Symbols

Buying Focus: Concentrating on the core themes of AI computing power, cybersecurity, and precision medicine.

$ARK Active Autocallable Income ETF (ARKY.US)$ Significantly increased holdings by 1 million shares, a scale far exceeding other targets. ARKY is ARK's flagship income-oriented ETF product. This move may reflect ARK's strategy to strengthen liquidity management and overall portfolio resilience by increasing allocation to its own income products amidst market volatility.

$Cerebras Systems (CBRS.US)$ Increased holdings by 78,756 shares. Cerebras is an emerging challenger in the AI computing chip sector, with its Wafer Scale Engine technology offering differentiated competition against Nvidia. ARK's continued accumulation may aim to capture opportunities in non-mainstream computing assets amid the explosion of demand for AI infrastructure.

$Cloudflare (NET.US)$ Increased holdings by 60,805 shares. As a global leader in cybersecurity and edge computing platforms, Cloudflare has recently continued to expand its AI workload security capabilities, aligning with ARK's long-term investment thesis on 'AI security infrastructure.'

$Broadcom (AVGO.US)$ Increased holdings by 55,548 shares. Broadcom is a key player in the global custom AI chip (ASIC) market, deeply integrated with tech giants like Google and Meta. ARK's recent increase in holdings may reflect its long-term bullishness on core segments of the AI hardware supply chain.

$Freenome (FRNM.US)$ Increased holdings by 55,173 shares. Freenome focuses on early cancer liquid biopsy based on multi-omics technology, fitting ARK's core investment framework for precision medicine. The continued increase in holdings may indicate ARK's high confidence in the commercialization progress of its technology platform.

$Rocket Lab (RKLB.US)$ Increased holdings by 34,370 shares. Rocket Lab continues to expand in small satellite launch and space system manufacturing. As the competitive landscape of the commercial space market becomes clearer, ARK's increased position may be based on its continued recognition of Rocket Lab's long-term competitiveness.

$Ionis Pharmaceuticals (IONS.US)$ Increased holdings by 18,499 shares. Ionis is a global pioneer in antisense oligonucleotide (ASO) therapy, with a widely applicable technology platform. ARK's slight increase in holdings may be part of its ongoing strategy to position itself in the precision gene therapy sector.

$Securitize (SECZ.US)$ Increased holdings by 16,314 shares. Securitize is a major infrastructure provider for the tokenization of real-world assets (RWA). This increase in holdings may reflect ARK's continued focus on the long-term trend of integrating blockchain with traditional financial assets.

Sell-side direction: Adjusting positions in metaverse, genomics, and high-valuation tech stocks.

$Roblox (RBLX.US)$ Reduced holdings by 501,466 shares, the largest reduction of the day. Roblox operates in the metaverse entertainment platform sector. Against the backdrop of slowing user growth and commercialization pace falling short of expectations, ARK's significant reduction may be a major move to adjust its portfolio structure.

$10x Genomics (TXG.US)$ Reduced holdings by 203,242 shares. 10x Genomics has established certain technical barriers in the field of spatial genomics, but recent funding pressures in the industry suggest that ARK's reduction may be a reallocation of capital to targets with stronger catalysts.

$Twist Bioscience (TWST.US)$ Reduced holdings by 75,445 shares. Twist is a key player in the synthetic biology DNA synthesis platform space; ARK's partial reduction may reflect a cautious assessment of its current commercialization pace.

$Advanced Micro Devices (AMD.US)$ Reduced holdings by 34,643 shares. While AMD has performed actively in the AI GPU market recently, facing Nvidia's strong competitive advantage, ARK's slight reduction is likely a rebalancing of AI hardware positions within the portfolio, coinciding with an increased position in Broadcom.

$Brera Holdings (SLMT.US)$ Reduced holdings by 28,549 shares. Brera Holdings is a sports club holding company with relatively low alignment with ARK's core theme of disruptive innovation; the reduction may be an adjustment to enhance portfolio focus.

$CareDx (CDNA.US)$ Reduced holdings by 27,486 shares. CareDx focuses on genomic monitoring post-organ transplantation; ARK's slight reduction is likely a rebalancing move within the precision medicine sector.

$Palantir (PLTR.US)$ Reduced holdings by 18,056 shares. With Palantir's stock price showing strong performance recently, ARK's slight reduction may be for portfolio concentration management to prevent any single holding from becoming overly dominant.

$Illumina (ILMN.US)$ Reduced holdings by 15,613 shares. As the global leader in gene sequencing equipment, Illumina has seen continuous position adjustments by ARK, which may reflect a reassessment of its growth prospects or a rotation of capital into other genomics sectors.

$AtaiBeckley (ATAI.US)$ Reduced holdings by 2,670 shares. The small scale suggests this is likely a routine portfolio management action.
