KOSPI -5.46% Crash, Was Nvidia·iPhone·Crypto the Trigger?
KOSPI -5.46%!!!
If yesterday closed like this, this morning feels heavy.
Overnight headlines piled up and risk asset sentiment weakened.
Retail investors asked: "Is this another session where only large caps get crushed?"
Yes, large caps and tech are likely to react most sensitively.
Why did it fall so much, quick summary?
KOSPI 6,035.35 (-5.46%) [2026-10-13 final close]
KOSDAQ 837.03 (-1.43%) [2026-10-13 final close]
US sectors: IT and semiconductors -1.22% weakness among others (source: overseas market roundup)
Overseas drivers: iPhone18 demand worries at Apple, Nvidia and AI chip weakness, crypto ETF outflows
High sensitivity of large tech and semiconductors amplified the index decline.
ETF outflows mean money is leaving investment funds.
How big is the Apple issue?
Headline: Reports of weak iPhone18 demand and reduced Pro production (source: overseas press list)
Demand worries can spill over to Apple suppliers and domestic IT and parts stocks.
How does AI chip weakness connect to the Korean market?
Headline: Selling in Nvidia and other AI chips, early-week weakness in HBM-related names
AI chip and HBM supply chains link directly to domestic equipment, materials, and memory names.
What signal did crypto give?
Headline: Bitcoin ETF shows some inflows resuming but Ethereum ETF has 10 consecutive days of selling and net outflows (source: crypto ETF flows)
Volatility in crypto capital can shake risk asset preference.
Which stocks and sectors to watch first?
1) Large IT and semiconductors: check Nvidia and memory-linked reactions first
2) Apple suppliers and mobile parts: sensitive to iPhone supply news
3) Crypto-linked stocks and ETF-related names: can swing with capital flows
