Is Ameren Stock Underperforming the S&P 500?

Ameren Corporation (AEE), headquartered in St. Louis, Missouri, is an energy utility serving customers across Illinois and Missouri. With a market capitalization of $28.8 billion, the company provides electric and natural gas services, generates and distributes power, and develops transmission infrastructure to improve grid reliability and support growing energy demand.

Companies valued between $10 billion and $200 billion are generally classified as “large cap stocks,” and Ameren comfortably fits this category. Its substantial market cap reflects its size, influence, and established presence in the regulated electric utilities industry. Ameren’s strength comes from its regulated utility model, which supports relatively predictable revenue and cash flows. Its diversified electricity and natural gas operations, extensive infrastructure, renewable energy investments, and focus on grid modernization provide a broad foundation, while strong workforce management supports operational reliability and efficiency.

Despite these strengths, AEE stock is currently 12.2% below its 52-week high of $118.32, reached on June 26. Over the past three months, AEE declined 4.6%, compared with the S&P 500’s ($SPX) 2.9% gain during the same time frame.

Shares of Ameren Corporation have gained 4.1% year-to-date and 5% over the past 52 weeks, trailing the S&P 500’s 11.6% YTD surge and 15.7% return over the past year.

AEE’s chart has weakened in recent months, with the stock falling below the 50-day moving average in late July and the 200-day average by late August, signaling growing bearish momentum.

Ameren’s stock performance has been a mixed bag, which makes more sense when you look at what is happening underneath the headline numbers. Higher operations and maintenance costs, softer electric retail sales due to milder weather, and rising interest expense have weighed on the business.

The company’s second-quarter results on July 30 reflected that uneven picture.  Revenue came in at $2.09 billion, below Wall Street’s expectations, but the bottom line told a different story. Net income climbed 14.2% year over year to $314 million, while EPS rose 11.9% to $1.13, topping consensus estimate.

The stock has also faced pressure amid concerns over Ameren’s rising capital spending and debt burden. Long-term debt reached $19.06 billion as of June 30, 2026, up from $18.21 billion at the end of 2025, while capital expenditures climbed to $2.65 billion from $2.13 billion. That combination has kept investors cautious, as the company continues to invest heavily in its infrastructure while taking on more debt to fund that spending.

Within the competitive regulated electric utilities industry, rival NextEra Energy, Inc. (NEE) has trailed AEE on a year-to-date basis, gaining 1.3% during the period. However, NEE has shown greater resilience over the past 52 weeks, returning 15.6% compared with AEE’s performance.

Wall Street analysts are somewhat bullish on AEE’s prospects. The stock carries a consensus “Moderate Buy” rating from the 16 analysts covering it. The mean price target of $120.50 implies 16% upside potential from current levels.
