Why the KOSPI broke 5,500 — closed at 5,469.47 on October 26, 2026 as foreigners sold ahead of a 'super week'
South Korea's KOSPI fell 80.83 points (1.46%) to 5,469.47 on October 26, 2026, losing the 5,500 level. Foreign investors net sold about 695.5 billion won for a second day, more than institutional buying of 611 billion won could absorb. Markets pointed to caution before October 28–29, when the Fed decision, Microsoft, Alphabet and Amazon earnings, and Samsung Electronics and SK Hynix results all land, plus worries about AI spending
The three lines

- Flows — foreigners net sold ~₩695.5B (2nd day); institutions +₩611B, retail +₩47.4B

There were buyers; there were just more people waiting. South Korea's benchmark KOSPI fell 80.83 points, or 1.46%, to 5,469.47 on October 26, 2026, giving up the 5,500 level and hitting what outlets describe as a six- or seven-month low. Foreign investors were net sellers for a second day, dumping roughly ₩700 billion (about $525 million at ₩1,323 per dollar). Institutions bought more than ₩600 billion and still could not hold the index. The tech-heavy KOSDAQ fell harder, down 3.26% to 727.21.
Brokers' explanations converge on one thing: this week brings a US rate decision, US big-tech earnings, and Samsung Electronics and SK Hynix results all at once. Selling to cut risk before seeing the numbers pulled the market down.
1. What happened on October 26
| Item | Value |
|---|---|
| KOSPI close | 5,469.47 (−80.83, −1.46%) |
| Intraday range | 5,455.11 – 5,565.67 |
| KOSDAQ close | 727.21 (−24.48, −3.26%) |
| Foreigners (KOSPI) | About ₩695.5B net sold, 2nd straight day |
| Institutions (KOSPI) | ₩611.0B net bought |
| Retail (KOSPI) | ₩47.4B net bought |
| KOSPI gainers / decliners | 101 / 792 |
| Won per dollar | 1,323.1 (won 1.5 stronger) |
Chip heavyweights lifted the index to 5,565 early before foreign selling grew through the afternoon. Decliners outnumbered gainers almost eight to one — a broad sell-off, not just a large-cap story.
2. Four reasons for the fall
| Cause | Detail | Evidence |
|---|---|---|
| ① Foreign selling | Net sellers two days running, ~₩700B on Oct 26 | About ₩18 trillion sold Oct 1–15, slowing to the ₩1 trillion range from Oct 16 before picking up again |
| ② Super-week caution | Trimming before results | A Daishin Securities analyst said waiting outweighed both dip-buying and panic-selling |
| ③ AI capex worries | Will big tech's huge spending pay off? | On Oct 23 the Dow fell 1.23%, S&P 500 0.52%, Nasdaq 0.21% |
| ④ Oil | Rising crude adds to inflation and rate worries | Middle East risk and oil volatility cited by BusinessKorea |
Item ① is the outcome; ②–④ are the causes. Samsung and SK Hynix make up a large share of the KOSPI. With their results and US big tech's AI spending plans due the same week, trimming chip exposure beforehand is a rational move for global funds. BusinessKorea framed it as portfolio rebalancing and profit-taking in Korean chips. While foreigners sold ₩700 billion, Korea's pension funds concentrated their buying on SK Hynix.
AI-spending anxiety already surfaced in Meta's results last week, when 26% revenue growth came with negative free cash flow and a 7% share drop. Microsoft, Alphabet and Amazon face the same question this week.
3. Chip-equipment makers fell hardest
| Stock | Change | Close |
|---|---|---|
| Samsung Electronics | −1.16% | ₩213,000 |
| SK Hynix | −0.16% | ₩1,275,000 |
| KB Financial | −3.79% | ₩147,200 |
| Hyundai Motor | −2.54% | ₩288,000 |
| LG Energy Solution | −2.09% | ₩375,000 |
| Jusung Engineering (KOSDAQ) | −6.84% | — |
| Wonik IPS (KOSDAQ) | −6.49% | — |
| EO Technics (KOSDAQ) | −6.19% | — |
Equipment makers' revenue depends on chipmakers' capital spending, so any hint of slower AI investment hits them harder than the chipmakers themselves. On the KOSDAQ, 1,309 stocks fell and 370 rose.
4. The worst one-month drop among major markets
| Index | One-month change (as of Oct 23) |
|---|---|
| KOSPI | −21.6% |
| Hang Seng | −5.8% |
| Nikkei 225 | −5.5% |
| Nasdaq | −4.1% |
| S&P 500 | −1.5% |
The KOSPI plunged 7.57% in a single day on October 15 and fell 14.46% that week. After a steep run-up through September, the pullback has been equally steep; BusinessKorea described pent-up macro anxiety and rally fatigue being released at once.
5. This week's calendar (Korea time)
| Date (KST) | Event | What to watch |
|---|---|---|
| Oct 28 | SK Hynix Q3 results (as reported) | HBM sales, Q4 outlook |
| Oct 29, 3 a.m. | US Fed FOMC decision | Hold or not; December signals |
