Cathie Wood’s ARK trims AMD again, adds Rocket Lab as space-themed bets return

Cathie Wood’s ARK funds have reportedly adjusted their exchange-traded holdings once more, cutting back on AMD while adding Rocket Lab, according to a market report published Tuesday by Yahoo Finance. The move comes amid recent weakness in parts of the technology sector, with ARK indicating a willingness to rotate toward industries it views as tied to long-duration innovation themes, including space.

The Yahoo report says ARK reduced its stake in AMD, a maker of computer and data-center semiconductors, and simultaneously initiated or increased exposure to Rocket Lab, a space systems company that builds rockets and provides launch-related services. The article frames the change as part of ARK’s shifting allocation away from broad tech exposure and toward space-focused names.

AMD and Rocket Lab are both frequently held by growth-oriented investors, but they sit at different points of the risk and demand curve. AMD’s valuation and earnings outlook are closely tied to semiconductor cycles, customer spending on computing and data centers, and the competitive landscape against other chip suppliers. Rocket Lab’s trajectory is more dependent on execution of rocket programs, scaling of launch cadence, and the pace at which customers expand demand for space access.

ARK’s reported activity highlights a recurring pattern among active exchange-traded fund managers. When markets reprice growth and long-duration assets, managers can respond by rebalancing toward themes they believe have stronger long-term catalysts, even if near-term volatility remains high. In ARK’s case, the Yahoo report suggests the manager is leaning more heavily into space after tech’s selloff.

The report does not provide, in the text available for this review, specific trade sizes, dollar amounts, or the exact ARK funds that executed each leg of the move. It also does not disclose whether AMD was trimmed across multiple ARK strategies or whether Rocket Lab was added into a single vehicle, nor does it detail whether the trades were reductions of existing positions or new buys.

For AMD, portfolio cuts by a prominent manager can matter mostly as a sentiment indicator rather than a direct driver of near-term fundamentals, unless disclosed trades are large relative to the stock’s daily liquidity. Still, AMD remains a widely owned semiconductor stock, and repeated adjustments by a high-profile investor can influence how other investors read the outlook for chips used in computing and cloud infrastructure.

For Rocket Lab, being added by an ARK-linked portfolio can be interpreted as increased emphasis on its commercial space thesis. The company’s business model is generally understood to include launch services and space systems, with investors watching milestones such as vehicle performance, manufacturing scale, and customer contracting. However, the Yahoo report does not add new operational updates in the available text, so the key takeaway is the portfolio reallocation rather than a fundamental change announced by Rocket Lab itself.

Investors and traders typically look next for whether ARK’s filings and subsequent disclosures confirm the timing and magnitude of the AMD sell and Rocket Lab add, including which specific ARK funds were involved. The other question will be whether the rotation persists into other space-linked holdings or whether the moves reflect a tactical adjustment tied to the most recent market volatility rather than a sustained shift in the firm’s strategy.
