Entergy’s $0.36B Volume Jumps 66% Amid Regulatory Uncertainty Hits 347th Rank

On October 10, 2025, Entergy (ETR) traded with a volume of $0.36 billion, marking a 66.77% increase from the previous day and ranking 347th in terms of trading activity across the stock market. The utility company’s shares closed 0.38% lower, reflecting investor caution ahead of key regulatory developments.

Recent market activity suggests heightened sensitivity to sector-specific dynamics. A proposed regulatory overhaul in the energy sector, which could impact utility rate-setting mechanisms, has prompted mixed investor sentiment. Analysts note that Entergy’s exposure to southeastern U.S. markets—where recent infrastructure spending plans remain uncertain—may amplify short-term volatility. The stock’s volume surge indicates active position adjustments, though price action remains constrained by broader market risk-off tendencies.

To run this back-test accurately, additional parameters are required: (1) the universe of 500 stocks (e.g., U.S. equities on NYSE/NASDAQ/AMEX), (2) volume ranking criteria (share count or dollar volume), (3) trade execution timing (close-to-close, open-to-open, etc.), and (4) transaction cost assumptions. These details will ensure the back-test aligns with the specific market conditions observed on October 10, 2025.
