Ducommun Incorporated's Missile Division Fuels Growth
In the first quarter of 2026, Diamond Hill Capital's Small Cap Strategy saw notable success, with Ducommun Incorporated (DCO) emerging as a key driver. The company's robust performance is primarily attributed to its thriving missile division, which accounts for a substantial portion of its defense revenue, directly benefiting from accelerated Pentagon expenditures. Additionally, Ducommun's strategic expansion into engineered products has bolstered its pricing power and enhanced profit margins, a feat traditional manufacturers often struggle to achieve. This strategic positioning allows Ducommun to broaden its market reach while simultaneously boosting profitability in an environment of increasing defense spending.
Diamond Hill Capital, a division of First Eagle Investment Management, released its investor letter for the initial quarter of 2026, detailing the performance of its Small Cap Strategy. Despite a strong start to 2026, small-cap stocks experienced a downturn later in the quarter due to escalating geopolitical tensions, particularly between the United States, Israel, and Iran. During this period, the Russell 2000 index posted a gain of 0.89%, outperforming the Russell 1000, which recorded a 4.18% decline. The energy sector led the market with a 38% increase, driven by a surge in oil prices amidst supply concerns. The Small Cap Strategy itself delivered a net return of 3.41%, surpassing the Russell 2000's performance. The fund's investment philosophy centers on identifying resilient businesses capable of navigating market volatility and capitalizing on emerging opportunities.

The investor letter from Diamond Hill Small Cap Strategy specifically highlighted Ducommun's role as a top performer. The letter emphasized that the company's missile franchise, contributing approximately 25% to its defense revenue, is directly benefiting from increased spending by the Pentagon. Furthermore, Ducommun's venture into engineered products has created significant pricing leverage and margin expansion, a strategic advantage that sets it apart from conventional manufacturers. This allows Ducommun to not only grow its core markets but also enhance profitability, especially in a period characterized by heightened defense spending. This strategic foresight and operational excellence position Ducommun for sustained growth and value creation.
