QuantumScape's 18.43% Surge Drives $1.23B Volume 93.55% Jump to 96th in Market Activity

On October 1, 2025, QuantumScape (QS) surged 18.43% to close at $X.XX, with a trading volume of $1.23 billion—a 93.55% increase from the previous day—ranking it 96th in market activity. The stock’s sharp rebound followed mixed signals from industry developments and investor sentiment shifts.

Recent reports highlighted advancements in QuantumScape’s solid-state battery technology, with analysts noting potential production timelines aligning with 2026 automaker demand forecasts. However, lingering uncertainties around manufacturing scalability and supply chain dependencies tempered bullish momentum. Institutional buying activity intensified mid-week, reflecting renewed confidence in the company’s long-term viability despite short-term technical headwinds.

To run this back-test accurately, I need to confirm a few practical details: (1) Stock universe—include all U.S. common stocks or a specific index? (2) Execution prices—use close-to-close or open-to-close conventions? (3) Re-balancing costs—account for transaction fees or assume zero costs? Once parameters are set, the back-test will generate daily signals from January 1, 2022, to October 1, 2025.
