# Why SK Hynix (SKHX) fell 8.18% on August 6, 2026

SK Hynix (SKHX) fell 8.18% on August 6, 2026 — AI Memory selloff pulls Asian tech lower.

## What happened

SK Hynix plunged 10% as Wall Street AI stocks sold off and the de-risking cascaded into Asian tech; the move was a pure sympathy decline following U.S. equity weakness.

## Why it moved

SK Hynix dominates HBM supply for AI servers and carries heavy leverage to U.S. AI capital intensity; when Wall Street sentiment turns, foreign institutional flows reverse and Seoul follows immediately.

## Why it matters

The Korea Tech thesis rests on HBM's near-monopoly in next-gen AI servers, but a three-month selloff now reflects oversupply and margin-compression fears as new capacity ramps; SK Hynix is the canary in that coalmine.

## What would break the thesis

A stabilization or rebound in U.S. semiconductor stocks would likely reverse the Seoul selloff; watch for any hints of demand disappointment from hyperscaler earnings or capex cuts.
