Memory Volatility Without a New Company Announcement

Sandisk (NASDAQ:SNDK) was trading down 8.22% at USD 860.39 on Friday, November 13, 2026, in market data that is the figure of record for the live session only. No company announcement dated November 12 or 13 explaining the move was found. The company makes NAND flash memory and storage products. The shares have been extremely volatile: a published report said they closed at USD 806.43 on November 5, down 22.26% in an AI and chip selloff, and they fell again on November 10 after a research-firm report on NAND market share. The stock has also slid on days of strong results. In market data, several AI-infrastructure and memory names were among the day's decliners, which fits a group move but does not prove a shared cause.

Record Quarter, Sharp Guidance and the 8-for-1 Split

Sandisk reported fiscal first-quarter results for the period ended October 2 on October 29, 2026. Revenue was USD 11.0 billion, up 23% sequentially, and adjusted earnings were USD 49.51 a share. Data Center revenue was USD 4.8 billion and Edge Computing revenue USD 5.8 billion, per a published report. Guidance for the next quarter is revenue of USD 12.4 billion and adjusted gross margin of 85%. An 8-for-1 Stock Split was announced, and sources differ on the date: one report said the split takes effect November 19, another that post-split trading begins November 20. A split changes the share count and price, not the value of a holding, and investors should confirm the dates in the company notice.

Share Loss Data, Valuation Swings and What Could Reverse the Move

The November 10 report from a Market research firm said Sandisk's share of NAND flash revenue slid to 11% in the second quarter of 2026 from 13%, while a Chinese rival held at 14%. The 52-week range runs from USD 183.00 to USD 2,354.39, and market data showed a value near USD 133 billion on November 13. Published coverage tied the late-October fall to worries that AI Demand or memory prices could peak, and the broader chip selloff in early November to fears of tighter data-center rules. A hotter Inflation report followed on November 10. No November 13 driver was verified.

Where Things Stand

A new company announcement was not the cause on the evidence found. Sandisk (NASDAQ:SNDK) is down 8.22% in a stock that has swung by double digits in single sessions since late October, driven by memory-price worries, a NAND market-share report and AI-sector selling. The Business posted record revenue of USD 11.0 billion and guided higher, but expectations were already high. The 8-for-1 split arrives next week and is mechanical. Next markers are the second-quarter report and any change in memory pricing.
