QuantumScape's $1.17B Volume Ranks 104th as Stock Slips 1.93% Amid Solid-State Battery Hurdles

On October 10, 2025, QuantumScape (QS) traded with a volume of $1.17 billion, ranking 104th among U.S. stocks by daily trading activity. The stock closed down 1.93%, reflecting renewed investor caution following recent developments in the solid-state battery sector.

Recent updates highlighted potential delays in the company’s production timelines, with analysts noting unresolved technical challenges in scaling its proprietary battery technology for mass-market adoption. Reports also underscored regulatory scrutiny over safety protocols, which have historically impacted investor sentiment in the energy storage industry. While no direct earnings or partnership announcements were disclosed, the broader market’s sensitivity to sector-specific risks appears to have pressured QuantumScape’s valuation.

Back-test parameters require clarification to assess performance accurately. Key considerations include the exchange scope (e.g., NYSE/Nasdaq), portfolio weighting methodology (equal-weighted or volume-proportional), and assumptions about transaction costs. A benchmark comparison, such as the S&P 500, would further contextualize results. Once defined, the test can evaluate daily-volume rankings and trading signals from January 1, 2022, to October 10, 2025.
