On June 17, ARM Holdings rose 3.03% overnight, trading at $408.61/share, with turnover of $15.85 million.

The rally was driven by a broad surge across the semiconductor sector as geopolitical tensions eased following a US-Iran ceasefire memorandum of understanding. The war premium retreat reignited risk appetite, prompting traders to restart their pre-conflict playbooks heavily weighted toward AI computing infrastructure stocks. ARM, as the dominant instruction set architecture provider whose IP underpins most AI chip designs, directly benefits from tech giants' record-breaking trillion-dollar AI capital expenditure cycle.

Bank of America recently raised its price target on ARM from $245 to $335 while maintaining a neutral rating. The stock had already gained nearly 8% on June 12 and over 6% on June 11 as the semiconductor sector broadly re-rated higher. ARM's major shareholder SoftBank surged over 10% in Japanese trading as markets repriced AI-linked equities globally. Within the Semiconductors sector, Micron Technology rose 5.17%, Marvell Technology gained 4.22%, Intel advanced 3.35%, and AMD climbed 3.29%.
