AMD closed at $519.85, down -5.76% from the prior session's $551.63, swept up in a broad semiconductor rout during regular trading hours. The selloff was triggered by South Korea's KOSPI index plunging 10% and SK Hynix slowing its HBM4 memory expansion, sparking fears of cooling AI infrastructure demand.
Micron Technology is set to report fiscal third-quarter 2026 results after market close on June 24, 2026. Analysts expect strong year-over-year growth driven by demand for high-bandwidth memory in data centers and AI applications.
Tower Semiconductor (TSEM) shares are falling approximately 11% in Tuesday's premarket session, pulling back from Monday's closing price of $316.85 to approximately $282.00. The primary catalyst is a sweeping global semiconductor sector rout: the iShares Semiconductor ETF is down approximately 5.9% in premarket, dragging the entire chip complex sharply lower.
Advanced Micro Devices (AMD) shares are falling approximately 5.28% in Tuesday's premarket session, pulling back from Monday's closing price of $551.63 to around $522.50.

AVGO shares declined approximately 6.6% over the last 30 days, closing at $392.91 on June 17, 2026, as post-earnings selling pressure offset robust AI demand signals. Q2 FY2026 results delivered record revenue of $22.19 billion (up 48% year-over-year) and AI semiconductor revenue of $10.8 billion (up 143% YoY), yet the stock sold off sharply when full-year AI guidance was reiterated rather than raised.
