About DIAMX

Diamond Hill Long-Short Fund Investor Share is a mutual fund that employs a long-short equity strategy, aiming to deliver long-term capital appreciation by holding both long and short positions in U.S. equities. Managed by Diamond Hill Capital Management, the fund selects long positions in companies it believes are undervalued and short positions in those deemed overvalued, based on its intrinsic value assessment. The investment approach treats each holding as a partial ownership interest, seeking long investments at a discount and short exposures at a premium to intrinsic value, with the expectation that market and intrinsic values will converge over time. This fund typically maintains 40–60 long positions and 25–50 short positions, with long positions generally comprising 80–100% of net assets and short positions 10–40%. The strategy is long-biased but flexible, offering some market downside protection through its short book. The fund invests across all market capitalizations, providing broad exposure to U.S. equity markets. Its focus on valuation-driven stock selection and risk management makes it significant for investors seeking a differentiated equity approach, and it occupies a unique role in the market by offering potential diversification benefits relative to traditional long-only equity funds.
