On September 10, ARM Holdings fell 4.55% in regular trading, trading at 253.96 USD/share, with turnover of $67.40 million. The decline came amid a broad selloff across the semiconductor sector, compounded by short-term profit-taking following a roughly 7% rally over the prior two sessions.

On the news front, the pullback followed a strong run-up driven by the announcement that Samsung Electronics and Arm had formally launched a joint development project for edge-side AI chips. Arm reportedly approved one-time engineering expenses in late August for next-generation edge AI SoC development, with Samsung handling integration on its 2nm process node and OpenAI identified as a potential end customer. After cumulative gains of approximately 7% on September 8-9, profit-taking pressure intensified. Additionally, certain Wall Street analysts recently downgraded ARM, weighing on sentiment.

Notably, Piper Sandler initiated coverage on ARM with an Overweight rating on the same day, while the consensus analyst target price stands at $291.87, significantly above current levels. Within the Semiconductors sector, stocks broadly declined, with Micron Technology down 3.17%, SK hynix down 3.97%, Intel down 3.72%, Advanced Micro Devices down 1.65%, and NVIDIA down 1.26%.
