Overview
- Major memory names including Micron, Samsung and SK Hynix and the Roundhill Memory ETF have each fallen more than 20% from recent closing highs, placing those names in bear-market territory.
- The sell-off has wiped about $1.5 trillion from a tracked basket of semiconductor stocks since June 25, with Micron alone losing roughly $350 billion in market value over that stretch.
- Samsung posted an outsized profit jump that did not stop the sell-the-news reaction, showing investors trimmed positions despite the company’s strong quarterly results.
- SK Hynix’s planned U.S. listing has shifted into a sentiment test for the sector, while a U.S. class-action suit filed on June 25 alleging coordinated production moves adds legal and regulatory risk.
- Analysts point to longer-term headwinds that could curb HBM pricing, including projected 2027–2028 capacity increases and growing competition from Chinese producers, even as the group still sits on a median gain near 60% since late March.
