Deere Slumps 1.77% on 81.6% Volume Surge, Ranks 142nd as Macro Risks and Management Shakeup Weigh

On September 30, 2025, Deere & Company (DE) closed with a 1.77% decline, trading on $0.89 billion in volume—a 81.6% surge from the prior day—ranking 142nd among U.S. equities by liquidity. The stock’s performance contrasted with broader market resilience amid mixed economic signals.

Recent developments highlighted Deere’s exposure to macroeconomic uncertainties. Analysts noted that rising interest rates and volatile agricultural commodity prices continue to pressure the firm’s long-term equipment financing business. While the company’s recent earnings report showed stable core operations, forward-looking guidance remained cautious due to global supply chain disruptions.

Market participants observed heightened short-term volatility following a regulatory filing disclosing management reshuffling in the agricultural division. Though operational details were limited, the move sparked speculation about strategic realignments. However, the company emphasized no material impact on near-term financial commitments.

The current back-testing engine that I can invoke is designed for a single security at a time. Your idea—rebalance every day into the 500 most-traded stocks—requires a multi-asset portfolio back-test, which is outside the scope of the available automated tools. Two ways we can proceed: 1. Narrow the request to one security (e.g., an ETF or index constituent) and test a simpler entry/exit rule. 2. Export the raw daily volume rankings (outside this chat) and run a cross-sectional back-test in external software. Please let me know which path you’d like to take, or if you have a different adjustment in mind.
