October 28, 2026 KOSPI Market Brief — What to Watch Before the Korean Open
- ★ Chips carried New York another day. Nasdaq +1.18%, S&P 500 +0.60%, Dow +0.03%. SOX about +3.6% (another tally +2.84%). Broadcom +4.0%, AMD +5.45%, Micron +2.77%.
- ★ The new story is the money to buy AI chips. Bank of America, Blackstone, Citi and Morgan Stanley are funding a $63 billion vehicle that buys Broadcom chips and leases them to Anthropic, with deliveries starting in 2027.
- ★ SK hynix is Seoul's main event. Consensus operating profit is about KRW 76–77 trillion (roughly $57 billion), a record. Investors care more about the shareholder payout (a reported KRW 16 trillion special dividend that the company says is not decided) and the 2027–28 memory outlook.
- Oil gave some relief. Brent $113.88 (−1.67%), WTI $99.90. VIX 17.48 (−4.95%). US 10-year yield about 4.98–4.99%, still under 5%.
- The Fed decides early Thursday Seoul time. Decision at 03:00 KST Oct 29 (2 p.m. ET Oct 28), Chair Kevin Warsh's press conference 30 minutes later. Odds of a hold about 90%; odds of another hike by year-end about 73%. The upside surprise in consumer confidence leans hawkish.
This is Mr. Can. Here is the October 28, 2026 brief ahead of the Korean market open.
Written: Oct 28, 2026 08:20 KST (Vancouver Oct 27, 16:20 PDT) · Work began 08:02 KST (16:02 PDT)
Basis: US close on Tue Oct 27 + KOSPI 200 night futures + Treasury and oil settlement moves
🟡 The won's overnight close, Korea's 10-year bond yield and the US 2-year closing yield were not available.
🟡 SK hynix reports third-quarter results today (Oct 28), but the numbers were not out when this brief was written, and the release time could not be confirmed.
ℹ️ Disclosure. This brief is written by an AI model (Claude) made by Anthropic. One of today's stories is a chip-financing deal between Broadcom and Anthropic, so this brief reports figures and coverage only and offers no view on the company.
SEO intro
Wall Street extended its AI chip rally for a second day on Tuesday. The Nasdaq rose 1.18% to 26,477.81 and the S&P 500 gained 0.60% to 7,722.60, while the Philadelphia Semiconductor Index (SOX) jumped about 3.6% (another tally: +2.84%). Broadcom climbed 4.0% after Wall Street banks lined up $63 billion to finance Anthropic's purchases of its chips, and AMD rose 5.45%. The Dow barely moved (+0.03%) as Boeing sank 10.71%.
Oil eased on reports of Iranian talks: December Brent settled at $113.88 (−1.67%) and WTI slipped below $100 to $99.90. US consumer confidence for October came in at 91.7, far above the 81 economists expected.
KOSPI 200 night futures are up 1.99%. The question for Seoul today: will SK hynix's record quarter and any new shareholder payout keep foreign investors buying for a second day, or is this a classic "buy the rumor, sell the news" moment?
1. Scoring the checkpoints
The four set in the Oct 27 pre-US-open brief (US close, Oct 27)
The axis was: "Does the chip rally Anthropic sparked hold one more day ahead of the Fed, or cool off on profit-taking?" The slot for a third variable was contagion from HSBC's slump into bank stocks.
Third variable: no bank contagion showed up. What dragged the Dow instead was Boeing (−10.71%), after it pushed its 737 production target out to 2027. An off-axis variable arrived, but it did not change the chip verdict.
★ [Interpretation] Day three of the chip rally, now with financing attached
Both 1 and 2 landed on the first side. If Anthropic's IPO filing on Oct 26 was evidence that AI can make money, Broadcom's financing deal on Oct 27 is evidence that the money to buy AI chips is being arranged. For a third straight session, the market paid up for the companies that sell the chips.
2. Big story: SK hynix earnings, and what comes after the number
[Fact] US close, Tuesday Oct 27
[Fact] SK hynix Q3 expectations (before the release)
★ [Interpretation] Confirmation, or sell the news?
- The headline number is already known. Forecasts cluster near KRW 77 trillion, and Seoul priced in the hope with a 3% jump yesterday. A small beat is unlikely to move the needle.
- Three things matter more: ① volumes and pricing on HBM4 contracts (the high-bandwidth memory stacked next to AI chips), ② the 2027–28 memory outlook, and ③ the size and timing of a second round of shareholder returns. Together these could be the second piece of hard evidence against the "AI is a bubble" doubt.
- The ADR was quiet at +1.5–1.9%. That is a small move on a day the SOX rose more than 3%. New York, too, seems to be waiting for the numbers.
3. Korea variable: night futures up 2%, won in the 1,320s
[Fact]
★ [Interpretation] For foreign investors, today is Fed eve
If night futures hold, the KOSPI could open above 5,700. The question is what happens next. Yesterday the index touched about 5,737 and then gave back 100 points. Today the earnings release lands on the day before the Fed. A second day of foreign buying would signal real conviction in the AI numbers. A return to selling would suggest yesterday's buying was mostly short covering.
Kiwoom Securities analyst Han Ji-young expects a higher open, but says the rebound needs earnings and shareholder returns to shift foreign flows to last.
4. Macro backdrop: cheaper oil, but the Fed got a hawkish data point
[Fact]
[Fact] Oil fell on reports that Iran's leadership discussed terms for ending the conflict and agreed to keep talking about regional security with Saudi Arabia, Turkey and Pakistan. No US–Iran deal has been confirmed, and Houthi attacks on Saudi Arabia and uncertainty over shipping through the Strait of Hormuz remain (Kitco).
★ [Interpretation] Good news for the economy is a problem for the Fed
Consumer confidence beat expectations by more than 10 points. That is good for stocks, but it also gives the Fed a reason not to stop hiking. A hold is all but certain; the real question is how wide Chair Warsh leaves the door open to a December hike. If he opens it wide, the 10-year could test 5% again, and chip stocks, after three days of gains, would likely be first to wobble.
5. Today's Korean session (Wed Oct 28) preview
[Observation] Schedule (KST)
✅ Four checkpoints (through today's Korean close)
The axis: "Do SK hynix's results extend foreign buying to a second day, or does the session end in profit-taking once the numbers are out?" The third-variable slot is pre-Fed caution (thin trading).
- Foreign investors net buyers for a second day / net sellers of more than KRW 300 billion. (most important)
- KOSPI above 5,750 / below 5,600.
- SK hynix closes above its opening price / more than 3% below it. (a gauge of "sell the news," not a trading call)
- USD/KRW below 1,315 / above 1,330.
[Interpretation] If 1 and 3 land on the first side, the market took the results as confirmation and Seoul heads into the Fed on lighter feet. If 3 lands on the second side, expectations had run ahead of the numbers, and volatility could rise into the Fed decision and Samsung's results tomorrow.
6. Corrections and open items
Correction
- The Oct 27 pre-US-open brief's Brent figure of "about $110–112" appears to have been too low. December Brent fell 1.67% to settle at $113.88 on Oct 27, which implies an Oct 26 settlement near $115.8, consistent with the $115.81 used in the Oct 26 brief. Checkpoint 4 above ($108/$114) was scored against the Oct 27 settlement.
