D-Wave Quantum Plummets 1.7% as Regulatory Scrutiny and Rival Partnership Drive Down 184th in $540M Daily Trading Volume

D-Wave Quantum (QBTS) fell 1.70% on August 20, 2025, with a trading volume of $540 million, ranking 184th in market activity for the day. The stock's performance was influenced by sector-specific dynamics amid broader market volatility.

Analysts noted that recent regulatory scrutiny on quantum computing firms weighed on investor sentiment. A U.S. Senate hearing highlighted concerns over data security protocols, prompting short-term sell-offs across the sub-sector. Additionally, a key partnership announcement between a rival quantum firm and a European research institute created relative pressure on D-Wave's valuation multiples.

Market participants observed that the stock's liquidity profile showed mixed signals. While institutional buying activity increased in the morning session, heavy options expiration activity in the afternoon amplified downside momentum. The stock's 20-day average volume remained stable, suggesting the decline was more reflective of tactical positioning rather than fundamental concerns.

The strategy of buying the top 500 stocks by daily trading volume and holding them for one day from 2022 to present delivered 0.98% average daily returns, accumulating 31.52% total returns over 365 days. This demonstrates the strategy's ability to capture short-term momentum while underscoring inherent risks from market timing and volatility exposure.
