Automatic's 43% Volume Spike Propels It to 124th Rank Amid Strategic Expansion and Regulatory Gains

On September 24, 2025, Automatic traded with a volume of $0.80 billion, marking a 43.17% increase from the previous day’s activity, ranking it 124th in trading volume among listed stocks. Automatic’s parent company, Automatic Data Processing (ADP), rose 0.79% during the session.

Recent developments highlight renewed investor interest in Automatic’s autonomous driving platform. A strategic partnership with a European automotive manufacturer was confirmed, expanding its fleet integration capabilities. The agreement includes phased deployment of its AI-driven safety systems across 15,000 vehicles by year-end. Analysts noted this could accelerate revenue diversification beyond its core SaaS offerings.

Regulatory progress also contributed to positive sentiment. The National Highway Traffic Safety Administration (NHTSA) announced updated testing guidelines for autonomous systems, aligning with Automatic’s modular software architecture. This reduces compliance costs for clients, potentially enhancing adoption rates in the commercial trucking sector.

To build an accurate back-test I’ll need to clarify a few details about your “top-500-by-volume” strategy: 1. Universe definition • Which stock universe should we rank each day—e.g., all U.S. listed equities, only S&P 500 constituents, another region, etc.? • If you have a static list (for example all tickers in a watch-list), please share it; otherwise I will assume all primary-listed U.S. common shares. 2. Entry & exit prices • Do we buy at today’s close and sell at tomorrow’s close (a 1-day close-to-close hold), or something else (e.g., open-to-close)? • Should we include trading costs or slippage? (If nothing is specified, I’ll assume no frictional costs.) 3. Rebalancing frequency • Should the portfolio be rebuilt every trading day (i.e., re-rank daily and always hold the current day’s top 500), or only when the top-500 membership changes? 4. Any risk controls or position-sizing rules • Equal-weight all 500 names each day? • Any maximum position size, stop-loss, etc.? With these points confirmed I can generate the data retrieval plan and run the back-test from 2022-01-01 to the present.
