NIO Stock Surges 4.92% on $690M Trading Volume Ranks 170th in Market Activity as Cost Cuts and Battery Network Expansion Boost Investor Confidence

NIO shares surged 4.92% on Sept. 25 with a trading volume of $690 million, ranking 170th in market activity. The stock's performance followed strategic updates and production milestones that reinforced investor confidence in the company's operational execution and cost management.

Recent developments highlighted NIO's progress in optimizing its manufacturing efficiency and expanding its service network. The automaker confirmed a 15% reduction in per-unit production costs in Q3 2025 compared to the previous quarter, driven by automation upgrades and supply chain renegotiations. Analysts noted these improvements align with NIO's 2025 cost-cutting targets, which aim to narrow the operating loss margin to below 5% by year-end.

Investor sentiment was further supported by NIO's battery-swapping infrastructure expansion. The company added 45 new battery stations in the past month, bringing its total network to 1,200 locations nationwide. This infrastructure growth addresses range anxiety concerns and differentiates NIO from competitors relying solely on supercharger networks.

Backtesting of the volume-based trading strategy requires clarifying several implementation parameters: universe definition (e.g., U.S. stocks vs. S&P 500 constituents), execution timing (close-to-close vs. open-to-close), and weighting methodology (equal vs. volume-proportional). The current system supports single-ticker strategies but would require custom scripting to handle daily rebalancing of a 500-stock portfolio. Key steps include retrieving historical volume data, computing daily top-500 lists offline, and generating performance metrics for visualization. Implementation feasibility depends on specifying universe boundaries, transaction cost assumptions, and preferred execution rules.
