# Why SanDisk (SNDK) rose 12.75% on August 14, 2026

SanDisk (SNDK) rose 12.75% on August 14, 2026 — SanDisk lifts revenue forecasts, sparks memory rally.

## What happened

SanDisk raised long-dated revenue-growth forecasts at its Investor Day, signaling confidence in decade-long secular demand for NAND flash memory.

## Why it moved

Higher multi-year growth guidance re-rates the stock by extending visibility into margin expansion and capital returns — memory investors had feared demand saturation, but management's bullish outlook reverses that…

## Why it matters

The AI Memory theme hinges on NAND and DRAM supply tightness powering pricing — SanDisk's upward guidance suggests pricing discipline will persist, validating the cycle rather than rolling it back.

## What would break the thesis

If management later trims guidance or NAND spot prices deteriorate despite the bullish posture, the re-rating unwinds sharply.
