ARK Invest, the exchange-traded fund managed by prominent investor Cathie Wood, adjusted several holdings on March 3, increasing positions in select technology and aviation stocks while reducing others.

Among the acquisitions, ARK purchased 138,270 shares of Alibaba (BABA) stock, valued at approximately $18.75 million. The stock declined nearly 5% that day amid broader market weakness driven by geopolitical tensions. The firm also added 62,579 shares of Amazon.com (AMZN), worth around $13 million, following reports that some of its data center operations were affected by regional instability.

ARK expanded its exposure to electric vertical takeoff and landing aircraft manufacturers by buying 947,943 shares of Archer Aviation (ACHR), valued at about $6.37 million, and 539,131 shares of Joby Aviation (JOBY), worth approximately $5.26 million. Archer recently reported a fourth-quarter loss per share of $0.26 and remains in a pre-revenue phase. The fund also acquired 122,951 shares of BioNTech (BNTX), amounting to roughly $12.39 million.

On the divestment side, ARK reduced its positions in Roku (ROKU), Taiwan Semiconductor Manufacturing (TSM), and Baidu (BIDU), selling off shares valued at over $31 million, $14 million, and $12 million, respectively.
