Sector News
Crypto and biotech themes drove ARKK this week. Trump hosted crypto industry leaders, and bitcoin broke through $77,000, lifting Coinbase and Robinhood. Tempus AI surged on multiple sessions after BTIG raised its target price and mRNA vaccine news provided a further catalyst. Twist Bioscience gained 22.79% for the week despite a short report from Scorpion Capital, as Anthropic named it the independent evaluator for AI-designed protein testing. Tesla also contributed: its Robotaxi went fully unsupervised in Austin, and the Semi electric truck was confirmed for a European launch, pushing the stock up 6.02%.
The Week Ahead
On Tuesday (Aug 25), the US releases FHFA house price data, the Case Shiller 20-city index, the Richmond Fed composite index, consumer confidence, and new home sales. Housing and confidence figures will offer a cross-check on the rate path and growth outlook. Stronger-than-expected prints could reinforce hawkish Fed expectations, weighing on growth-stock valuations.
In Short
ARKK pushed higher against a weaker tape this week, helped by easing crypto regulatory fears and stock-specific catalysts in biotech and EVs. On the latest trading day, large-lot money was a net seller while small and medium orders were net buyers, pointing to a split between retail enthusiasm and institutional caution. The focus now shifts to next week’s economic data and whether the momentum in key holdings can hold through what may be a rates-sensitive stretch.
