X discussionSanDisk fell about 6% on Monday and kept sliding as China's CXMT unveiled denser 4F² DRAM progress and year-end DDR5 server plans. Traders are arguing whether a DRAM headline should punish a NAND flash name that is still up over 500% in 2026 and already roughly 37% off its June high near $2,354.
BullThe CXMT scare is overdone for SanDisk because the company primarily makes NAND flash, not DRAM. Announcing a denser cell is not shipping competitive yields at scale while AI memory demand stays short and JP Morgan just flagged multi-year contracted memory backlog across the group.
BearChinese capacity expansion threatens memory pricing power across the complex, and SanDisk is already paying for the repricing. The stock lost its 50-day moving average and is down about 15% in October after a parabolic AI run.

Bull evidence
@MelvinInvestsSelling SNDK on a DDR5 DRAM headline is questionable because SanDisk primarily makes NAND and CXMT still must prove scaled yields
@varuntakkar01Buy the dip in MU near $980 and SNDK near $1,470
@RealNickMugalliJP Morgan's new note is bullish on memory and storage, citing multi-year contracted backlog and sold-forward output for the group including SNDK
Bear evidence
@RedDogT3An SNDK sell signal got semis out Friday after the stock lost the 50-day moving average
