Diamond Hill Capital, a First Eagle Investment Management company, disclosed a new position in Ameren Corporation (NYSE: AEE) as part of its Q3 2026 Large Cap Strategy investor letter.

The strategy returned 3.18% net of fees during the third quarter, outperforming the Russell 1000 Value Index, which posted a 2.61% return over the same period.

Key positive contributors to performance included stock selection in information technology, an underweight position in utilities, and an overweight in energy during the quarter.

Detractors from performance were found in industrials, health care, and consumer staples, partially offsetting the gains achieved in other sectors.

Looking ahead, Diamond Hill anticipates below-average returns driven by elevated equity market valuations, though the firm notes that attractive bottom-up investment opportunities remain available.

Ameren Corporation is a public utility holding company that provides electric power and natural gas to millions of customers across its service territories.

Shares of Ameren closed at $106.08 on October 16, 2026, giving the company a market capitalization of approximately $29.37 billion at that time.

The stock has gained 6.23% year-to-date and has traded within a 52-week range of $96.57 to $118.32, reflecting steady investor interest in the regulated utility sector.

Diamond Hill’s Q3 2026 investor letter stated: “Ameren Corporation (NYSE: AEE), a regulated electric and gas utility, was added to the portfolio given its combination of steady growth, a strong balance sheet and supportive regulatory environment. We believe its attractive rate base growth outlook should also support long-term growth.”

According to available data, 46 hedge fund portfolios held positions in Ameren at the end of the second quarter of 2026, up slightly from 45 portfolios in the prior quarter.

Software and legacy technology stocks outperformed during Q3 2026, while certain AI-related stocks that had previously boosted broader index performance lagged during the period.

The addition of Ameren to Diamond Hill’s Large Cap Strategy signals renewed institutional appetite for regulated utilities offering predictable cash flows and visible earnings growth pathways.
