Seagate and Western Digital Shares Slide Amid China Tech News and Broadcom Warning
Yahoo Finance ·
Shares of major memory and semiconductor providers faced significant downward pressure during the morning session on October 13, 2026, driven by fresh design breakthroughs in China and cautious remarks from industry leadership. ChangXin Memory Technologies announced plans to launch 4F-square DDR5 server modules by late 2026, expanding memory density by one-third and arriving roughly two years ahead of Samsung's projected roadmap. This development caused investors to re-evaluate whether tight artificial intelligence memory supplies might ease earlier than anticipated. Furthermore, Broadcom CEO Hock Tan expressed concerns regarding speculative artificial intelligence spending, comparing current market fervor to casino gambling during an event in Singapore. Consequently, sector sentiment weakened, sending Seagate down 4.5% and Western Digital down 4.7%. Western Digital shares trade at $370.61, remaining 50.3% below its 52-week high of $746.23 from June 2026, though up 97.5% year-to-date.
AI 시장 분석
Memory semiconductor stock prices plummeted after China's CXMT announced plans to launch 4F-square DDR5 server modules by the end of 2026, two years ahead of Samsung Electronics. Additionally, Broadcom CEO Hock Tan compared the AI investment frenzy to casino gambling, exacerbating market concerns. As a result, major memory-related stocks such as Seagate (STX) and Western Digital (WDC) experienced sharp declines.
상승 영향
- Semiconductors — Some stocks (such as AVGO) showed a differentiated trend, rising slightly due to expectations of AI-related benefits regardless of the Broadcom CEO's remarks.
하락 영향
- Semiconductors — Pressure for memory oversupply and margin contraction emerged due to the early release of 4F-square DDR5 by China's CXMT and concerns over an AI investment bubble.
DYAX 전담 분석
Downward pressure was exerted across the memory semiconductor sector due to CXMT's technological innovation and oversupply concerns, deepening the stock price declines of STX and WDC. Short-term earnings expectations retreated as AI investment bubble theories overlapped, but future mass production schedules and earnings reports should be monitored to see if excessive concerns subside.
The bullish scenario is that China's mass production schedule is delayed, allowing the existing supply shortage to persist and AI hardware demand to be sustained, while the bearish scenario is that oversupply and margin pressure materialize, deteriorating earnings. Key monitoring indicators are the shipment volumes and price trends of major memory manufacturers.
