| 2025 Q4 | Jan 27, 2026 | Diamond Hill Mid Cap | 3.7% | 13.5% | CHKP, CIEN, CIVI, CUBE, GIS, HII, LEA, POST, VRSN, WCC, WIX, WLK, ZTS | AI, defense, healthcare, industrials, materials, mid cap, technology, value | AI-related spending continued to be a primary driver in equity markets throughout 2025, with many top-performing portfolio positions benefiting from ongoing AI-spending buildout across industrials, materials and information technology. However, the managers note increased investor scrutiny around AI developments and market bubble discussions in December. Data center business growth was a significant driver for portfolio holdings, with WESCO International's data center business reaching nearly 20% of total revenue and driving better-than-expected organic growth. The theme reflects the ongoing infrastructure buildout supporting AI and cloud computing demand. Defense spending opportunities emerged through Huntington Ingalls Industries, which benefited from strong Navy shipbuilding demand, new frigate contract awards, and discussion of potential Trump-class battleship opportunities. The company showed improving execution as labor challenges eased. | View | |

However, some holdings like Ciena benefited from hyperscaler and AI-related demand optimism. The managers express caution about AI bubble concerns emerging in December. WESCO International's data center business reached nearly 20% of total revenue and drove better-than-expected organic growth. The rapid expansion of this segment was a key contributor to the company's outperformance during the quarter. Huntington Ingalls Industries benefited from strong execution, new frigate contract awards, and discussion of a potential Trump-class battleship. Booz Allen Hamilton faced pressure from Department of Government Efficiency initiatives but remains well-positioned given differentiated technology capabilities and sustained government demand. The portfolio includes exposure to various real estate segments including self-storage (CubeSmart facing occupancy pressures), wireless tower infrastructure (SBA Communications), life sciences real estate (Alexandria Real Estate), and single-family rentals (Invitation Homes). The sector faces headwinds from higher interest rates and housing market challenges. | INVH ARE BAH SBAC CUBE GTES HII WCC CIEN ZTS HII |
