Sandisk and Micron Extend Losses as AI Chip Boom Faces Dual Threat of Chinese Competition and Spending Doubt

The Quick Take

• Memory chip stocks Sandisk and Micron continued falling Tuesday as AI financing sustainability concerns spread among institutional investors
• Chinese DRAM producers accelerating capacity — rather than any single company event — are driving the structural re-rating of memory valuations
• The multi-week selloff in US and Korean memory producers has spread to European markets with German investors reducing AI hardware exposure
• Equipment maker ASML faces secondary risk as memory producers may defer capacity expansion orders amid the demand uncertainty

The German-market coverage of the global memory chip selloff reflects how deeply the AI semiconductor trade has penetrated European institutional portfolios. Sandisk and Micron — both US-listed memory producers — are at the epicenter of a correction that began with concerns about Chinese DRAM producers threatening the premium pricing model Korean and US memory makers have relied on to justify their elevated valuations through the AI boom cycle of 2025 and 2026.

European investors with positions in AI-linked semiconductor ETFs, including those traded in Frankfurt and on Euronext, face direct NAV impact from the continued Sandisk and Micron declines. The selloff creates a ripple into ASML — the Dutch equipment maker whose extreme ultraviolet lithography machines underpin advanced chip production — as investors question whether Korean and US memory makers will delay capacity expansion orders that had been a key pillar of ASML's multi-year revenue visibility.

The key forward signals are quarterly earnings from Micron and SK Hynix, expected within weeks, where management commentary on order books and pricing trends will either confirm or counter the bear thesis driving this selloff. The structural wildcard is China's CXMT DRAM production scale — independent industry analyses of its yield rates and capacity will determine whether the competitive threat materializes on a 12-month or 3-to-5-year timeline, a distinction that matters significantly for how deeply memory valuations ultimately reprice from current levels.
