Cathie Wood’s ARK Investment Management disclosed major portfolio changes on November 11, 2025, with the largest trade involving Chinese e-commerce giant Alibaba. The investment firm purchased 157,731 shares of Alibaba Group Holding Ltd worth $26.2 million.

The Alibaba purchase was split across three ARK exchange-traded funds. The ARK Innovation ETF acquired 117,335 shares, while the ARK Next Generation Fintech ETF bought 33,415 shares. The ARK Fintech Innovation ETF purchased 6,981 shares.

Alibaba Group Holding Limited, BABA

Wood made the purchase as Alibaba shares fell 3.1% that day. The timing suggests the fund manager was buying during a price dip.

ARK also invested in another Chinese tech company on the same day. The funds purchased 14,531 shares of Baidu worth $1.9 million. The ARK Innovation ETF bought 12,006 shares while the ARK Autonomous Technology & Robotics ETF acquired 2,525 shares.

Reddit Position Reduced

On the selling side, ARK divested 40,000 shares of Reddit Inc valued at $8.2 million. The sale was spread between the ARK Next Generation Fintech ETF and ARK Fintech Innovation ETF. Reddit shares rose nearly 2% on November 11.

The Reddit sale represents a major reduction in ARK’s position in the social media platform. This marks one of the fund’s largest single-day sales in the stock.

Healthcare Portfolio Changes

ARK Invest made several moves in the healthcare and biotech sectors. The funds bought 39,250 shares of CRISPR Therapeutics valued at $2.1 million. This purchase continues a pattern of accumulation in CRISPR stock over recent trading days.

The funds also acquired 17,654 shares of Tempus AI Inc for $1.3 million. This healthcare AI company represents part of ARK’s focus on medical technology innovation.

ARK sold 108,664 shares of Exact Sciences Corp for $7.2 million. Exact Sciences, a cancer screening and diagnostic company, saw its shares rise 1.4% that day. The sale appears timed to take advantage of the price increase.

The funds purchased 15,743 shares of Twist Bioscience Corp for $487,403. This synthetic biology company adds to ARK’s biotech holdings.

Additional Trades

ARK continued selling shares of Iridium Communications Inc. The funds sold 192,986 shares worth $3.2 million. Iridium shares increased 1.5% on November 11.

The satellite communications company has been part of a selling trend in ARK portfolios over recent days. The continued divestment suggests a strategic shift away from the stock.

ARK also sold 789 shares of Tesla Inc valued at $351,286. This represents a small adjustment to the fund’s Tesla position.

The November 11 trades show ARK adding to Chinese technology positions while reducing exposure to social media and certain healthcare stocks. The funds invested a total of approximately $27 million in Chinese tech companies that day.
