Cathie Wood Doubles Down on Archer Aviation (ACHR) Post-Q3 Slump—Trims Roku and TER Positions

Cathie Wood's Ark Invest makes bold moves as markets wobble—buying the dip in flying-car hopeful Archer Aviation after a brutal earnings miss, while cutting exposure to streaming play Roku and semiconductor stock TER.

The Contrarian Play:
Wood scoops up ACHR shares as retail investors flee—betting big on urban air mobility despite the company burning cash faster than a jet engine at full throttle.

Portfolio Pruning:
Simultaneously trims stakes in two former darlings—because nothing says 'active management' like selling low after buying high.

The Bigger Picture:
Another classic Ark move—rotating into speculative tech while the market punishes unprofitable growth stocks. Because if there's one thing Wall Street loves, it's doubling down on volatility.

The electric vertical takeoff and landing (eVTOL) startup posted a net loss of $129.9 million for Q3 2025, as spending on its Midnight air taxi project stayed high. R&D costs ROSE to $120.7 million, while the adjusted EBITDA loss was $116.1 million. The company still makes little revenue since it is not yet in full commercial operations.

After the weak Q3 report, the stock fell 9.7% in after trading hours on November 6, and Cathie Wood’s ARK Invest used the dip to buy 3,012,500 shares worth about $28.83 million across three funds.

Biotech and Genomics Buys Continue

ARK also remained active in the biotech space. The firm added 123,206 shares of BEAM Therapeutics (BEAM), worth about $2.84 million, showing continued confidence in the company’s gene-editing technology.

In addition, ARK bought 195,084 shares of 10x Genomics (TXG) for $2.63 million, and 252,561 shares of Pacific Biosciences (PACB) worth $483,654, reinforcing its focus on genomics and life sciences.

ARK Trims Roku, Teradyne, and Healthcare Stocks

On the sell side, ARK trimmed 160,812 shares of Roku (ROKU), valued at $16.99 million. This continues a series of Roku sales throughout the week as ARK reduces exposure to the streaming platform stock.

Also, ARK sold 18,025 shares of Teradyne (TER) for $3.38 million. The company makes testing equipment for chips and industrial robots.

In healthcare, ARK trimmed 247,071 shares of Exact Sciences (EXAS), worth $17.20 million, and cut 80,550 shares of Ionis Pharmaceuticals (IONS) for about $6.02 million.
