Broad Rally: KOSPI +1.75%, KOSDAQ +1.20% — Korea Close & Tomorrow Outlook 26/05/14
Hey, Dongchun here.
Here is how the Korean market closed today.
The one fact that defines today is that retail investors went head-to-head with foreigners and won. Foreigners dumped KRW 2.85 trillion and retail bought KRW 2.83 trillion — a near-perfect one-to-one offset that pushed the KOSPI to a record close. Watch tonight's tepid Nasdaq futures (+0.43%) and whether foreign selling hits a 7th straight day; the rally's durability now rests entirely on domestic buying stamina.

1. Korea Market Close
The KOSPI closed +1.75% at 7,981.41, a fresh record close just 18 points shy of the 8,000 milestone. The KOSDAQ rose +1.20% to 1,191.09, moving in lockstep with the main board.
The single biggest driver was a retail-versus-foreign standoff. Foreign investors net sold KRW 2.85 trillion on the KOSPI — a sixth straight selling session, partly inflated by monthly options expiry liquidation — while retail investors net bought KRW 2.83 trillion, absorbing nearly the entire foreign supply.
Today's move was broad rather than narrow. Strength spread from semiconductors into internet and battery names, and despite being an options expiry day, the VIX held at 17.86 with no volatility shock — domestic demand quietly soaked up the expiry-related supply.
| Index | Close | Change | Volume |
|---|---|---|---|
| KOSPI | 7,981.41 | +1.75% | Options expiry day |
| KOSDAQ | 1,191.09 | +1.20% | Coordinated with KOSPI |
2. Foreign Flow Analysis
Foreign investors net sold KRW 2.85 trillion on the KOSPI, extending their selling streak to six sessions. The flow was partly tied to monthly options expiry liquidation, but the persistence signals foreign conviction has not yet turned despite the record-high index.
Institutions were a small net seller on the KOSPI (-KRW 234 billion) but a net buyer on the KOSDAQ (+KRW 65 billion). Retail investors were the decisive force, net buying KRW 2.83 trillion on the KOSPI — almost a one-to-one offset against the foreign exit.
The combined pattern means tomorrow's session hinges on retail stamina, not foreign return. Overnight US futures are the leading tell to watch tonight: at only +0.43% on the Nasdaq, the external tailwind has cooled sharply from yesterday.
| Investor | KOSPI Net | KOSDAQ Net | Trend |
|---|---|---|---|
| Foreigners | -KRW 2,845 B | -KRW 149 B | 6th straight selling session |
| Institutions | -KRW 234 B | +KRW 65 B | Mixed, small size |
| Retail | +KRW 2,825 B | +KRW 88 B | Absorbed nearly all foreign supply |
3. Sector Breakdown
The dominant theme was a rotation that broadened the rally beyond chips. With US semiconductors strong overnight (SOX +2.57%), money rotated from extended chip names into internet and battery stocks on the Korea board.
The top gaining sectors were internet and semiconductors. Kakao (035720) jumped +6.98% and NAVER (035420) rose +5.71%, far outpacing the index, while Samsung Electronics (005930) gained +4.23% — though SK Hynix (000660) decoupled at -0.30% on profit-taking after its +7.68% surge the prior day.
The laggards were shipbuilding and power equipment. HD Hyunday Heavy Industries fell sharply at -8.46%, with Doosan Enerbility -2.42% and SK Square -1.60% also weak. LG Energy Solution (373220) at +2.79% and Samsung C&T at +3.15% sat on the strong side.
Watch internet and semiconductors tomorrow for follow-through.
| Sector | Direction | Key Stock | Change | Reason |
|---|---|---|---|---|
| Internet | ▲ Strong | Kakao (035720) | +6.98% | Rotation out of extended chips |
| Internet | ▲ Strong | NAVER (035420) | +5.71% | Sector rotation inflow |
| Semiconductors | ▲ Strong | Samsung Elec (005930) | +4.23% | SOX +2.57% spillover |
| Semiconductors | ▬ Flat | SK Hynix (000660) | -0.30% | Profit-taking after +7.68% |
| Batteries | ▲ Strong | LG Energy (373220) | +2.79% | Risk-on broadening |
| Shipbuilding | ▼ Weak | HD Hyundai Heavy | -8.46% | Sharp sector pullback |
4. Stocks on My Radar
| Ticker | Price | Session % | Key Event |
|---|---|---|---|
| BMNR | $21.18 | -2.26% | Crypto risk-off persists; 5.21M ETH reserves intact |
| NVO | $47.08 | +0.17% | Wegovy beat + FY26 guide raise digested |
| ZETA | $16.04 | -1.29% | Profit-taking after Q1 +50% revenue growth |
| ORCL | $189.76 | +1.57% | Oppenheimer PT $210→$235; AI CAPEX tailwind |
| SMR | $11.96 | -0.33% | Citi/GS PT cuts digested; class-action overhang |
| COIN | $201.80 | -2.81% | Q1 EPS miss aftershock; exchange volumes -48% |
| LAES | $2.96 | +0.68% | Quantum-resistant RISC-V chip pipeline intact |
| ASTS | $74.81 | +2.54% | Roth PT $82.50→$108; Golden Dome exposure |
BMNR drifted -2.26% as bitcoin-channel risk-off dominated, even with 5.21 million ETH and $13.4 billion total assets on the balance sheet. NVO held flat at +0.17% as profit-taking and momentum buying balanced out after the Wegovy beat and FY26 guidance upgrade.
