Cathie Wood’s ARK Invest made a series of portfolio moves on Monday, May 18, 2026, according to the firm’s daily trade disclosures. The trades show a clear shift away from semiconductor stocks and toward defense, e-commerce, and electric aviation.

The biggest sale of the day was Advanced Micro Devices. ARK offloaded 38,529 shares worth $16.3 million across its ARKK, ARKW, and ARKF funds. AMD stock has nearly doubled this year, up roughly 98%, driven by strong demand for AI chips and data center hardware.

ARK also sold Taiwan Semiconductor shares worth $12.1 million. The stock is up more than 33% year-to-date, making it another semiconductor name ARK chose to trim after a strong run.

Teradyne was a third semiconductor exit. ARK sold about $14.7 million in shares. The chip-testing equipment company has gained over 74% this year on the back of rising AI-related demand.

ARK’s Biggest Buys

The largest purchase of the day was L3Harris Technologies, a defense contractor. ARK bought around $3.18 million in shares through its ARKX ETF. The stock rose 2.5% on Monday, reflecting wider investor interest in defense spending.

ARK also added nearly $1.84 million in Amazon shares. The company is a major player in cloud computing through Amazon Web Services and is up more than 14% year-to-date.

Archer Aviation received roughly $1.7 million in new investment from ARK. The electric air taxi company is down about 20% this year, but analysts still project more than 100% upside.

Joby Aviation was another air taxi buy. ARK added about $1.23 million in shares. Both Archer and Joby operate in the electric vertical takeoff and landing market, known as eVTOL.

Other Notable Moves

ARK bought 52,308 shares of Bullish worth $1.87 million and 45,218 shares of Kratos Defense and Security Solutions for $2.36 million. These add to ARK’s growing defense and fintech exposure.

On the sell side, ARK reduced its Roku position by offloading 45,320 shares worth $5.6 million. It also trimmed 145,039 shares of Rocket Lab, worth roughly $5.6 million. Rocket Lab stock jumped another 5% on Monday and is now up nearly 79% year-to-date.

The overall pattern from Monday’s trades points to ARK locking in profits from semiconductor and space stocks that have had strong 2026 runs.

Capital is being redirected into defense contractors, aviation startups, and large-cap tech like Amazon. This follows ARK’s stated focus on disruptive, forward-looking sectors.

Citi analyst Atif Malik raised his AMD price target to $460 from $358 on Monday, citing growing AI server CPU demand. That upgrade came on the same day ARK was selling the stock.
