ARK Investment Management, led by Cathie Wood, made significant adjustments to its portfolio on Monday, August 25, 2025. The most notable transaction involved selling 141,194 shares of Roku Inc (NASDAQ:ROKU), worth $13,303,298 [1]. This move is part of a broader trend of reducing ARK's exposure to the streaming device company.

On the buying side, ARK made substantial investments in CRISPR Therapeutics AG (NASDAQ:CRSP) and Intellia Therapeutics Inc (NASDAQ:NTLA). ARK acquired 188,879 shares of CRISPR for $10,259,907 and 359,000 shares of Intellia for $3,776,680 [1]. These purchases indicate a strong bullish stance on gene-editing companies, aligning with ARK's focus on innovative healthcare solutions.

Additionally, ARK increased its investment in PagerDuty Inc (NYSE:PD) by purchasing 90,214 shares, valued at $1,508,378 [1]. This move follows a pattern of buying into the company, suggesting a growing interest in the cloud computing sector.

ARK also sold 1,045 shares of Guardant Health Inc (NASDAQ:GH) for $64,163 [1]. This sale is relatively small compared to other transactions but is part of a series of sales of GH shares over the past week.

The trading activity reflects ARK's strategic pivot towards biotech, particularly companies involved in gene editing and therapeutics, while gradually reducing exposure to certain tech companies. Investors following ARK's movements may interpret these trades as a sign of Wood's shifting focus towards innovative healthcare solutions.
