Ameren Corporation (AEE) closed at $104.91 on September 12, 2026, down 0.05% over the prior 24-hour period. The utility company's market capitalization stood at $29.05 billion.
The slight daily dip extends a more pronounced pullback over recent weeks. AEE has fallen 1.47% over the past seven days and is down 4.00% over the trailing 30-day period, reflecting sustained selling pressure on the stock.
Ameren operates as a regulated utility serving customers in Missouri and Illinois. Like many rate-regulated peers, its share price is sensitive to interest rate expectations and broader sector sentiment, though the data provided does not specify a particular catalyst for the recent moves.
With the 30-day decline now at 4.00%, AEE has underperformed over the near term, though its price above $104 per share keeps it within a range consistent with its multi-billion-dollar market valuation.
