Lucid Group Stock Rises 2.78% on 33.7% Volume Jump Hits 403rd in US Trading Activity

On October 3, 2025, Lucid Group (LCID) rose 2.78% to close trading with a volume of $270 million, marking a 33.7% increase from the previous day. The stock ranked 403rd in trading activity among U.S.-listed equities.

Recent developments suggest heightened investor interest in the electric vehicle manufacturer, driven by strategic production adjustments and supply chain optimization efforts. Management has emphasized cost-reduction initiatives across battery production and logistics, with preliminary data indicating improved operational efficiency in Q3 2025.

Analysts highlight that the stock's volume surge aligns with broader market speculation about potential partnerships in the EV charging infrastructure sector. While no official announcements have been made, recent supply chain contracts show expanded capacity agreements with key battery suppliers.

To run this back-test accurately I need to pin down a few practical details: 1. Stock universe • Should we limit the selection to U.S. listed equities (NYSE + NASDAQ) or another market? • Do you want to exclude ETFs, ADRs, penny stocks, etc.? 2. Portfolio construction • Equal-weight the 500 names each day, or weight by something else (e.g., volume-weighted)? • Rebalance every trading day and fully exit the positions at the next day’s close? 3. Trading frictions • Assume zero commissions/slippage, or apply a transaction-cost estimate? • Any liquidity filter beyond “top-500 by volume” (e.g., minimum price)? 4. Benchmark (optional) • Compare against SPY or another index? Once those points are settled I’ll pull the daily volume ranks, generate the daily trading signals, and run the back-test from 2022-01-03 (first trading day of 2022) through the latest available date.
