Ark Invest executed a series of trades on October 26, 2026, increasing its positions in Joby Aviation, Archer Aviation, Nu Holdings, and Circle Internet Group. Simultaneously, the firm reduced its holdings in Taiwan Semiconductor Manufacturing Co., Advanced Micro Devices, and the ARK 21Shares Bitcoin ETF.
Why it matters
These transactions reflect active portfolio rebalancing by Ark Invest across its thematic exchange-traded funds. The adjustments prioritize specific growth-oriented sectors while scaling back exposure to semiconductor giants and cryptocurrency-linked assets.
Ark Invest added 1,215,866 shares of Archer Aviation and 434,012 shares of Joby Aviation to its holdings. These moves occurred alongside the sale of 601,028 shares of the ARK 21Shares Bitcoin ETF and 24,796 shares of Advanced Micro Devices.
