SanDisk (SNDK) shares rose 6.2% on Monday, November 9, 2026, outpacing a 2.3% gain for the S&P 500. The company released no announcements, earnings reports, or filings around the move. The stock climbed as Wall Street rebounded from a steep sell-off in global technology shares the week before. So what ties a memory-chip maker to a rebound in technology stocks?
SanDisk Sells More And More Into AI Data Centers
SanDisk is tied to technology stocks through AI data centers, its fastest-growing business. In fiscal Q1 2027, which ended October 2, 2026, data center revenue was $4.8 billion, up 61% from the quarter before. The larger Edge business, where management cited strong growth with automotive customers, grew 7% from the quarter before.
During the October 29 call, management said the company’s data center partners include three U.S. hyperscalers, the large cloud operators. Management also described a structural increase in NAND demand, driven particularly by AI.
SanDisk has moved with technology stocks in both directions in November 2026. Memory stocks took the heaviest losses in the chip sell-off on Thursday, November 5, and SanDisk led them down with a 22.3% fall. On Monday, technology stocks rebounded and SanDisk climbed with them, as the Nasdaq Composite rose 2.7%.
SanDisk Rose Along With Memory And Storage Stocks
SanDisk moved with its group rather than on its own. Every company on its peer list rose on November 9, among them Micron Technology, up 6.3%, and Western Digital, up 9.9%. The list has five companies. The other three are Seagate Technology, up 9.8%, Hewlett Packard Enterprise, up 6.2%, and NetApp, up 4.1%. SanDisk’s gain was close to Micron’s and smaller than Western Digital’s, but it beat the technology sector fund XLK, which gained 3.7%.
Where SanDisk Stock Stands After A Steep Month
Daily gains of this size are common for SanDisk. The stock recorded 50 daily gains at least this large in the prior 365 days, and its latest move of this size in either direction was the November 5 fall.
Over twelve months the stock returned 326.8%, compared with 13.7% for the S&P 500. Shares reached their highest close of the year at $2,335 on June 25, 2026. In the past month alone, SanDisk lost 44.0%, while the S&P 500 fell 3.3%. That left the November 9 close of $886.51 far below the June high, though well above the year’s lowest close of $194.38 on December 3, 2025.
At that close, SanDisk traded at 4.5 times its sales over the last twelve months, against 3.1 times for the S&P 500. The company is expected to report its fiscal second-quarter 2027 results in January 2027, and data center revenue is the measure to watch.
