Memory Semiconductor Stocks Hit Longest Losing Streak Since 2008

Memory semiconductor stocks have declined 19% from their September peak, marking the longest losing streak for the chip index (SOX) since 2008. The downturn is driven by deepening investor concerns regarding future supply growth and intensifying competition within the artificial intelligence infrastructure sector.

Despite the volatility, UBS analysts maintain a positive outlook for the sector. The investment bank cites strong demand for high-bandwidth memory (HBM) used in AI accelerators, solid-state drives, and conventional server memory. UBS identifies Samsung Electronics as its top pick and projects that HBM shipments will grow 49% year-on-year by 2027.

Analysts acknowledge market risks, including potential capacity expansions by Samsung Electronics and technological advancements at China's ChangXin Memory Technologies. However, UBS argues these factors are unlikely to materially disrupt industry supply and demand before late 2028. Additionally, demand is strengthening for system-on-chip memory modules produced by Nvidia Inc.
