Cathie Wood’s Ark Invest, in a broad selloff, reduced its positions in artificial intelligence, crypto, and internet stocks.

Over the past week, more than 57 thousand shares of Advanced Micro Devices $AMD were sold, while more than 18 thousand shares of Taiwan Semiconductor Manufacturing $TSM were sold. Broadcom $AVGO was also trimmed on a smaller scale. These moves point to profit-taking and portfolio rebalancing across the AI supply chain, along with a reduction in Teradyne $TER, where the total sales came close to $24M and amounted to just under 82 thousand shares.
On the large-cap internet and platform side, ARK sold more than 90 thousand shares of Meta Platforms $META, worth nearly $50M, while also cutting its Alphabet $GOOG position by 9 thousand shares. The fund manager also further reduced its holdings in Netflix $NFLX, Spotify Technology $SPOT, and Pinterest $PINS.
ARK reduced its position in Block (XYZ) by about 107 thousand shares, worth roughly $6M, and also made modest reductions in Sea (SE) and DoorDash (DASH). These moves suggest a broad-based risk-reduction strategy across consumer internet and digital platform stocks.
ARK also aggressively lightened positions in high-beta and speculative innovation names, including a 631 thousand share position in Recursion Pharmaceuticals $RXRX. It sold 899 thousand shares of Archer Aviation $ACHR, while Roku $ROKU saw a large multi-day selling program covering more than 234 thousand shares. The fund also reduced its stakes in Beam Therapeutics $BEAM and Twist Bioscience $TWST. Selling activity in healthcare also included names such as Illumina $ILMN, Veracyte $VCYT, Ionis Pharmaceuticals $IONS, and Natera $NTRA.
The firm also narrowed its exposure in Kratos Defense & Security Solutions $KTOS and BWX Technologies $BWXT, signaling a broader reduction in defense and aerospace exposure. In addition to continuing to sell Bullish $BLSH, ARK also reduced its stake in its own ARK 21Shares Bitcoin ETF $ARKB.
One important note: last week’s activity was dominated by selling, with only a limited number of new stocks added to the portfolio. The only companies that made it onto ARK’s buy list were Circle Internet $CRCL, Tempus AI $TEM, 10x Genomics $TXG, and Arcturus Therapeutics $ARCT.
Through its ARKF, ARKK, and ARKW funds, ARK bought more than 161 thousand shares of Circle Internet Group $CRCL, valued at around $16M-$17M.
Healthcare and genomics were the main sectors where accumulation took place: through ARKK and ARKG, ARK purchased about 146 thousand shares of Tempus AI, worth around $7M, while also adding more than 121 thousand shares of 10x Genomics (TXG), worth close to $2.5M.
In addition, the portfolio manager bought more than 53 thousand shares of Arcturus Therapeutics (ARCT).
