Amkor, Himax, Teradyne, and Penguin Solutions shares are soaring, what you need to know
What happened?
A number of stocks jumped in the morning session after specialized cloud provider CoreWeave lifted its annual sales forecast, alleviating concerns over cooling artificial intelligence hardware demand.
CoreWeave said in its quarterly release that third-quarter revenue surged 168% year-over-year to $3.66 billion, while its order backlog expanded to $132.5 billion. The company raised its 2026 revenue outlook to between $13.0 billion and $13.3 billion, ahead of the $12.9 billion consensus compiled by Reuters, and lifted capital expenditure plans to between $37 billion and $39 billion. The update alleviated credit market fears that debt-fueled data center buildouts would stall.
In research cited by CNBC, JPMorgan credit analysts noted that expanding operating cash flow and a targeted inflection to adjusted profitability in 2028 resolve immediate funding overhangs. With CoreWeave utilizing customer prepayments rather than new debt to fund expansion, hardware delivery schedules remain intact. For chipmakers, cloud capital spending directly underpins forward silicon demand. When infrastructure operators demonstrate that contracted leasing demand can fund physical deployment, it protects order books and pricing power across advanced processor and memory suppliers.

Zooming in on Amkor
Amkor’s shares are extremely volatile and have had 75 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.
The previous big move we wrote about was 5 days ago when the stock gained 5.3% on the news that dip-buyers moved into beaten-down semiconductor and hardware names following the sector's steepest one-day rout in 19 months.
The turnaround gained traction after President Donald Trump wrote on Truth Social that he is 100% in favor of artificial intelligence infrastructure, calling data centers "GOLD" and pledging to help states expand capacity, in comments carried by CNBC. That endorsement eased worries ignited by Democratic midterm victories and calls for data-center project halts.
Amkor is down 11% since the beginning of the year, and at $38.18 per share, it is trading 59.2% below its 52-week high of $93.55 from June 2026. Despite the year-to-date decline, investors who bought $1,000 worth of Amkor’s shares 5 years ago would now be looking at an investment worth $1,653.
