Cummins Shares Tumble 3.19% as $290M Volume Ranks 449th in U.S. Markets Amid Supply Chain Woes and Hydrogen Delays
Cummins Inc. (CMI) closed 10/10/2025 at a 3.19% decline, with a trading volume of $290 million, ranking 449th in U.S. equity volume. The selloff came amid mixed signals from its clean energy initiatives and supply chain challenges. Analysts noted short-term technical weakness as the stock tested key support levels following a broader sector correction in industrial equipment manufacturers.
Recent developments highlighted Cummins’ strategic pivot toward hydrogen-powered engine technology, with production timelines delayed by 6-12 months due to supplier bottlenecks. While the company reaffirmed long-term EBIT margin expansion targets of 18-20% by 2028, near-term concerns over inventory management and cash conversion cycles have pressured investor sentiment. Short interest rose 12% in the past fortnight, indicating growing bearish positioning.
To run this back-test accurately, I need to pin down a few practical details: 1) Universe—Should we screen all U.S. listed common stocks (NYSE + NASDAQ), or another market/universe? 2) Execution logic—Rank date: use today’s trading-volume ranking calculated on the close, then enter at the same close and exit the next day’s close (close-to-close return), or do you prefer open-to-open / close-to-open, etc.? 3) Weighting: equal-weight each of the 500 names, or volume-weight / market-cap-weight? 4) Cash management and friction—Commissions or transaction fees? Slippage assumptions (if any)? 5) Output—Key metrics you care about beyond cumulative return (e.g., annualized return, max draw-down, Sharpe)? Let me know your preferences (or confirm the default assumptions below and I’ll start the run): Default assumptions I would use unless instructed otherwise: • Universe: all U.S. common stocks. • Enter at each day’s close, exit next day’s close. • Equal-weight portfolio of the 500 highest-volume names. • No commissions/slippage. • Report cumulative & annualized return, volatility, Sharpe, and max draw-down. Please confirm or adjust any of the above so I can proceed with the back-test.
