Nomura issued a bullish call on an AI-driven memory supercycle and materially raised its price targets on Samsung Electronics and SK Hynix, citing sustained HBM demand and tightening DRAM/NAND supply. The upgrade reinforces the bull thesis for Korean memory leaders and is likely to support sentiment across the HBM supply chain into 2H26.

Why it matters: Major sell-side target hike on both Korean memory leaders tied to an explicit AI/HBM supercycle call is a direct, near-term catalyst for the two largest names in the coverage universe.

Korean semiconductor names are being positioned as the principal beneficiaries of accelerating global AI infrastructure buildouts, with both memory (HBM/DDR5) and foundry segments showing a cyclical rebound that is pulling forward capex and order visibility. The piece frames Samsung and SK Hynix as the core plays, with positive read-through to packaging/equipment suppliers tied to HBM ramp.

Why it matters: Sector-wide weekly recap on AI-driven memory/foundry rebound — directionally bullish for K-semis but no specific policy event, earnings print, or contract that warrants 'high'.

The US Trade Representative said semiconductor export controls are not a main agenda item in upcoming US-Korea trade talks, tempering expectations of near-term policy shifts. The remark suggests the existing US chip export control regime targeting China remains intact, with no imminent easing or tightening tied to these negotiations. Neutral-to-slightly-positive for Korean memory and equipment names that had feared additional restrictions.

Why it matters: USTR comments on export controls are sector-relevant for Korean chipmakers and equipment suppliers, but the message is that nothing changes near-term, limiting direct trading impact.
