SanDisk shares tumble in pre‑market trading after hotter‑than‑expected U.S. inflation data

SanDisk Corp. fell about 5% in pre‑market trading on October 15, reaching roughly $1,335 per share after the September Consumer Price Index rose 3.7% year‑over‑year and core CPI increased 2.6%, exceeding expectations. The stronger inflation sparked fears of prolonged Federal Reserve tightening, pressuring rate‑sensitive chip makers. The sell‑off extended to peers Micron and SK Hynix, which also posted double‑digit pre‑market losses.

The price decline reflects heightened market risk for memory‑chip stocks ahead of SanDisk’s fiscal Q1 2027 earnings report on October 29, potentially increasing volatility and affecting investors’ short‑term positioning.
