Could Legence (LGN) Be a Major Winner From the AI Data Center Construction Boom?

Baron Capital , an investment management company, released its Q2 2026 investor letter for the "Baron Small Cap Fund." Baron Small Cap Fund gained 12.57% (Institutional Shares) in the second quarter, trailing the Russell 2000 Growth Index's 25.71% return. A copy of the letter can be downloaded here . U.S. equities rebounded sharply after March's selloff related to the U.S.-Iran conflict, with AI infrastructure, semiconductors, and other technology stocks driving much of the market's gains. Small caps also outperformed large caps, although performance remained concentrated in high-Beta and Momentum stocks, areas where the Fund has historically had less exposure. The Fund benefited from several AI-related and industrial holdings, but software and services stocks remained pressured by concerns that AI could disrupt their businesses. Looking ahead, management believes broader market participation, attractive small-cap valuations, improving industrial growth, and stronger earnings could support future returns despite continued uncertainty around oil prices, inflation, and interest rates.
