KOSPI Up, KOSDAQ Lags: KOSPI +1.43%, KOSDAQ -0.91% — Korea Close & Tomorrow Outlook 26/05/07
Hey, Dongchun here.
Here is how the Korean market closed today.
The only thing that matters today is that foreigners hit KOSPI with a single-session record -7.15 trillion KRW sell program and Korea still printed a fresh all-time high. This matters because retail (+5.99T) and institutions (+1.10T) absorbed the entire wave — a regime shift from the foreign-dominated rally of the last two sessions to a domestically-balanced bid that hasn't been seen at this scale in years. Watch tomorrow's first 30 minutes for whether foreign flow stabilizes, and watch the SMR (4 PM ET) and Coinbase (after close) earnings tonight for follow-through into Korea memory and crypto-adjacent names.

1. Korea Market Close
KOSPI closed at 7,490.05, up +105.49 points or +1.43%, marking another fresh all-time high after briefly touching the 7,500 level intraday before pulling back. KOSDAQ diverged sharply, closing at 1,199.18 (-0.91%, -10.99 points), as profit-taking hit biotech leaders Alteogen, HLB and Samchundang Pharm.
The single biggest driver was a flow regime shift. Foreigners reversed yesterday's +3.1T net buy with a single-session record -7.15 trillion KRW sell — but retail (+5.99T) and institutions (+1.10T) combined for roughly +7T of absorption, fully offsetting the foreign exit and pushing the index to a new high.
Breadth was narrow at the top — the rally concentrated in semiconductors (Samsung Electronics +2.07%, SK Hynix +3.31%) and autos (Hyundai Motor +4.00%) — while internet (Kakao -2.27%) and biotech were laggards. VIX held at 17.55 (+0.92%), still well within risk-on territory.
| Index | Close | Change | Volume |
|---|---|---|---|
| KOSPI | 7,490.05 | +1.43% | Record absorption by domestic flow |
| KOSDAQ | 1,199.18 | -0.91% | Biotech profit-taking weighed |
2. Foreign Flow Analysis
Foreigners dumped a single-session record -7,154 billion KRW on KOSPI, concentrating in profit-taking after yesterday's +3.1T historic buy. The reversal scale — roughly 2.3x yesterday's buy — is the largest single-day foreign sell print of 2026 to date and signals locking-in of the +14.41% Samsung / +10.64% SK Hynix gains from May 6.
Institutions came in with +1,098 billion KRW net buy on KOSPI, while retail printed an enormous +5,991 billion KRW — domestic buyers fully absorbed the foreign exit and then some. The pattern looks textbook for a structural-rerating phase where retail conviction meets institutional re-balancing on the back of a major US-driven leg.
The combined flow pattern implies that tomorrow's session hinges on whether foreigners stop selling or extend the program. Tonight's US session — particularly Nasdaq futures direction and SMR/COIN earnings reactions — is the leading indicator to watch for whether memory mega-caps catch a fresh bid at the open.
| Investor | KOSPI Net | KOSDAQ Net | Trend |
|---|---|---|---|
| Foreigners | -7,154 B KRW | Net sell | Single-session record sell |
| Institutions | +1,098 B KRW | Mixed | Defensive accumulation |
| Retail | +5,991 B KRW | Net buy | Aggressive dip-bid into record |
3. Sector Breakdown
The dominant theme is a flow-regime shift inside a continuing US-led semiconductor rally. AMD's +57% YoY data-center beat from May 5 still feeds through into Korean memory, but the Samsung +2.07% / SK Hynix +3.31% prints today are sharply slower than yesterday's +14.41% / +10.64% — a clear sign of momentum normalization rather than acceleration.
Top gaining Korean sectors included autos with Hyundai Motor (005380) +4.00% on continued foreign-rotation flow, semiconductors with Samsung Electronics (005930) +2.07% and SK Hynix (000660) +3.31% on SOX +4.48% follow-through, and shipbuilders on HD Korea Shipbuilding's (009540) Q1 OP +57.8% beat lifting Hanwha Ocean and Samsung Heavy by sympathy.
Top lagging sectors were internet platforms with Kakao (035720) -2.27% post-earnings (revenue miss despite +66% OP beat) dragging NAVER (035420) -0.24%, plus biotech leaders weighing on KOSDAQ -0.91% as Alteogen and HLB saw profit-taking.
| Sector | Direction | Key Stock | Change | Reason |
|---|---|---|---|---|
| Autos | ▲ Strong | Hyundai (005380) | +4.00% | Foreign rotation, EU export thesis |
| Semiconductors | ▲ Moderate | Samsung (005930) | +2.07% | SOX +4.48% follow-through, momentum normalizing |
| Shipbuilders | ▲ Earnings | HD KSOE (009540) | OP +57.8% beat | Eco-ship mix expansion |
| Internet | ▼ Weak | Kakao (035720) | -2.27% | Revenue miss despite OP beat |
| Biotech (KQ) | ▼ Weak | Alteogen / HLB | -1.93% / -3.57% | Profit-taking |

LAES +14.09% climbed on its 5/7 AGM and the Quantum Vertical Stack ecosystem rollout backed by a $200M SEALQuantum Fund and a $525M+ cash position.
