A WSJ report that OpenAI missed internal revenue and user targets ended an 18-day chip rally | Nasdaq -0.90%, S&P -0.49% — Korea Open Preview 26/04/29
Hey, Dongchun here.
The single most important fact today is that one OpenAI revenue-miss headline broke an 18-day chip-stock rally — Oracle -4.05%, Broadcom -4%, AMD -3% — and that contagion now lands on Korean memory names. The reason it matters is that AI CAPEX visibility, the foundation of HBM demand for SK Hynix and Samsung Electronics, is suddenly under question. Watch two things: foreigners' first-five-minute net flow in Samsung Electronics (005930) at the 9 a.m.
KST open, and tonight's Microsoft/Alphabet/Meta CAPEX guidance — together they decide whether OpenAI is noise or signal.

1. US Session Recap
The S&P 500 closed at 7,138.80 (-0.49%), the Nasdaq at 24,663.80 (-0.90%), the Dow at 49,141.93 (-0.05%) and the Russell 2000 at 2,756.05 (-1.15%). The split tape — narrow Dow weakness, deep small-cap selling, and a savaged Philly Semiconductor Index (-3.58%) — shows a single-sector rout rather than broad risk-off.
The driver was a Wall Street Journal report stating that OpenAI missed internal revenue and user-growth targets, with CFO Sarah Friar reportedly worried the company may not cover future computing-contract obligations. Oracle, which holds a $300B five-year compute deal with OpenAI, fell 4.05%; Broadcom around -4%, AMD around -3%, and Nvidia around -1.5%.
Breadth was narrow but not panicked. VIX fell 1.05% to 17.83 even as Russell underperformed Nasdaq; the move looked like profit-taking after an 18-day chip rally rather than capitulation. Energy stocks bucked the tape as WTI crude rose 3.24% to $99.49 on Hormuz tensions.
For Korea, the direct read-through is on memory: SK Hynix (000660) and Samsung Electronics (005930) are exposed to AI-CAPEX sentiment shifts via HBM demand. Hyundai Motor (005380) and auto-parts complex remain insulated by GM/NXP positive earnings.
| Index | Close | Change |
|---|---|---|
| S&P 500 | 7,138.80 | -0.49% |
| Nasdaq | 24,663.80 | -0.90% |
| Dow Jones | 49,141.93 | -0.05% |
| Russell 2000 | 2,756.05 | -1.15% |
2. Korea Market Snapshot
KOSPI closed at 6,615.03 (+2.15%, +139.40 points) and KOSDAQ at 1,226.18 (+1.86%, +22.34 points), with both indices riding a broad mega-cap rotation. The level keeps KOSPI within the 6,600 record-high zone first reached last week.
Foreign and institutional flows favored non-semiconductor mega caps. Hyundai Motor +5.92% led with Q1 record-high revenue momentum, NAVER +2.09% on bargain hunting, and LG Energy Solution +1.72% on a battery rebound. Samsung Electronics diverged at -1.11% on AMD overnight spillover.
The combined flow pattern implies the next session hinges on whether foreigners stay constructive after the US OpenAI-driven chip selloff. With overnight Nasdaq futures at -0.79% and FOMC tonight, the gap-down risk is concentrated in semis — autos and internet should hold firmer.
| Index | Prev Close | Change | Key Level |
|---|---|---|---|
| KOSPI | 6,615.03 | +2.15% | 6,600 record zone |
| KOSDAQ | 1,226.18 | +1.86% | 1,220 resistance hold |
| Investor | KOSPI Net | KOSDAQ Net | Trend |
|---|---|---|---|
| Foreigners | Net buy bias | Mixed | Rotating into non-semis |
| Institutions | Net buy bias | Net buy | Mega-cap accumulation |
| Retail | Mixed | Net buy | Absorbing dips |
3. Korea Sector Breakdown
The dominant theme overnight was a single-sector chip rout sparked by the OpenAI revenue-miss WSJ report, set against a Korea session that had already locked in mega-cap rotation gains. Watch chip-vs-non-chip divergence today.
