AMD stock declines amid global market sell-off and South Korean crash

AMD stock volatility semiconductor market South Korean market crash AI chip demand global market sell-off

Advanced Micro Devices (AMD) stock experienced a decline of 4.27% on August 18, 2026, following a broader global market sell-off. This volatility coincided with a significant downturn in the South Korean market, where the KOSPI index fell 5.8%, erasing approximately $235 billion in value. Major semiconductor players in South Korea, including Samsung Electronics and SK Hynix, saw substantial losses of 7.82% and 9.75% respectively.

Despite recent market volatility, AMD has seen significant growth driven by the artificial intelligence sector. The company reported a 107% year-over-year increase in data center revenue for Q2, reaching $6.7 billion. AMD management anticipates the total AI compute market could grow to $2 trillion by 2030, with the data center accelerator market projected to reach $1.4 trillion by the end of the decade.