5. Earnings Watch
Earnings tonight matter because today's Korea cluster of five large-cap beats sets a very high bar — and SMR plus Coinbase report after the US close, both with sub-$1 EPS consensus and both directly relevant to high-vol Korean exposure baskets.
| Company | OP Est | OP Actual | Rev Est | Rev Actual | Result | Reaction |
|---|---|---|---|---|---|---|
| Celltrion | n/a (EPS 1,322) | 321.9B (+115.5% YoY) | 1.23T | 1.145T | OP surprise | Range-bound |
| Kakao | n/a (EPS 357.65) | 211.4B (+66% YoY) | 2.01T | 1.9421T | OP beat / rev miss | -2.27% |
| HD KSOE | n/a (EPS 10,619) | 1.356T (+57.8% YoY) | 7.96T | 8.1409T | Double beat | Strong |
| HD Hyundai Heavy | n/a (EPS 7,103) | 905.4B | 5.59T | 5.9163T | Beat | Strong |
| LG Electronics | n/a | 1.6736T (+32.9% YoY) | n/a | 23.7330T | Consensus +291.7B beat | Strong |
| LG Energy Solution | n/a | -207.8B (loss-swing) | n/a | 6.555T | Loss swing | +0.21% |
The biggest beat was Celltrion's +115.5% OP growth and HD KSOE's +57.8% on eco-ship mix expansion — both reaffirm structural cycle strength in biopharma and shipbuilding. The biggest miss was LG Energy Solution's swing to a -207.8 billion KRW operating loss vs +374.7B prior-year, though the stock held flat at +0.21% as consensus had already discounted the loss.
| Company | Time (ET) | Consensus EPS | Watch For |
|---|---|---|---|
| NuScale Power (SMR) | 4:00 PM | -$0.11 | Commercial module shipment visibility, AI data-center power demand |
| Coinbase (COIN) | After close | $0.36 | Q1 global volume -48% backdrop, subscription/services resilience |
Korea read-through for tomorrow's open: HD KSOE's +57.8% OP beat directly supports Hanwha Ocean and Samsung Heavy by sympathy, Celltrion's record print supports Samsung Biologics, and the Kakao revenue miss caps near-term internet enthusiasm and pressures NAVER. Memory mega-caps remain dominated by tonight's US futures direction rather than Korean earnings.
6. Tomorrow's Korea Open
US overnight futures sit at S&P +0.18%, Nasdaq +0.17%, Dow +0.26% — a meaningful step-down from yesterday's +1.18% to +1.97% setup. The implication for KOSPI Friday is a flat-to-mild gap-up open rather than another momentum continuation.
The most directly impactful after-hours events are SMR's 4 PM ET Q1 print (consensus EPS -$0.11, focus on commercial module shipment visibility) and Coinbase's after-close release (consensus EPS $0.36, revenue ~$1.31–1.51B against a Q1 global volume -48% backdrop). Neither is a memory-direct catalyst for Samsung Electronics or SK Hynix, but a strong SMR print could lift Doosan Enerbility (034020) by sympathy.
Major macro tonight includes US initial jobless claims (forecast 205K vs prior 189K), continuing claims (1.8M), construction spending (+0.3% forecast), and NY Fed President Williams speaking at 3:30 PM ET. VIX at 17.55 (+0.92%) remains in risk-on territory, while the 10Y at 4.36% (-1.36%) supports continued risk-asset bid.
| Scenario | Trigger Condition | KOSPI Target |
|---|---|---|
| Bull | Nasdaq futures hold +0.17%+, foreign selling normalizes, SMR/COIN earnings beat | 7,500 retest |
| Neutral | Flat gap-up, foreign net sell decelerates, mixed earnings | 7,400–7,500 range |
| Bear | Foreign net sell exceeds another -3T, US earnings miss, VIX above 19 | 7,300 support test |
Base case is a flat gap-up followed by a wait-and-see session as Korea digests whether yesterday's foreign -7.15T print was a one-day profit-taking event or a multi-session trend. International readers without direct KRX access can track iShares MSCI South Korea ETF (EWY) or the Samsung Electronics GDR for clean exposure.
Foreigners pulled 7 trillion in a single tape and Korean retail bought 6 trillion of it without flinching — that is the trade of the session and arguably the trade of the cycle. The next test is whether this newly domestic bid holds up when the foreign tape stops being a one-day event.
So — where does this leave us going into tomorrow?
That's the PM breakdown for May 07. Trade safe.
