Tracking Cathie Wood: Aggressively adding to aerospace and energy stock LUNR, broadly reducing positions in consumer and healthcare names

On Tuesday, July 28, 2026, the three major U.S. indices diverged. The Dow Jones Industrial Average led gains, surging 1.03% to close at 52,747.32, signaling strong investor appetite for traditional blue-chip stocks; the S&P 500 edged up modestly by 0.21% to close at 7,428.78; meanwhile, the tech-heavy Nasdaq declined 0.22% against the trend, closing at 24,876.91, reflecting clear divergence within the technology sector.

Against this backdrop, Cathie Wood focused her buying power on 'hard tech' sectors such as aerospace, nuclear energy, and AI infrastructure on the day, while significantly reducing positions across a broad range of holdings in consumer, healthcare, and fintech—sending a clear rebalancing signal of 'de-diversification and strong concentration.'

Buying focus: Concentrating on aerospace, nuclear energy, and AI infrastructure, doubling down on disruptive hard tech

The largest purchase of the day was $Intuitive Machines (LUNR.US)$, with an aggressive addition of 983,027 shares—an unusually large move. Intuitive Machines is a leading U.S. lunar exploration infrastructure company and has recently continued to secure contracts under NASA’s Commercial Lunar Payload Services (CLPS) program. ARK’s substantial stake increase likely reflects its confidence in the long-term visibility of commercial orders driven by the expanding U.S. government budget for deep-space exploration.

Following closely behind, $SpaceX (SPCX.US)$ received an addition of 105,108 shares, and $Rocket Lab (RKLB.US)$ received an addition of 62,497 shares. Together, these two positions form ARK’s systematic investment across the full ‘new space economy’ value chain—from heavy-lift launch capabilities to small satellite deployment—signaling continuous expansion of ARK’s aerospace footprint.

The nuclear energy sector also garnered significant attention from ARK.$X-Energy (XE.US)$ received an addition of 97,098 shares, and $BWX Technologies (BWXT.US)$ received an addition of 35,130 shares.

As surging global AI computing demand drives explosive growth in electricity consumption, small modular reactors (SMRs) are seen as a core solution for next-generation clean baseload power. ARK’s move may be betting on the long-term thesis of a deep linkage between nuclear energy and AI computing demand.

In terms of core tech holdings,$NVIDIA (NVDA.US)$received an increase of 78,965 shares,$Tesla (TSLA.US)$received an increase of 40,281 shares. As the dominant infrastructure provider for AI computing, NVIDIA continues to be added to by ARK, reflecting its long-term conviction that the AI supercycle has not yet peaked; for Tesla, progress in autonomous driving and robotics likely remains the core narrative underpinning ARK’s continued position.

$Kratos Defense & Security Solutions (KTOS.US)$received an increase of 50,536 shares,$Kodiak AI (KDK.US)$received an increase of 35,220 shares. The former specializes in drones and defense technology, while the latter focuses on military autonomous driving systems—both pointing to ARK’s view on the emerging theme of AI-enabled defense applications.

Additionally, in autonomous driving-related holdings, $Pony AI (PONY.US)$received an increase of 20,659 shares, further strengthening ARK’s positioning density in embodied intelligence and autonomous driving.

In the digital assets segment,$Bitmine Immersion Technologies (BMNR.US)$received an increase of 16,458 shares, and 3iQ Solana Staking ETF (SOLQ.U.US) received an increase of 5,252 shares, indicating ARK’s continued advancement of a diversified allocation across the crypto ecosystem.

Selling direction: Broad-based portfolio streamlining to release capital for concentrated allocations in hard tech.

The largest position reduced was $Genius Sports (GENI.US)$, with a reduction of 292,255 shares. Genius Sports primarily provides sports data and betting technology services, which are relatively peripheral to ARK’s core 'disruptive innovation' theme. This reduction may reflect ARK’s ongoing reallocation away from non-core sectors to free up capital for hard tech investments.

$Iridium Communications (IRDM.US)$was reduced by 184,670 shares. Notably, on the same day, ARK bought shares in SpaceX and Rocket Lab, potentially signaling an intra-sector rotation within satellite communications—shifting from traditional low-orbit satellite operators toward more growth-oriented commercial aerospace infrastructure plays.

The healthcare and life sciences sector also saw adjustments.$CRISPR Therapeutics (CRSP.US)$was reduced by 108,908 shares,$Twist Bioscience (TWST.US)$was reduced by 39,594 shares,$10x Genomics (TXG.US)$was reduced by 25,096 shares,$Veracyte (VCYT.US)$was reduced by 20,539 shares,$Natera (NTRA.US)$was reduced by 6,771 shares$Strata Critical Medical (SRTA.US)$85,495 shares were sold. Such concentrated selling in the healthcare sector likely reflects ARK’s broader rebalancing of its precision medicine positions or a reassessment of near-term catalysts and R&D progress for certain holdings.

Fintech and consumer platform stocks were also broadly reduced.$Bullish (BLSH.US)$70,638 shares were sold,$Robinhood (HOOD.US)$43,420 shares were sold,$Block (XYZ.US)$27,777 shares were sold,$Roblox (RBLX.US)$69,135 shares were sold,$DraftKings (DKNG.US)$33,008 shares were sold,$Shopify (SHOP.US)$15,187 shares were sold,$Roku Inc (ROKU.US)$7,774 shares were sold. These holdings span crypto finance, gaming/social platforms, and consumer e-commerce, suggesting ARK is systematically narrowing its exposure and reallocating capital toward disruptive hard-tech names with higher conviction.

Large-cap tech stocks $Amazon (AMZN.US)$was reduced by 9,895 shares,$Alphabet-A (GOOGL.US)$was reduced by 6,820 shares; industrial giant $Honeywell (HON.US)$was reduced by 20,471 shares,$Teledyne Technologies (TDY.US)$was reduced by 20,178 shares,$Deere (DE.US)$was reduced by 9,569 shares,$Caterpillar (CAT.US)$was reduced by 3,328 shares,$Elbit Systems (ESLT.US)$was reduced by 3,400 shares, and $Trimble (TRMB.US)$was reduced by 47,817 shares,$Brera Holdings (SLMT.US)$was reduced by 931 shares, all reflecting ARK's common trend of reducing exposure to traditional industrials and large-cap tech, with capital flows clearly shifting toward early-stage disruptive innovation targets.
