Key Highlights

  • The Kospi fell 2.2% to 5,880.25 on Thursday, October 29, 2026, while Samsung Electronics dropped 5.4% a day after reporting a record-revenue quarter. A conflicting recap shows a different figure.
  • SK hynix still rose 1.6% the same day, and Taiwan's Taiex fell 1.9%, so the weakness was uneven across Asian chip names. So the day was not a blanket chip selloff.
  • Samsung's shareholder-return plan disappointed some investors, according to a recap, one day after SK hynix's blowout results lifted memory stocks. That explanation comes from one recap and is not a company statement.
  • Another recap puts the Kospi decline at 2.44%, and a claim that Samsung's net profit missed estimates is unverified, so figures are stated with caution.

What Happened in Seoul

The Kospi closed down 2.2% at 5,880.25 on October 29, 2026, with Samsung Electronics down 5.4%. A conflicting recap shows 2.44%, so the decline is stated as about 2.2%. Samsung had reported a record-revenue quarter, yet the shares fell. Other Asian markets were mixed: Nikkei 225 gained 0.2% to 64,073.17, Taiwan's Taiex fell 1.9%, Shanghai fell 0.9% and the Hang Seng was flat. SK hynix rose 1.6% in Korea. For US investors, the iShares MSCI South Korea ETF (NYSEARCA:EWY) is a tradable proxy for Korean equities, but no price move for it was verified, so none is quoted. The day shows how one stock can drag an index.

Why Record Sales Did Not Lift Samsung

Share prices reflect expectations, not results alone. SK hynix had reported operating profit of 83.33 trillion won the day before, which raised the bar for Korean memory makers. A recap said Samsung's shareholder-return plan, covering buybacks and dividends, disappointed some investors, and capital returns matter because they give a direct payout from profits. Because Samsung is a very large part of the Kospi, a 5.4% drop weighs heavily on the index. One recap also says Samsung's net profit missed estimates, but that is unverified here. This article treats the return-plan explanation as a recap's view, not a company statement, and the iShares MSCI South Korea ETF (NYSEARCA:EWY) mix would reflect that concentration.

Risks and What to Watch

A falling Kospi after a strong AI memory print raises the question of whether good news is already priced in. Risks include a hawkish Fed after the October 28 hold at 3.75% to 4.00%, with a December hike priced above 80%, a strong dollar and more volatility in Asian chip stocks. For US-based investors, currency also matters, because Korean won moves affect returns on the iShares MSCI South Korea ETF (NYSEARCA:EWY). Watch the Bank of Japan decision on Friday, the next Samsung update on shareholder returns, and whether the Kospi holds the 5,880.25 level. The index level is a key line. Each of these could weigh on sentiment.

Where Things Stand

The Kospi fell 2.2% because a few very large stocks, led by Samsung Electronics at minus 5.4%, dropped sharply even after record revenue, and a recap tied this to a disappointing shareholder-return plan. SK hynix and Korean funds such as the iShares MSCI South Korea ETF (NYSEARCA:EWY) face the same market backdrop, though no ETF price move was verified. The explanation is a recap's view, not an official statement. Watch the Bank of Japan decision on Friday, further Samsung comment and the follow-through in Seoul.
