Cathie Wood’s investment firm ARK Invest executed notable portfolio adjustments on Monday, May 18, 2026, as revealed in the company’s publicly available daily transaction reports. The trading activity demonstrates a strategic pivot away from chip manufacturers and into defense technology, online retail, and electric aviation sectors.

Advanced Micro Devices represented the day’s most substantial divestment. The firm liquidated 38,529 shares valued at $16.3 million distributed among its ARKK, ARKW, and ARKF exchange-traded funds. AMD’s stock price has surged approximately 98% year-to-date, fueled by robust artificial intelligence chip demand and data center equipment sales.

Taiwan Semiconductor also faced significant selling pressure from ARK, with the firm disposing of $12.1 million in holdings. The chipmaker’s shares have climbed over 33% since January, positioning it as another semiconductor holding that ARK decided to reduce following substantial gains.

Teradyne represented a third semiconductor divestment. ARK unloaded approximately $14.7 million in the chip-testing equipment manufacturer. The company’s stock has appreciated more than 74% this year, benefiting from expanded AI-related testing requirements.

ARK’s Biggest Buys

Defense contractor L3Harris Technologies claimed the top spot among ARK’s acquisitions. The firm purchased approximately $3.18 million in shares through its ARKX space exploration ETF. L3Harris stock advanced 2.5% during Monday’s session, mirroring broader market enthusiasm for defense sector investments.

ARK injected nearly $1.84 million into Amazon shares. The e-commerce and technology giant dominates cloud computing services through its Amazon Web Services division and has posted gains exceeding 14% since the year began.

Archer Aviation attracted roughly $1.7 million in fresh capital from ARK. Despite the electric air taxi developer trading down approximately 20% year-to-date, Wall Street analysts maintain price targets suggesting potential upside exceeding 100%.

Joby Aviation secured another air taxi investment from ARK. The firm allocated about $1.23 million to shares of the company. Both Archer and Joby compete in the emerging electric vertical takeoff and landing sector, commonly referred to as eVTOL.

Other Notable Moves

ARK acquired 52,308 shares of Bullish valued at $1.87 million and 45,218 shares of Kratos Defense and Security Solutions totaling $2.36 million. These purchases expand ARK’s presence in both defense technology and financial technology sectors.

Among disposals, ARK decreased its Roku holdings by selling 45,320 shares worth $5.6 million. The firm also cut 145,039 shares of Rocket Lab, representing approximately $5.6 million. Rocket Lab stock surged an additional 5% on Monday and has now rallied nearly 79% since January.

The aggregate trading pattern from Monday reveals ARK capitalizing on semiconductor and aerospace stocks that have delivered exceptional 2026 performance.

Proceeds are flowing into defense industry players, aviation innovators, and established technology leaders like Amazon. This realignment aligns with ARK’s investment philosophy emphasizing disruptive and transformative market sectors.

Citi analyst Atif Malik elevated his AMD price target to $460 from $358 on Monday, pointing to accelerating AI server CPU adoption. Interestingly, this bullish revision coincided exactly with ARK’s decision to exit the position.
