Cathie Wood’s ARK Invest made a series of trades on Friday, March 6, 2026, as markets closed out a turbulent week. Rising U.S.–Iran tensions and the latest jobs report kept investors cautious heading into the weekend.
ARK’s daily trade disclosures showed a mix of buys and sells across technology, fintech, and aviation stocks.
The biggest trade of the day was a sale. ARK sold 32,304 shares of Roku across multiple funds for about $3.17 million. This follows earlier Roku sales the same week, pointing to a deliberate reduction of the position.
ARK also sold 86,890 shares of Iridium Communications for roughly $2.08 million. The satellite communications firm has been among ARK’s portfolio holdings, but Friday’s move suggests a pullback.
The firm also reduced its stake in 10x Genomics, selling 75,007 shares valued at around $1.62 million.
ARK Adds to Electric Aviation and Fintech
On the buying side, Joby Aviation was the standout. ARK purchased 289,417 shares worth approximately $2.78 million through its ARKQ and ARKX funds. The electric air-taxi company recently reported Q4 2025 results, posting a loss of $0.14 per share. That was narrower than the $0.23 loss recorded a year earlier.
Wood has been buying Joby shares following those earnings results.
ARK also added to its Robinhood Markets position, buying 19,206 shares for about $1.55 million. The purchase came as Robinhood shares fell roughly 4% on Friday. The buys were spread across ARK’s ARKK, ARKW, and ARKF funds.
Other Buys on March 6
JD Logistics was another buy. ARK picked up 1,129,547 shares for about $1.48 million through its ARKX fund. The logistics company’s stock jumped roughly 22% on the day.
ARK also added 10,600 shares of DraftKings for around $269,876.
Smaller purchases included Cerus Corp, Canton Strategic Holdings, and GeneDx Holdings.
ARK bought 84,004 shares of Cerus for $170,948, 42,500 shares of Canton Strategic for $191,250, and 9,113 shares of GeneDx for $747,266.
Standard BioTools was another name ARK exited, selling 397,382 shares for $405,329. ARK also trimmed Nextdoor Holdings, selling 23,100 shares for $38,577.
The trades were disclosed through ARK’s standard daily filing on March 6, 2026.
