Ameren Corporation (AEE) closed at $101.29 on October 8, 2026, marking a decline of 0.37% over the prior 24 hours. The Missouri-based utility's market capitalization stood at $28.15 billion at the close of trading.
Despite the daily dip, AEE posted a gain of 1.88% over the trailing seven-day period, suggesting some near-term stabilization after recent selling pressure. The stock's weekly performance offered a modest counterpoint to a broader monthly trend.
Over the past 30 days, however, Ameren shares have shed 4.87%, reflecting a more sustained period of weakness for the regulated utility. The stock's current price of $101.29 places it well below where it traded a month ago.
Ameren operates as a regulated electric and gas utility serving customers across Missouri and Illinois. As a rate-regulated business, the company's shares are often sensitive to interest rate expectations and broader utility sector sentiment.
