Arm Holdings Plc shares fell 4.46% to $310.79 on Wednesday as investors took profits across the semiconductor sector and reacted to broader macro pressures. The decline occurred despite the lack of company-specific negative news. Arm has gained over 190% year-to-date, significantly outperforming the S&P 500’s 8% return and the NASDAQ 100’s 16% return.

CEO Questions AI CPU Export Controls

Arm CEO Rene Haas commented that U.S. restrictions on AI CPU exports to China would be difficult to enforce. Haas noted that CPUs are widely used across many applications and cannot easily be tied to AI workloads. He told Reuters that regulators would struggle to set clear performance thresholds and memory bandwidth limits for CPUs, unlike NVIDIA Corp’s GPUs. "They would have to limit everything," Haas said, arguing that CPU restrictions would be much harder to implement than AI chip controls.

Arm’s CPU business is gaining attention as AI inference demand grows. Haas said Oracle Corp and China’s ByteDance have become new customers for Arm’s AGI CPU, which the company is positioning for next-generation AI systems.

Technical Analysis

From a trend perspective, ARM is still in a powerful uptrend. The stock is trading 3.4% above its 20-day SMA ($305.50) and remains far above its 50-day ($231.26) and 200-day ($159.19) SMAs. The 20-day SMA remains above the 50-day SMA, and the golden cross that formed in April continues to validate the longer-term trend.

Arm Holdings is the IP owner and developer of the Arm architecture, which powers 99% of the world’s smartphone CPU cores. It also holds a high market share in other battery-powered devices, such as wearables, tablets, and sensors.

Top ETF Exposure

Arm carries significant weight in several exchange-traded funds, meaning any significant inflows or outflows will likely trigger automatic buying or selling of the stock.
