# Why Roundhill Memory ETF (DRAM) rose 5.30% on August 13, 2026

Roundhill Memory ETF (DRAM) rose 5.30% on August 13, 2026 — SanDisk's upbeat outlook buoys AI memory peers.

## What happened

The Roundhill Memory ETF rose 5.3% as SanDisk's raised decade-long growth guidance buoyed sentiment across the entire NAND and DRAM memory complex.

## Why it moved

SanDisk's confidence in pricing and demand trickles across the memory ETF's holdings via shared supply-chain mechanics — tighter inventory and sustained AI capex lift DRAM and NAND players together.

## Why it matters

The AI Memory theme relies on supply tightness sustaining HBM and DRAM premiums against skeptics who feared oversupply — SanDisk's bullish guidance is the catalyst that reverses that skepticism for the whole basket.

## What would break the thesis

A rapid shift to inventory gluts or margin compression across memory peers would undermine the ETF's consensus upside in weeks.
