On Friday, May 29, 2026, Korean equities delivered a sharply divided session. Shaking off the prior day's shock from the U.S. strike on Iran, hopes for a U.S.-Iran ceasefire drove the KOSPI up +3.55% to a record closing high, while the KOSDAQ slid -2.68%, marking its third straight losing session.

📈 KOSPI Analysis
The KOSPI closed at 8,476.15, up 290.86 points (+3.55%) from the previous session (8,185.29), setting a fresh record closing high. After the U.S. strike on Iran had pushed the index down to the 7,800 zone intraday the day before, the market staged a V-shaped rebound within a single day as ceasefire expectations took hold.
From the intraday low of 8,273.74, the index built momentum into the close, finishing at its session high of 8,476.15. LG Group and electronics large-caps led the charge — LG Electronics, LG CNS, and Samsung Electro-Mechanics (pref.) all locked limit-up, while LG Innotek and Hyundai AutoEver surged. Samsung Electronics' market capitalization topped KRW 2,000 trillion. Electronics products, IT services, and electronic equipment sectors spearheaded the advance.
📉 KOSDAQ Analysis
The KOSDAQ closed at 1,074.80, down 29.56 points (-2.68%) from the prior session (1,104.36), extending its losing streak to three sessions. The session's high (1,112.15) was the opening print; the index flipped negative right at the open and fell to a low of 1,058.13, pressured by selling all day.
With buying concentrated in large-cap KOSPI names, small- and mid-caps were left behind — a textbook case of flow polarization. Even so, theme differentiation persisted: Objet, Flitto, Nuriplan, and TS Investment locked limit-up, while AI and robotics names such as Robostar, X-Lab, Namu Tech, and Sena Technologies posted gains.
🔥 Key Themes & Sectors
📌 LG Group & Electronics (Up)
LG Electronics, LG CNS, and Samsung Electro-Mechanics (pref.) all hit limit-up, while LG Innotek (+KRW 324,000), LG Corp, and TIGER LG Group Plus rallied in tandem. Strength in Electronics Products (+29.19%) and Electronic Equipment (+14.27%) propelled the KOSPI to its record high.
📌 Semiconductor Super-Cycle (Up)
With Samsung Electronics' market cap crossing KRW 2,000 trillion, the "super-cycle vs. super-bubble" debate intensified. Chatter even turned to a possible KOSPI 10,000, cementing semiconductors as the market's clear leadership.
📌 AI & Robotics (Up)
Despite the KOSDAQ's weakness, AI and robotics themes — Robostar, X-Lab, Namu Tech, Objet (limit-up), and Sena Technologies — showed selective strength.
📌 Natural Gas Inverse ETNs (Down)
Inverse 2X natural gas futures ETNs from Meritz, Hana, Samsung, Shinhan, and KB dominated the KOSPI's biggest decliners, reflecting heavy exposure to natural gas price volatility.
💰 Foreign & Institutional Flow
Investor-by-investor trading data (foreign, institutional, retail) was not compiled for the session, limiting quantitative interpretation. However, given the pronounced strength in large-cap KOSPI names (LG Group, electronics), the KOSDAQ's exclusion, and the won's appreciation toward the 1,500 level, it is highly likely that foreign and institutional buying was concentrated in top KOSPI market-cap names.
🌍 Global Factors
U.S. equities rose across the board the prior session, led by technology.
| Index | Close | Change |
|---|---|---|
| S&P 500 | 7,563.63 | +0.58% |
| NASDAQ | 26,917.47 | +0.91% |
| Dow Jones | 50,668.97 | +0.05% |
Above all, the U.S. strike on Iran that had triggered the previous day's KOSPI plunge flipped into "ceasefire hopes," temporarily easing geopolitical risk — the core driver behind today's V-shaped rebound. Bitcoin held in the USD 73,500 range. Meanwhile, Bank of Korea Governor Shin Hyun-song's first Monetary Policy Board meeting was read as a "hawkish hold," raising the prospect of a rate-hike signal within the year as a potential headwind.

- Key news: "It all comes back to semiconductors!" — conditions for KOSPI 10,000 amid the super-cycle vs. super-bubble debate; BOK Governor Shin Hyun-song's first MPB meeting read as a hawkish hold, seen as a possible trigger for a rate hike within the year.
🔮 Next Session Outlook
As today is Friday, the next trading day is Monday, June 1. If ceasefire hopes and the momentum in semiconductor and electronics leaders hold, the KOSPI may attempt to settle above the 8,500 level. However, profit-taking and overheating concerns following a single-day +3.55% surge remain. Whether the KOSDAQ — down for three straight sessions — can rebound, and whether the flow concentration into the KOSPI eases, will be the key variables shaping the next session's tone.
