Cathie Wood’s ARK ETFs have published their daily trades for Thursday, 21 August 2025, unveiling a series of strategic buy and sell moves in the tech and biotech sectors. The most significant transaction of the day was the purchase of 138,706 shares of PagerDuty Inc (NYSE:PD) by the ARK Innovation ETF (NYSE:ARKK), amounting to approximately $2,223,457.
In another notable trade, ARK’s funds continued their recent accumulation trend in Intellia Therapeutics Inc (NASDAQ:NTLA). ARKK and ARK Genomic Revolution ETF (ARKG) together bought a total of 91,050 shares, valued at $929,620. This follows substantial purchases of the stock earlier in the week, indicating a growing bullish stance on the gene-editing company.
On the sell side, ARK Fintech Innovation ETF (NYSE:ARKF) divested 14,914 shares of Robinhood Markets Inc (NASDAQ:HOOD), withdrawing $1,571,040 from the online brokerage. This move contrasts sharply with the fund’s more aggressive buys of Robinhood shares earlier in the week, suggesting a possible rebalancing or a change in outlook.
ARKF also reduced its holdings in streaming device company Roku Inc (NASDAQ:ROKU) by selling 16,128 shares, totaling $1,426,844, and in e-commerce platform Shopify Inc (NYSE:NASDAQ:SHOP), offloading 11,711 shares for $1,607,803. These sales may reflect a broader strategy shift or a response to recent market developments.
The ARK ETFs are known for their active management and focus on disruptive innovation. Investors closely monitor their daily trades for insights into Wood’s latest convictions on high-growth potential stocks. The recent trading patterns suggest a continued interest in biotech, particularly in companies involved in gene editing and therapeutics, while taking a more varied approach to tech stocks.
