

On October 10, 2025, Quantum Computing (QUBT) closed with a 10.81% decline, trading with a volume of $1.05 billion, ranking 119th in market liquidity. The stock’s sharp drop raised questions about sector-specific pressures and investor sentiment shifts in the quantum technology space.

Recent developments highlighted include a strategic pivot by Quantum to delay its next-gen quantum processor roadmap by 12 months, citing supply chain bottlenecks for specialized components. Analysts noted the delay could impact short-term revenue visibility for the company, though the long-term product vision remains intact. Additionally, regulatory scrutiny intensified in the quantum computing sector, with a proposed EU directive aiming to standardize data security protocols, creating near-term uncertainty for firms like Quantum.

Market participants observed increased short-term volatility linked to a 10% sell-off in Quantum’s institutional holdings, as reported by third-party tracking platforms. While the company has not disclosed specific institutional exits, the pattern aligns with broader market rotation into AI infrastructure stocks. Quantum’s liquidity profile, however, remained resilient, with its $1.05 billion daily turnover underscoring active trading interest despite the price drop.

I understand you’d like to study a daily-rebalanced “top-500-by-volume” portfolio, but I need to highlight two practical constraints in our current back-testing environment: (1) The strategy_backtest_engine can work with only one ticker at a time. (2) Our data-retrieval tools let us pull trading-volume or other indicators for a specific ticker, but they do not yet support cross-sectional ranking across the entire market universe in an automated way. Possible workarounds include narrowing the request to a single security or manually generating pre-ranked signals for import.
