Cathie Wood’s ARK Invest executed multiple portfolio adjustments on Friday, March 6, 2026, as financial markets wrapped up a volatile trading week. Investor sentiment remained guarded amid escalating U.S.–Iran geopolitical tensions and fresh employment data.

The firm’s daily trading disclosures revealed strategic position changes spanning fintech, technology, and aerospace sectors.

The day’s most significant transaction involved a divestment. ARK liquidated 32,304 Roku shares distributed across several funds, generating approximately $3.17 million in proceeds. This represents a continuation of Roku sales executed earlier in the week, indicating a strategic downsizing of the streaming platform position.

Additionally, ARK divested 86,890 Iridium Communications shares for approximately $2.08 million. Despite the satellite communications provider’s presence in ARK’s investment portfolio, Friday’s transaction signals a strategic retreat from the position.

The asset manager also decreased its 10x Genomics exposure, offloading 75,007 shares worth roughly $1.62 million.

ARK Boosts Aviation and Financial Technology Holdings

Among acquisitions, Joby Aviation emerged as the headline purchase. ARK secured 289,417 shares valued at approximately $2.78 million across its ARKQ and ARKX investment vehicles. The vertical takeoff and landing aircraft developer recently unveiled Q4 2025 financial performance, reporting a per-share loss of $0.14. This represented meaningful improvement from the previous year’s $0.23 loss.

Wood has consistently accumulated Joby shares in the aftermath of these earnings disclosures.

ARK expanded its Robinhood Markets holdings through the acquisition of 19,206 shares totaling approximately $1.55 million. This strategic purchase coincided with a roughly 4% decrease in Robinhood’s share price on Friday. The transactions were distributed among ARK’s ARKK, ARKW, and ARKF investment funds.

Additional March 6 Acquisitions

JD Logistics represented another notable purchase. ARK accumulated 1,129,547 shares for approximately $1.48 million via its ARKX fund. The Chinese logistics provider’s equity surged roughly 22% during Friday’s trading session.

ARK also secured 10,600 DraftKings shares valued at around $269,876.

Supplementary acquisitions encompassed Cerus Corp, Canton Strategic Holdings, and GeneDx Holdings positions.

The firm purchased 84,004 Cerus shares for $170,948, acquired 42,500 Canton Strategic shares for $191,250, and bought 9,113 GeneDx shares for $747,266.

Standard BioTools represented another complete exit, with ARK selling 397,382 shares generating $405,329 in proceeds. ARK additionally reduced its Nextdoor Holdings stake, disposing of 23,100 shares for $38,577.
