NIO's Trading Volume Plummets 46.31% to $440M, Ranking 293rd in U.S. Markets Amid Cost-Optimization Push

On October 1, 2025, NIO (NIO) closed with a 0.39% gain, marking a modest rebound in trading volume despite a 46.31% decline in daily turnover to $440 million, ranking the stock 293rd in trading activity across U.S. markets. The limited liquidity suggests mixed investor sentiment amid evolving market conditions.

Recent developments indicate a focus on operational adjustments and strategic positioning. Management emphasized cost-optimization initiatives and supply chain efficiency, signaling a shift toward profitability-driven strategies. Analysts noted that these measures could influence short-term investor confidence, though broader market volatility remains a key variable.

To run this back-test rigorously I’ll need a little more detail, because the platform treats each “ticker” separately and I have to translate your “top-500-by-volume” idea into something it can process. Key points to confirm: 1. Trading universe • Do you want to draw from all listed U.S. equities, from the S&P 500 constituents, or another universe? 2. Portfolio construction • Equal-weight each day across the 500 chosen names? (default) • Any transaction-cost assumption? (e.g., 5 bp per trade) 3. Practical constraints • The current engine runs one ticker at a time; for a multi-stock basket we’d create a synthetic index of the daily “Top-500” portfolio and back-test that index’s returns. I can generate that synthetic index for you, but please confirm you’re comfortable with this approach. Let me know your preference (or feel free just to approve the default assumptions above) and I’ll build the test accordingly.
