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: high-beta stocks outperformed while high-quality companies lagged, affecting 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 Micro-Cap Composite achieved a solid second quarter with a 22.16% net return, although it underperformed the Russell Microcap Growth Index’s 28.98% return. During this period, Micro-Cap Growth surpassed all major equity benchmarks, which reflects improved investor sentiment towards smaller-cap stocks, but the gains were primarily driven by a limited set of high-beta, high-momentum stocks.

“Onterris, Inc. (NYSE:ONT) provides environmental testing, consulting, and remediation services to commercial and government customers. The stock declined after first quarter revenue fell short of the prior year as lower environmental emergency response activity and severe winter weather weighed on results. Management maintained full-year guidance, noting underlying demand remained healthy despite these temporary headwinds. We continue to believe ONT’s integrated environmental services platform and expanding client relationships support an attractive long-term outlook.”
