AI Overview
What happened: Key chipmakers, including Micron (MU), Broadcom (AVGO), and Marvell (MRVL), experienced significant premarket losses. MU fell 5% on Monday, while AMD and Lam Research each dropped over 4%. Micron plummeted 12.3% on Thursday, and along with SanDisk and Western Digital, they all reversed from record highs on Tuesday. The PHLX Semiconductor Index (^SOX) tested the 12,000 area, a crucial support level, after a $2 trillion sell-off. On Friday, Micron, SanDisk, and Marvell shares slid, with Micron down 11% and SanDisk down 14%. Asian tech stocks followed suit, with Samsung Electronics falling nearly 7%.
Market impact: The sell-off was driven by a combination of factors, including softer guidance from Broadcom, a strong jobs report, and a rotation out of AI-linked names. The entire memory and chip equipment complex was dragged lower by SK Hynix's HBM pricing cut. The sell-off was concentrated among high-flying names, with Micron, up ~243% year-to-date, leading the decline. The weakness was particularly pronounced in South Korea's chip-heavy market.
What to watch next: Micron's earnings release on June 28 will provide crucial insights into the memory market dynamics. Investors will also closely monitor the PHLX Semiconductor Index's (^SOX) 12,000 support level, as a break below could signal a more significant breakdown. Additionally, the broader market's performance, particularly the S&P 500 and Nasdaq Composite, will influence the semiconductor sector's trajectory.
