Investment management company Artisan Partners stated in its Q2 2026 investor commentary that its Artisan Global Opportunities Strategy fund trimmed its exposure to Advanced Micro Devices (AMD) as the valuation moved beyond its reasonable expectations, consistent with its valuation discipline. AMD shares gained 182.50% over the past 52 weeks, driven by continued strength in data center demand and AI infrastructure. The fund had previously added to its position ahead of the stock's rally.
