On July 16, ARM Holdings declined 3.06% overnight, trading at $268.52/share, with turnover of $2.99 million.

The decline extends the ongoing selloff triggered by HSBC's downgrade of ARM from Buy to Hold earlier this week. Although the bank simultaneously raised its target price from $255 to $315, it explicitly noted that ARM's stock had surged 122% since the March Arm Everywhere product launch, far outpacing the Philadelphia Semiconductor Index's 57% gain over the same period, indicating that current valuations have fully priced in long-term growth expectations. The report also flagged global wafer foundry capacity bottlenecks as a core constraint limiting near-term profit realization for ARM's server CPU business.

The semiconductor sector continued to face broad selling pressure overnight, with Micron Technology down 1.75%, NVIDIA down 0.90%, AMD down 0.76%, and Intel down 0.68%, amplifying ARM's pullback.
