# Why SK Hynix (ADR) (SKHY) fell 5.19% on October 7, 2026

SK Hynix (ADR) (SKHY) fell 5.19% on October 7, 2026 — Trump's 300% tariff threat hits Korea stocks.

## What happened

Trump threatened tariffs up to 300% and explicitly pressured Korea over US investment commitments, prompting foreign investors to dump Korean mega-cap stocks—SK Hynix fell 5.2% alongside the broader regional selloff.

## Why it moved

SK Hynix's HBM and memory chips face tariff exposure via US sales and supply-chain complexity; tariff risk also cools capex outlook and weakens the won, compressing earnings guidance and multiples.

## Why it matters

Korea Tech rode an AI tailwind (memory demand, high-end chip demand), but tariff threats expose the dependence on open US markets and fracture the narrative of sustained, tariff-free growth.

## What would break the thesis

If the White House exempts semiconductor supply chains or offers a carve-out for strategic allies, SK Hynix could recover; conversely, if tariffs actually hit, memory pricing and capex plans collapse.
