On July 21, ARM Holdings rose 6.08% in regular trading, trading at 283.846 USD/share, with turnover of $80.35 million.

On the news front, the semiconductor sector extended a collective rebound following a period of consecutive pullbacks, with systematic sector buying lifting ARM in tandem. Among peers, Micron Technology rose 7.33%, SK Hynix gained 6.92%, Intel advanced 6.40%, and Advanced Micro Devices climbed 4.62%. ARM had previously retreated over 20% from its highs after HSBC downgraded the stock from Buy to Hold on July 14, citing elevated valuations and wafer foundry capacity bottlenecks constraining near-term earnings release. UBS subsequently lowered its ARM target price from $470 to $360 while maintaining a Buy rating, reflecting continued institutional conviction in the company's long-term growth thesis despite near-term headwinds. The broad-based sector recovery suggests technical buying and mean-reversion flows are driving the current rebound.
