Cathie Wood’s ARK ETFs were active in the market on Wednesday, August 6, 2025, with a series of trades that saw significant buying and selling across various sectors. The largest dollar-value trade was a purchase of Advanced Micro Devices Inc (NASDAQ:AMD), totaling $40,961,455, spread across multiple ARK funds, indicating a strong bullish stance on the semiconductor company.

Following AMD, ARK’s next significant investment was in Twist Bioscience Corp (NASDAQ:TWST), with a total of 300,219 shares acquired for $8,262,026. This move suggests ARK’s continued focus on the genomics sector, as Twist Bioscience specializes in synthetic DNA for industries including healthcare, agriculture, industrial chemicals, and data storage.

On the selling side, ARK divested a substantial number of shares in Shopify Inc (NYSE:NASDAQ:SHOP), amounting to $15,061,565, which was the largest sale by dollar value for the day. The sale of 111,803 shares of Roblox Corp (PRE-REINCORPORATION) (NYSE:RBLX) for $14,211,279 also stood out, indicating a potential shift in ARK’s confidence in the gaming platform’s prospects.

Other notable buys included 186,013 shares of Aurora Innovation Inc (NASDAQ:AUR) and 230,005 shares of GeneDx Holdings Corp (NASDAQ:WGS), with total dollar values of $1,145,840 and $2,453,483, respectively. These trades underscore ARK’s commitment to innovation and technology in the automotive and genomics industries.

On the sell side, ARK reduced its holdings in Palantir Technologies Inc (NYSE:NASDAQ:PLTR), selling 63,279 shares for $10,964,352, and in Kratos Defense and Security Solutions Inc (NASDAQ:KTOS), selling 103,810 shares for $6,166,314. These sales may reflect ARK’s strategy to rebalance its portfolio or take profits in these sectors.

Smaller trades included purchases of Compass Pathways PLC (NASDAQ:CMPS), Ibotta Inc (PRIVATE:IBTA), and Toast Inc (NYSE:TOST), as well as sales of Adaptive Biotechnologies Corp (NASDAQ:ADPT), Amgen Inc (NASDAQ:AMGN), and Ionis Pharmaceuticals Inc (NASDAQ:IONS).

Looking at the trends, ARK has been consistently investing in Advanced Micro Devices Inc (AMD) and Aurora Innovation Inc (AUR) over the past week, suggesting a bullish outlook on these companies. Conversely, the consistent selling of Roblox Corp (RBLX) could indicate a change in strategy or a response to market conditions.

Investors following Cathie Wood’s ARK ETFs should note these trades as part of ARK’s dynamic investment approach, focusing on disruptive innovation and technology. While individual trades do not necessarily indicate long-term trends, they offer insight into ARK’s market moves and potential strategic shifts.
