Goldman: $738B memory stock wipeout after CXMT 4F² reveal was overreaction
zephyr_z9 · x · 2026-10-17
Per Goldman Sachs, global memory suppliers lost a combined $738B in market cap in the two weeks after CXMT's October 2026 4F² architecture disclosure: SK Hynix -25%, Samsung -20%, CXMT -15%, Micron and SanDisk -11%. Goldman views the reaction as overestimating the Chinese breakthrough. Physical fundamentals diverged sharply—DDR5 16Gb spot pricing climbed from $54.50 past $60.00 over the same sell-off window. The poster argues the drawdown had little to do with the disclosure itself.
