QuantumScape Plummets 7.69 as $550M Volume Ranks 190th in U.S. Liquidity Amid Commercialization Doubts

On September 24, 2025, QuantumScape (QS) closed with a 7.69% decline, marking its most significant single-day drop since the stock's market debut. The company's $550 million trading volume placed it at the 190th rank among U.S. equities by liquidity. The selloff coincided with renewed scrutiny over its battery technology commercialization timeline, as investors recalibrated expectations for regulatory hurdles and production scalability challenges highlighted in recent technical assessments.

Analysts noted that the decline was driven by sector-wide risk-off sentiment following a surprise commodities market correction, rather than QuantumScape-specific news. The stock's volatility underscored market sensitivity to broader energy transition themes, with institutional investors rotating capital toward more established energy storage solutions. Short-term traders capitalized on the move, with options data showing a 43% increase in bearish put options relative to average volumes.

To run this back-test accurately I need to pin down a few practical details that weren’t specified: 1. Equity universe • Should we look at all U.S. common stocks listed on NYSE / NASDAQ / AMEX, or a different universe (e.g., only S&P 1500 constituents)? 2. Ranking & trade timing • Do we form the “top-500-by-volume” list using each day’s close data, then open the position at next day’s open and exit at that day’s close (1-day holding period)? • If you prefer “buy at today’s close, sell at tomorrow’s close” let me know. 3. Weighting & capital allocation • Equal-weight across the 500 names is the usual assumption. Any different scheme? 4. Transaction costs / slippage • Default to zero unless you’d like to embed a per-trade cost. If the above defaults (U.S. common stocks; rank on close-t, buy next-day open, sell next-day close; equal weight; zero costs) match your intent, please confirm and I’ll start the data pull and back-testing. Otherwise just let me know your preferred settings.
