Cathie Wood's ARK Invest has made notable portfolio adjustments in early August 2025, focusing on semiconductor and technology stocks amid evolving market conditions and regulatory changes. On August 5, ARK Invest acquired 23,200 shares of Nvidia, reflecting confidence in the company's growth potential following the White House's decision to lift the AI chip export ban to China. Alongside Nvidia, ARK also increased its holdings in Advanced Micro Devices (AMD), purchasing over 23,400 shares valued at approximately $4.1 million ahead of AMD's earnings report. These combined buys in AMD and Nvidia totaled more than $8 million. Additionally, ARK trimmed its positions in Robinhood Markets amid changing cryptocurrency regulations. On August 7, ARK Invest further demonstrated renewed conviction in AMD by acquiring roughly $38 million worth of its stock across multiple ETFs after a price decline exceeding 6%, signaling confidence in AMD's AI chip roadmap. On the same day, ARK also bought 179,197 shares of Airbnb, expanding its exposure in the technology and consumer sectors. Concurrently, ARK reduced stakes in companies including Roblox, Palantir, Shopify, DraftKings, Guardant Health, Kratos Defense, Robinhood, and others. These moves underscore ARK's strategic focus on innovation-driven companies while managing portfolio risks in a volatile market environment.
