Conestoga Capital Advisors, an asset management company, released its second-quarter 2026 investor letter. A copy of the letter can be downloaded here. The letter reports a positive market shift towards Small Caps, with the Russell 2000 Index achieving its best first half since 1991 and the Russell 2000 Growth Index up 25.7% in Q2, fueled by AI enthusiasm and semiconductor stocks. However, market leadership was uneven, mirroring the Tech Bubble, as high-beta stocks outperformed while high-quality companies lagged, impacting Conestoga’s quality-focused strategies. Management expressed confidence in long-term outcomes, noting that speculative leadership won’t last as monetary policy tightens and market breadth improves. The firm remains committed to high-quality growth businesses, expecting these to regain favor as leadership broadens. The Conestoga Small Cap Composite returned 14.32% net-of-fees in the second quarter, with 25.71% for the Russell 2000 Growth Index. Narrow Index leadership hurt the relative results, but it also hid Composite improvements. In addition, please check the Strategy’s top five holdings to know its best picks in 2026.

Conestoga Capital Advisors stated the following regarding AAON, Inc. (NASDAQ:AAON) in its Q2 2026 investor letter:
“AAON, Inc. (NASDAQ:AAON) was among the portfolio’s strongest contributors during the quarter following what we believe was an exceptional first-quarter earnings report. Results highlighted significant demand for the company’s BASX division, which provides liquid-cooling solutions for data centers. Management raised its 2026 BASX revenue outlook to approximately $1.0 billion, up from its previous forecast of $715 million, reflecting accelerating demand from AI-driven data center investments. The company’s rooftop HVAC business also demonstrated a healthy rebound despite ongoing macroeconomic uncertainty. While gross margins declined during the quarter, management intentionally prioritized growth and market share over near-term profitability. We believe this is the appropriate strategy given the robust demand environment and should strengthen AAON’s competitive position over the long term.”