Top Korean gainers: Autos with Hyundai Motor (005380) +5.92% on tariff easing and Q1 record revenue. Internet/AI with NAVER (035420) +2.09% on bargain hunting. Batteries with LG Energy Solution (373220) +1.72% extending a rebound.
Top Korean laggards-to-watch on the open: Memory semis with Samsung Electronics (005930) at -1.11% facing further pressure from SOX -3.58%. AI infrastructure proxies tied to US hyperscaler CAPEX could see profit-taking ahead of MSFT/GOOGL/META tonight.
| Sector | US Session | Korea Stock | Korea Move | Watch |
|---|---|---|---|---|
| Semiconductors | ▼ SOX -3.58% | Samsung (005930), SK Hynix (000660) | -1.11% / +0.62% | KODEX Semiconductor |
| Autos | ▲ GM positive | Hyundai (005380) | +5.92% | NXP guidance read-through |
| Internet | ▼ Mild | NAVER (035420) | +2.09% | GOOGL/META tonight |
| Batteries | ▲ Mild | LG Energy (373220) | +1.72% | TIGER 2차전지 |
| Energy | ▲ WTI +3.24% | S-Oil, refiners | Mixed | Hormuz tension |
4. Stocks on My Radar
| Ticker | Price | Session % | Key Event |
|---|---|---|---|
| BMNR | $21.48 | -0.32% | NYSE uplisting + $4B buyback expansion announced; tracked BTC weakness near $80K |
| NVO | $41.17 | -0.07% | DKK 15B buyback ongoing; AI drug-development partnership announced; 2026 sales guide-down overhang |
| ZETA | $17.77 | -1.77% | Q1 prints April 30; consensus EPS $0.13, revenue $370M (+39.9% YoY) |
| ORCL | $165.96 | -4.05% | OpenAI $300B compute deal scrutiny; off intraday low of -7.7% premarket |
| SMR | $11.82 | -6.56% | Citi cut PT to $9 (Sell); ENTRA1 class actions; Fluor exited $2.43B stake |
| COIN | $194.10 | -1.31% | BTC failed at $80K resistance; Q1 results due May 7 |
| LAES | $2.77 | -2.81% | Q1 revenue $4.1M (+200% YoY) but caught in chip-sector selling |
| ASTS | $71.88 | -6.89% | BlueBird-7 placed in lower-than-planned orbit by Blue Origin's New Glenn-3; BofA keeps thesis intact |
BMNR's NYSE uplisting and $4B buyback expansion are clean fundamental catalysts, but the price slipped 0.32% as Bitcoin softness around $80K dragged crypto-treasury proxies. ORCL's 4.05% drop directly reflects the WSJ OpenAI revenue-miss report given the $300B compute-supply contract; Wedbush's Dan Ives reiterated Outperform arguing the market is misreading capex as risk. SMR cratered 6.56% as Citi slashed its price target to $9 with a Sell rating, compounded by ENTRA1 class-action litigation and Fluor's full $2.43B exit.
ASTS lost 6.89% after BlueBird-7 was placed in a lower-than-planned orbit by New Glenn-3, though BofA kept the year-end 45-satellite target intact under insurance recovery.
5. FOMC Watch
The April FOMC statement drops at 3 a.m. KST on April 30 (2 p.m. ET on April 29), with Powell's press conference at 3:30 a.m.
KST. CME FedWatch shows a 100% probability of a hold at 3.50–3.75%, marking the third consecutive pause and the most certain consensus of the year.
Two variables decide the tone. First, March CPI accelerated to +3.3% YoY from +2.4% in February, and oil is climbing again — if Powell sharpens the inflation-risk language, markets will read it hawkish. Second, this is Powell's final press conference before his term expires May 15, and the handoff tone toward presumed successor Kevin Warsh is itself a market signal.
