Ameren Corporation (AEE) closed at $106.27 on September 10, 2026, declining 0.45% over the prior 24 hours. The St. Louis-based utility's market capitalization stood at $29.48 billion at the close of trading.
Looking at a broader window, AEE has posted a modest gain of 0.34% over the past seven days, suggesting the single-session dip represents a minor pullback within an otherwise steady short-term trend. The 30-day performance tells a similarly quiet story, with shares down just 0.68% over that span.
The narrow range of movement across all three time periods reflects the low-volatility trading profile typically associated with regulated utility stocks. AEE's price action over the past month has remained well within a tight band relative to its current level.
With a market capitalization just under $29.5 billion, Ameren remains one of the larger publicly traded utilities in the United States. Thursday's session offered little in the way of dramatic directional movement, as the stock continued to trade in a measured range.
