AMD stock fell 4.27% on Tuesday amid a global market selloff. The dip is linked to a 5.8% drop in South Korea’s KOSPI index, erasing $235 billion, and rising tensions between the US and Iran. Bond yields climbed and inflation concerns persist, with CPI at 3.4% in July. Analysts remain bullish on AMD due to AI growth and upcoming Helios chips, though short-term volatility is expected.
Advanced Micro Devices, Inc (AMD) stock price closed 4.27% lower on Tuesday, August 18, 2026, and fell an additional 0.39% in pre-market trading. The decline comes amid a broader global market selloff.
South Korea’s KOSPI index fell 5.8%, erasing nearly $235 billion from the stock market. According to a report, “South Korea’s KOSPI closed down 5.8%, wiping out around $235 BILLION from the market. Samsung Electronics closed down 7.82%, while SK Hynix sank 9.75%, erasing roughly $174 BILLION.”
The broader semiconductor dip also follows elevated tensions between the US and Iran. The Middle East conflict has increased investor worry as oil prices pressure the global economy. Bond yields have climbed to multiyear highs, raising questions about borrowing costs and inflation.
Consumer Price Index (CPI) figures in the US dipped in July 2026 to 3.4%. However, the ongoing conflict could lead to inflation gaining steam next month. The Federal Reserve might choose to raise interest rates to combat rising costs, which could cause further volatility for AMD stock.
AMD remains one of the largest beneficiaries of the AI boom, with revenue showing massive growth over the past year. The company’s Helios chips are expected to roll off shelves, with sales reflected in the Q4 earnings report. Analysts are bullish on AMD’s future, though short-term risks persist.