ZETA fell -1.29% as profit-taking continued after the Q1 +50% revenue print; the 11-analyst PT consensus of $28.27 is unchanged. ORCL rose +1.57% on Oppenheimer's PT lift to $235 and a clean ride on the AI infrastructure CAPEX theme.
SMR was nearly flat at -0.33% as Citi and Goldman PT cuts were absorbed, with the ENTRA1 class-action overhang still a variable. COIN slid -2.81% on lingering aftershock from its Q1 EPS miss, with global exchange volumes down 48% from October 2025 peaks.
LAES rose +0.68% as post-AGM profit-taking faded with the quantum-resistant chip pipeline intact. ASTS rebounded +2.54% on Roth Capital's PT raise to $108 and Trump's Golden Dome defense initiative, which lists military comms and satellite as direct exposure.
5. Earnings Watch
The Korean earnings calendar is light into next week, with no major large-cap releases today.
| Company | Report Date | EPS Consensus (KRW) | Revenue Consensus | Watch For |
|---|---|---|---|---|
| SK Holdings (034730) | 2026-05-21 | 11,019 | KRW 31.63T | Refining/energy flow-through from SK Innovation Q1 beat |
SK Holdings on May 21 is the next inflection point. The biggest read-through is concentrated in refining and energy — whether SK Innovation's Q1 surprise fully flows through to the group-level result will drive the re-rating debate for Korean refiners.
The Korea takeaway for tomorrow is that with the earnings calendar empty, index direction will be steered by flows and macro rather than fundamentals. That puts the spotlight squarely on the foreign-versus-retail tug-of-war.
6. Options Expiry
Today was Korea's monthly options expiry, with roughly KRW 3 trillion in options expiring. Part of the KRW 2.85 trillion foreign net sell on the KOSPI was tied to expiry-related liquidation.
The volatility impact was contained — retail buying absorbed the foreign and institutional liquidation flow, and the index closed at a record high rather than wobbling. Tomorrow is the first post-expiry session, so expiry-driven supply distortion should clear and the market's pure directional bias should show through.
7. Tomorrow's Korea Open
Nasdaq futures sit at +0.43% and S&P 500 futures at +0.21% — modestly positive but sharply cooled from yesterday's +1.60%. That points to a flat-to-slightly-positive KOSPI open around the 8,000 mark rather than a strong gap up.
There are no major after-hours semiconductor or AI earnings tonight with a direct Korea read-through. Yesterday's after-hours saw Nebius surge +17% on an eightfold revenue jump, Eos Energy beat then fade, and Birkenstock fall -5.5% on an earnings and revenue miss — none of which materially move Samsung Electronics or SK Hynix.
The macro focus is the US 10-year yield at 4.48% after the +6% April PPI shock; a settle above 4.50% would compress high-multiple Korean internet names. VIX at 17.86 signals a calm risk backdrop for now.
| Scenario | Trigger Condition | KOSPI Target |
|---|---|---|
| Bull | Nasdaq futures hold above +0.5%, foreign selling streak breaks, retail net buy stays above +KRW 2T | Breaks 8,000 |
| Neutral | Futures flat, foreign selling continues but retail buying holds | 7,900–8,000 range |
| Bear | Nasdaq futures turn negative, retail buying fades, USD/KRW back above 1,490 | Tests 7,800 support |
The base case for tomorrow is a 7,900–8,000 range as the market tests the milestone with cooled overnight futures and a still-selling foreign bid. Readers without direct KRX access can track this via EWY (iShares MSCI South Korea) or the Samsung Electronics GDR.
Foreigners have sold for six straight sessions and the index still printed a record high. The whole rally now hangs on retail stamina — and that stamina decides whether 8,000 falls.
So — where does this leave us going into tomorrow?
That's the PM breakdown for May 14. Trade safe.
