Artisan Partners, an investment management company, released its second-quarter 2026 investor letter for its “Artisan Small Cap Fund”. A copy of the letter can be downloaded here. The fund reported strong absolute returns and modestly outperformed the Russell 2000® Growth Index, which gained 25.7%. Global equities rebounded as resilient US growth, moderating inflation, strong earnings and continued AI investment outweighed delayed rate cuts, rising bond yields and geopolitical uncertainty. Investor Class: ARTSX, Advisor Class: APDSX, and Institutional Class: APHSX returned 26.02%, 26.05%, and 26.11%, respectively, in the second quarter, compared to a 25.71% return for the index. Market leadership favored loss-making, highly leveraged companies, creating a difficult environment for quality-focused active managers. Health care was the strongest relative contributor, while energy, materials, financials and real estate also helped. Technology, industrials and consumer discretionary detracted, partly because the fund did not own oversized index contributors. Software holdings also weakened despite strong fundamentals. The fund remains positive on small-cap opportunities, AI infrastructure and health care, but has reduced software exposure and is staying selective as valuations rise and competitive risks increase.

Artisan Small Cap Fund stated the following regarding Installed Building Products, Inc. (NYSE:IBP) in its Q2 2026 investor letter:
“Installed Building Products, Inc. (NYSE:IBP) is the second-largest insulation installer in the US and manages the full installation process—from material procurement to scheduling, logistics and installation. Recent results were weaker than expected, as softer residential demand, weather-related disruptions and cost inflation lowered margins despite continued strength in commercial construction. While management highlighted improving residential trends and a growing commercial backlog, the quarter raised questions about the pace of the company’s profit cycle. The residential business took a step backward after several quarters of better-than-expected execution, while tougher comparisons in commercial suggest the overall profit cycle may take longer to inflect upward. We reduced the position back to the Garden,as we believe it may take several quarters for the profit cycle to regain momentum.”
