ARK ETFs, managed by Cathie Wood, have been active in their daily trades, reflecting a dynamic investment strategy. On July 2nd, 2025, the ETFs made several notable transactions, indicating a shift in focus towards specific sectors and companies.

One of the significant moves involved the purchase of 28,375 shares of AeroVironment Inc (NASDAQ:AVAV) by ARKQ and ARKX ETFs, totaling approximately $7.16 million [1]. This acquisition follows a pattern of recent interest in the aerospace and defense sector. Additionally, ARKG expanded its position in Beam Therapeutics Inc (NASDAQ:BEAM) by acquiring 54,969 shares, valued close to $963,606, further demonstrating ARK’s interest in biotech firms [1].

ARKK also increased its holdings in Compass Pathways PLC (NASDAQ:CMPS) by buying 39,681 shares worth $125,391, continuing its investment in mental health care companies [1]. On the sell side, ARK ETFs divested from several companies, including Coinbase Global Inc (NASDAQ:COIN), selling 3,067 shares through ARKW for approximately $1.03 million. This continues a trend of ARK reducing its stake in the cryptocurrency exchange platform [1].

ARKQ sold a significant number of shares in Komatsu Ltd (OTC:KMTUY), offloading 199,192 shares for about $6.5 million, suggesting a major portfolio adjustment [1]. The ARKG fund sold 24,328 shares of Ionis Pharmaceuticals Inc (NASDAQ:IONS) for nearly $971,660 and 145,829 shares of 908 Devices Inc (NASDAQ:MASS) for approximately $944,971, indicating a possible shift away from these healthcare and technology plays [1].

ARKK sold 72,203 shares of Roblox Corp (Pre-Reincorporation) (NYSE:RBLX) for a substantial $7.27 million, following sales on previous days. This appears to be part of a larger sell-off trend for the gaming platform’s stock within ARK’s portfolio [1].

Investors should note the continued diversification in sectors such as aerospace, biotech, and technology, while observing the fund’s dynamic strategy of capitalizing on market movements and adjusting holdings to optimize growth potential.
