ClearBridge Investments, a global equity manager, recently published second-quarter 2026 commentary for its “Small Cap Growth Strategy”. A copy of the letter can be downloaded here. The Russell 2000 Growth Index increased by 25.6% in the second quarter, marking its third-best quarterly performance in two decades. The rally was fueled by enthusiasm for AI, strength in biotech, and gains in high-beta, high-momentum stocks, amid rising retail trading activity and narrow leadership in specific themes. Despite a complex macroeconomic backdrop and ongoing debates about the pace and impact of AI infrastructure investments, enthusiasm for generational technology investments remains robust. The Strategy achieved strong absolute returns of over 21% (gross) during the quarter but lagged the Russell 2000 Growth benchmark due to underperformance in certain healthcare and financial stocks, software challenges, and limited exposure to high-beta, high-momentum AI-related stocks. In addition, please check the Strategy’s top five holdings to know its best picks in 2026.
