SanDisk shares fell 7.2% on Friday, closing at EUR 1,160.00 as a broad semiconductor selloff swept the sector. The retreat had nothing to do with company-specific news. Instead, it reflected a wider reassessment of artificial intelligence spending and a fresh inflation print that rattled rate-sensitive growth names.
According to the Associated Press, mounting skepticism about the durability of massive AI infrastructure outlays weighed on chipmakers throughout the session. A hotter-than-expected September US consumer price index added to the pressure, pushing bond yields higher, while profit-taking ahead of the upcoming earnings season compounded the drag. Memory and storage producers bore the brunt of the damage, with Micron and SK Hynix also losing ground.
The unease had been building for days. Reports that China’s CXMT had achieved advances in denser memory cell designs stoked competitive fears, and Reuters reported that storage-linked names led losses among US semiconductor stocks earlier in the week. SanDisk was explicitly named among the affected companies.
A NAND Franchise Caught in a DRAM Narrative
Not every selloff tells the whole story. CXMT’s reported progress centers primarily on DRAM and planned products for AI data centers, whereas SanDisk’s core operating strength remains in NAND flash. The competitive threat that triggered the memory-wide de-rating therefore barely touches the company’s main franchise — a distinction the market appeared to overlook as it punished the entire sector indiscriminately.
The company’s own product cadence offers a counterpoint to the gloom. On Tuesday, SanDisk unveiled its Guardian Series of microSD cards, built for continuous recording in dashcams and surveillance cameras and available in capacities from 32 to 512 gigabytes through selected retailers. The launch highlights a business that is not solely hostage to the volatile capital-spending cycles of hyperscalers, but serves established consumer and security segments as well.
Should investors sell immediately? Or is it worth buying SANDISK?
Management’s longer-range view is decidedly more bullish than the current tape. On October 7, SanDisk’s Vice President of Market Intelligence projected in a company commentary that the global flash memory market would exceed USD 300 billion in 2026, with a figure approaching USD 500 billion in 2027. The same commentary addressed conditions in the NAND market, flash demand, and shipment volumes — a signal that leadership is tracking the cycle and positioning accordingly.
Wall Street Sends Mixed Signals
Analysts have split on the stock. Zacks Research upgraded SanDisk from “Hold” to “Strong Buy” on Tuesday. Weiss Ratings moved the other way a day later, cutting its rating from “Buy (B-)” to “Hold (C+)” on Wednesday. The divergence captures the tension between near-term macro headwinds and long-term growth promises.
Friday’s close leaves the shares 44% below their 52-week high — a painful reminder of how sharply the segment can swing. Hard evidence on the operating reality will not arrive until October 29, when SanDisk reports results for the first quarter of fiscal 2027 at 1:30 p.m. Pacific time. That call gives management its stage to disclose actual flash demand and, with concrete figures, to counter the doubts now swirling through the market.
