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.
