ARK has been systematically reducing its Taiwan Semiconductor stake across multiple trading sessions.Taiwan Semiconductor Manufacturing Company Limited, TSMARK additionally offloaded 11,510 Advanced Micro Devices shares worth approximately $5.1 million. This move extends a consistent pattern of diminishing AMD holdings that has unfolded throughout the previous week across ARK’s portfolio of funds.Teradyne represented another semiconductor-connected holding ARK retreated from. The firm liquidated 22,576 shares with a market value near $8.2 million. This follows previous Teradyne disposals, indicating a calculated withdrawal from the position.Beyond semiconductors, ARK divested stakes in three additional companies.

The firm secured 105,616 shares distributed between two exchange-traded funds — the ARK Innovation ETF and the ARK Next Generation Internet ETF — representing a total investment of $4.85 million.Cerebras operates as an artificial intelligence semiconductor company recognized for manufacturing wafer-scale processors engineered specifically for AI inference operations. The organization established its IPO pricing at $185 per share on May 13. Market demand reportedly exceeded available shares by more than twenty-fold.When Cerebras stock commenced public trading on May 14 under ticker symbol CBRS, shares launched at $350. The equity concluded its inaugural trading session at $311, maintaining substantial premium over the offering price.This opening-day performance propelled Cerebras to an estimated valuation approaching $49 billion. The enterprise has captured investor interest through its collaboration with OpenAI and strategic alliance with Amazon Web Services.Understanding ARK’s Portfolio Management PhilosophyThe theme underlying Thursday’s transactions is transparent. ARK liquidated holdings in enterprises experiencing robust recent valuation expansion, including Taiwan Semiconductor at its historical peak, while channeling new capital toward an emerging, accelerated-growth opportunity.This methodology aligns with ARK’s established history of transitioning away from appreciated securities and into early-phase companies operating within rapidly-evolving technology sectors.Cerebras matches this investment thesis. The AI chip space has captured substantial capital deployment as requirements for data center infrastructure expand. Cerebras occupies a strategic position within this movement, having established genuine commercial partnerships.These transactions were revealed through ARK’s daily portfolio transparency reports, which the organization releases following each market close. As of May 14’s conclusion, Cerebras registered among the most successful IPO launches within the AI hardware sector in recent history.The post ARK Invest Offloads TSMC (TSM) at Peak, Snaps Up Cerebras After Stellar Market Debut appeared first on Blockonomi.
