Wood offloaded 29,130 shares, pocketing roughly $8.6 million. This continues a recent trend of reducing her position in the chip equipment company as the semiconductor testing market matures. The stock reflected this slowing momentum, closing 7% lower on Monday. ## **Wood Buys the Dip in CRWV and OKLO** While Teradyne was a clear exit, Wood used a sharp sell-off in CoreWeave as a golden entry point. She poured over $3.1 million into the AI-focused cloud provider just as CRWV stock tumbled nearly 8%. The slide was triggered by news that CoreWeave's CEO, Michael Intrator, recently sold over $7.2 million worth of company stock. While the "insider selling" headline spooked retail investors, Wood viewed the dip as a great opportunity. ARK also bought 37,422 shares of Oklo, worth about $1.8 million, buying the dip after the stock fell about 9% on Monday. The move shows Wood's growing focus on nuclear energy, as data centers need large amounts of clean power, with Oklo's small modular reactors seen as a long-term solution. In healthcare, the firm bought 20,674 shares of GeneDx (WGS) for around $1.18 million, showing continued interest in genomics and precision medicine. ## **How Wall Street Views These Stocks** Let's see how these stocks perform using the TipRanks Stock Comparison Tool. ### Related Stocks - [ALPS Medical Breakthroughs ETF (SBIO.US)](https://longbridge.com/en/quote/SBIO.US.md) - [iShares Biotechnology ETF (IBB.US)](https://longbridge.com/en/quote/IBB.US.md) - [VanEck Semiconductor ETF (SMH.US)](https://longbridge.com/en/quote/SMH.US.md) - [Defiance Daily Target 2X Long OKLO ETF (OKLL.US)](https://longbridge.com/en/quote/OKLL.US.md) - [Direxion Daily S&P Biotech Bull 3X ETF (LABU.US)](https://longbridge.com/en/quote/LABU.US.md) - [State Street® SPDR® S&P® Biotech ETF (XBI.US)](https://longbridge.com/en/quote/XBI.US.md) - [Oklo Inc.
