Impax Asset Management, a London-based firm specializing in sustainable investing, detailed its Q2 2026 performance in its investor letter for the Impax US Sustainable Economy Fund. The fund outperformed the Russell 1000 index with various classes, boasting an impressive average return of 17.94% across Institutional, Investor, and Class A categories, compared to the index's 15.14%.

The portfolio's success was driven by sector allocation and stock selection, with a notable trend favoring AI and tech stocks. The Impax Sustainability Lens and Corporate Resilience framework were pivotal in this performance. The letter also highlighted Advanced Micro Devices (AMD), a semiconductor company specializing in AI accelerators, microprocessors, and graphics processing units.

AMD's stock rose significantly in Q2 2026, partly due to strong adoption of its AI-optimized GPU and data center processor products, and major partnerships with cloud computing providers. The fund believes AMD offers strong growth potential tied to energy security and efficiency, making it a compelling pick amidst market volatility.
