Harbor Mid Cap Value Fund, subadvised by LSV Asset Management, delivered solid outperformance in the fourth quarter of 2025, with the Institutional Class returning 4.07% versus 1.42% for the Russell Midcap Value Index, benefiting from strength in value stocks as the Russell Midcap Growth Index declined 3.7% during the period. U.S. equities broadly advanced, with the S&P 500 Index rising 2.7% in the quarter and 17.9% for the full year, while mid-caps lagged, with the Russell Midcap Index up just 0.2% in Q4. For 2025, the Fund gained 15.95% (Institutional Class), outperforming the benchmark’s 11.05% return. Attribution data show a total quarterly excess return of 2.82%, largely from selection effects, underscoring the manager’s quantitative value discipline focused on fundamental undervaluation, improving momentum, and risk control. Looking ahead, management noted that while AI-driven large-cap leadership has elevated valuations in certain segments, mid- and small-cap value stocks continue to trade at more attractive multiples, positioning the Fund to capitalize on opportunities within economically sensitive and cash-generative businesses.
