Global AI and Chips Rally, US +9.24% and KR +5.34% Response

TL;DR

• US IT and semiconductor sector staged a strong rebound at +9.24%, and Korean IT and semiconductor sector also rose +5.34%. (collected: 2026-08-06 08:20 KST)
• On the previous session KOSPI and KOSDAQ closed at 6,598.26 (+3.76%) and 799.59 (+2.42%) respectively. Key at today s open is whether semiconductor and AI-related names extend gains and how flows behave.

What happened

Overnight US markets saw a tech-led rebound, with IT and semiconductor sector up 9.24%. Headlines include optimistic commentary on NVIDIA and AI chip demand, and sharp rallies in AI, adtech, and robotics names. That external impulse carried through to Korea, where the domestic IT and semiconductor sector responded with a 5.34% rise. On index terms, the confirmed close for August 5 was KOSPI 6,598.26(+3.76%), KOSDAQ 799.59(+2.42%).

By the numbers

• US sector: IT·semiconductors +9.24%, led by demand expectations for tech and chips
• KR sector (previous day): IT·semiconductors +5.34%, a chain reaction from overseas markets
• Indices (8/5 confirmed close): KOSPI 6,598.26 (+3.76%), KOSDAQ 799.59 (+2.42%)
• News flow: NVIDIA founder remarks (chip growth potential), sharp rallies in AI names (Palantir etc.), robotics upside, headlined stories explaining sector momentum.

PickStock checkpoints (what to confirm)

• Foreign and institutional flows: Check net buy/sell by foreigners and institutions after market open. It is crucial to see whether the global tech rally maps into domestic flows.
• Differentiation within semiconductors by subsector and market cap: Verify whether large AI chip beneficiaries move with parts and equipment suppliers, and whether sector averages translate into individual names.
• Earnings and supply notices: Confirm any overnight earnings or filings to assess event risk.
• Crypto and AI fund flows: Inflows or outflows from crypto funds and AI/tech ETFs can amplify sector volatility.
• Global rate and policy shifts: In poly markets, the market priced odds for an additional Fed hike ('No' bet 56%) and rate cut expectations ('No' 100%) can affect risk asset preference.

Today s session is about how quickly overseas tech and chip strength transmits to Korea, and how market participants react. Momentum is strong in the short term, but material risks remain and should be checked. See Chart Technicals for sector and name charts to locate supply-demand turning points.