The KRW and Korea bond reaction map is straightforward. Dovish tone: USD/KRW slips toward 1,470, 10Y KTB attempts to break 4.30%, and KOSPI can recover the overnight gap. Hawkish tone: USD/KRW reclaims 1,475, 10Y pushes toward 4.40%, and chip names face additional supply.
6. Earnings Watch
This is the peak week of mega-cap earnings. Visa and NXP reported after Tuesday's close; Microsoft, Alphabet and Meta all report after Wednesday's close (5 a.m. KST Thursday).
| Company | EPS Est | EPS Actual | Rev Est | Rev Actual | Result | After-Hours |
|---|---|---|---|---|---|---|
| Visa | $3.09 | $3.31 | $10.7B | $11.2B | EPS and revenue beat | Higher |
| NXP | $2.97 | $3.05 | $3.16B | $3.18B | Beat; Q2 guide raised to $3.45B | +11.4% |
Visa confirmed resilient global consumer spending with payment volume +9% and cross-border +12%. NXP validated the auto-semiconductor recovery with an after-hours surge of +11.4% — directly supportive for Hyundai Mobis and the Korean auto-parts complex.
| Company | Time (ET) | Consensus EPS | Watch For |
|---|---|---|---|
| Microsoft | After close | $3.51 | Azure growth rate, AI CAPEX guidance |
| Alphabet | After close | $2.83 | Google Cloud revenue, AI-search monetization |
| Meta | After close | $6.67 | AI CAPEX scale, advertising revenue trend |
Korea read-through is sharp. HBM names (SK Hynix 000660, Samsung Electronics 005930) live or die on the AI-CAPEX guidance from MSFT Azure and Meta. Internet (NAVER 035420, Kakao 035720) reads Alphabet search and Meta ad revenue as a confidence proxy.
AI-infrastructure proxies depend on whether the Big Three's CAPEX tone validates or dismisses the OpenAI revenue-miss report.
7. Today's Trade Setup
KOSPI is set to open with a -0.4 to -0.8% gap reflecting Nasdaq futures -0.79% and the SOX -3.58% chip rout. The primary driver is single-sector contagion risk in memory and AI-infrastructure proxies, partially offset by NXP's after-hours +11.4% on Q1 beat that supports auto-parts read-throughs.
The single most important indicator to watch is foreigners' net buy/sell in Samsung Electronics (005930) during the 9:00–9:05 a.m. KST opening five minutes. Samsung flow leads KOSPI direction because foreigners use it as the primary liquidity proxy for Korea-wide AI-memory exposure; a clean net-buy of +50B KRW in the first five minutes signals US chip selling was profit-taking, while accelerating sells signal contagion.
Top two sectors to focus on today: Memory semiconductors — Samsung Electronics (005930) and SK Hynix (000660) face direct SOX -3.58% spillover and need MSFT/GOOGL/META CAPEX confirmation tonight. Autos — Hyundai Motor (005380) and Kia (000270) get a tailwind from GM solid earnings and NXP's auto-semi guide-up.
| Scenario | Trigger Condition | KOSPI Target |
|---|---|---|
| Bull | Powell dovish tone + MSFT/GOOGL/META capex up + foreign Samsung net buy > +100B KRW | 6,650 retest |
| Neutral | Hold + neutral tone, mixed mega-cap guidance | 6,520–6,615 |
| Bear | Powell hawkish surprise + capex disappoint + foreign Samsung sell > -150B KRW | 6,450 support test |
Base case: KOSPI trades inside 6,520–6,615 ahead of the 3 a.m. KST FOMC and 5 a.m. KST tech-trio earnings, with autos firm and memory under pressure.
International readers without KRX access can express the Korea view via EWY (iShares MSCI Korea ETF) or Samsung Electronics GDR.
One headline broke the chip rally, but the verdict comes tonight when Microsoft, Alphabet and Meta hand in their CAPEX numbers. Until those land, no direction is final.
That's the AM breakdown for April 29. Trade safe.
