SanDisk Sinks 5.6% as Rate Jitters and a Chinese DRAM Story Hit the Wrong Target
Published on 10/15/2026 at 15:31 | Editorial boerse-global.de
SanDisk shares came under heavy pressure on Thursday, sliding 5.6% to EUR 1,190.00 from a prior close of EUR 1,260.00, as a wave of risk aversion swept through semiconductor names on both sides of the Atlantic. The trigger was macro, not company-specific: hotter-than-expected US consumer prices for September, with headline inflation at 3.7% year-on-year and core inflation at 2.6%, both above consensus forecasts.
That reading hardened expectations on interest rate futures that the Federal Reserve will keep policy tight for longer, a headwind that hits capital-intensive growth industries hardest. The sell-off began on Wall Street, where technology stocks led the declines, according to AP, then rippled into Asian tech and chip shares during the following session. Lingering doubts about whether the enormous spending on artificial intelligence can be sustained added to the gloom.
A Sector-Wide Dragnet
Memory producers were pulled into the downdraft indiscriminately. As Reuters noted, pointing to losses among leading US memory names, investors have spent recent days treating storage makers as a single bloc. SanDisk, whose core business is NAND flash, has been caught in that net alongside DRAM-focused peers.
Part of the unease traces back to China, where ChangXin Memory Technologies (CXMT) has unveiled a new 4F² architecture for DRAM memory modules, stoking fears of oversupply and a collapsing price cycle across the memory industry. Yet CXMT concentrates on DRAM and does not produce NAND flash chips at all — precisely the segment that constitutes SanDisk's main business. On that reading, the market is penalizing SanDisk for a technological announcement from a competitor operating in an entirely different part of the market.
Should investors sell immediately? Or is it worth buying SANDISK?
Nor is it settled when China's technology can actually be manufactured at competitive yields in volume. BMO expects the global NAND market to remain undersupplied through 2027, which makes the leap from short-term DRAM excitement to SanDisk's flash economics a questionable one.
Long-Term Contracts and a $150 Billion Opportunity
While the market prices in abstract threats, SanDisk has been posting concrete commercial wins. The company is supplying certified microSD Express cards and USB-C storage media for a headset launch scheduled for spring 2027. Reuters reported in July 2026 on an estimated multi-year NAND supply agreement between Meta and SanDisk worth USD 42 billion.
Goldman Sachs, meanwhile, considers SanDisk well positioned to participate in the global AI memory market, which the investment bank values at USD 150 billion. Management, for its part, sees the long-term fundamentals of the storage business intact, even as technological advances on the supply side reshape the economics of the entire flash market.
Two Weeks to the Real Test
SanDisk now trades 42% below its 52-week high, a gap that largely reflects investor skepticism ahead of the company's next earnings report. The firm will publish results for the first quarter of fiscal 2027 on October 29, 2026, with an analyst and investor call scheduled for 1:30 p.m. Pacific time.
Until then, the share price is likely to take its cues from the broader rate mood and macroeconomic signals out of the US markets. For investors weighing whether the current selling wave has overshot, the October 29 report should offer a clearer picture of how resilient the underlying business really is — provided demand for fast flash memory holds and the multi-billion-dollar contracts keep the order book anchored.
