Cathie Wood's ARK Innovation ETF (ARKK) pulled in more fresh capital than the Invesco QQQ Trust in a single week, marking a notable shift in investor risk appetite. ARKK recorded a single-day inflow of $138 million, while the broader thematic equity category saw nearly $960 million in outflows during the same period.

ARKK's concentrated portfolio focuses on disruptive innovation in genomics, autonomous vehicles, fintech, and artificial intelligence. It also serves as a proxy for the digital asset space through holdings in Coinbase and Block, benefiting from improved crypto sentiment.

Despite its resurgence, ARKK manages roughly $6 billion to $6.5 billion, down from $27 billion at its 2021 peak. The fund remains highly concentrated, with any single name capable of dragging down the entire portfolio.
