On September 29, ARM Holdings rose 3.01% in pre-market trading, trading at 291.01 USD/share, with turnover of approximately $37.24 million. The rebound follows a sharp selloff in the prior session when the stock plunged over 8%, dragged down by broad weakness across the semiconductor and AI sectors.

The previous session's decline was triggered by OpenAI's announcement that it would pause training and testing of its most advanced AI model, which rattled investor sentiment around AI infrastructure spending and chip demand. ARM was among the hardest hit, falling as much as 9.77% on September 28, while the Philadelphia Semiconductor Index dropped 3%. On September 29, the broader chip sector showed signs of recovery, with Broadcom up 2.14%, Micron Technology up 2.02%, AMD up 1.51%, NVIDIA up 0.93%, and Intel up 0.71%, suggesting a technical rebound from oversold conditions.
