On September 21, ARM Holdings rose 6.58% in regular trading, trading at $303.42/share, with turnover of $319 million. The rally was fueled by a confluence of positive catalysts centered on parent company SoftBank and management confidence in AI-driven growth.

SoftBank Group has increased a margin loan collateralized by Arm shares by $5 billion to $25 billion, renegotiating terms with creditors this month. This marks the third time SoftBank has expanded its Arm-backed borrowing facility, underscoring its strong conviction in Arm's value as it scales AI investments. Meanwhile, Arm CEO Rene Haas expressed growing confidence in the company's AGI CPU achieving a $2 billion revenue target, noting continued improvement in supply lock-in capabilities. Arm had initially projected $1 billion in revenue from its custom CPU at launch in March, with Meta as its first client, before demand doubled to $2 billion as disclosed during the May earnings call.

Within the Semiconductors sector, Intel surged 9.21%, Advanced Micro Devices rose 4.83%, Micron Technology gained 3.04%, while NVIDIA edged down 0.03% and Broadcom slipped 0.71%.
