Arm Holdings (ARM) shares rose 13.98% to $206.87, driven by renewed strength in the server CPU market. UBS noted that server CPU strength persists as AMD and Arm gain share, a narrative that helped reverse a recent decline.
What Happened
The stock rebounded sharply after falling 11.9% over the previous eight sessions, moving from $205.97 to $181.49. The primary catalyst appears to be the continued adoption of Arm-based processors in data centers, with reports indicating that Google’s new TPU 8i Max utilizes Arm-based Axion CPUs to manage AI workloads. This development underscores the expanding role of Arm architecture in high-performance computing environments.
While earlier reports mentioned rising volatility and options activity, the latest session showed a decisive shift toward bullish sentiment. The company’s market capitalization stands at $199.3 billion, with a trailing twelve-month revenue growth rate of 23.8%.

Volume was 3.2 million shares, which is 0.6 times the three-month daily average. The stock currently trades at a price-to-earnings ratio of 206.6, with a net margin of 17.1%.
