On September 24, 2025, Copart (CPRT) recorded a trading volume of $0.29 billion, marking a 34.83% decline compared to the previous day’s activity. The stock closed with a 0.24% gain, placing it in the 344th position for trading volume among listed equities.

Recent developments highlight Copart’s operational focus amid evolving market dynamics. The company has emphasized optimizing its vehicle inventory management systems to enhance auction efficiency, a strategic move aimed at maintaining margins in a competitive sector. Analysts note that Copart’s ability to streamline logistics and reduce turnaround times for salvaged vehicles remains a key differentiator, particularly as demand for cost-effective vehicle disposal solutions stabilizes.

Market participants are closely monitoring Copart’s capacity to adapt to shifting regulatory environments, especially in states with stringent vehicle recycling mandates. While the company has not disclosed specific earnings guidance, its recent infrastructure investments signal a long-term commitment to infrastructure resilience, which could influence investor sentiment in the near term.

To run this back-test accurately I need to pin down a few practical details that aren’t fully specified yet: 1. Which market / universe should the “top 500 stocks” be drawn from? • All U.S. listed equities (NYSE + Nasdaq)? • A specific index membership (e.g. Russell 3000, S&P Composite 1500, etc.)? 2. Entry and exit pricing: • Buy at today’s close and sell at tomorrow’s close (typical “hold 1 trading day” rule)? • Or buy at next day’s open and sell at the same day’s close? 3. Weighting scheme inside the daily 500-stock basket: • Equal-weight each name? • Volume-weight or market-cap weight? 4. Any assumptions for transaction costs, slippage, or liquidity filters besides the volume rule? (If none, I’ll model a frictionless portfolio.) Once these items are set I can generate the trading signals, run the back-test from 2022-01-03 (first trading day of 2022) through today, and report the performance statistics.
