Giverny Capital’s Q2 2026 letter cites weak sentiment for IBP amid a 15.2% S&P 500 gain and momentum-driven tech rally.
Installed Building Products (IBP) underperformed in Q2 2026 as market sentiment shifted toward high-growth, AI-driven stocks. Giverny Capital’s model portfolio returned 13.7%, trailing the S&P 500’s 15.2% gain for the quarter. Year-to-date, the portfolio rose 5.89%, half the index’s 10.21% advance.
The divergence reflects broader market anomalies, with 210 S&P 500 stocks declining despite the index’s strong first-half performance. Investors favored momentum plays, particularly tech giants leveraging AI optimism, while traditional sectors like construction lagged. Giverny Capital noted concerns over sustainability, citing reliance on speculative “moonshot” investments.
The firm continues to advocate for a balanced approach, combining emerging tech leaders with established earnings compounders. IBP, a residential and commercial insulation installer, was highlighted as a laggard in the quarter.
