[2026-07-30] KOSPI & KOSDAQ Market Close | Korea Extends Losses for a 4th Day on Chip Leverage Unwind

📊 Today's Market at a Glance

Despite Samsung Electronics reporting record second-quarter earnings, a fresh wave of AI-bubble fears and a global semiconductor correction dragged both the KOSPI and KOSDAQ lower for a fourth straight session. The KOSPI briefly climbed to 5,976 in an attempt to reclaim the 6,000 mark before reversing to close -1.23%, while the KOSDAQ deepened its losses to -2.70%.

Index	Open	High	Low	Close	Change	Volume
KOSPI	5,681.77	5,976.82	5,547.41	5,593.56	-1.23%	37,517.1만
KOSDAQ	654.72	677.19	642.95	644.78	-2.70%	45,260.2만

The USD/KRW exchange rate held at an elevated 1,453.16, keeping pressure on foreign inflows. In point terms, the KOSPI fell 69.68 points while the KOSDAQ dropped 17.90 points.

📈 KOSPI Analysis

The KOSPI closed at 5,593.56, down 1.23% (69.68p). The index opened firm at 5,681.77 and rallied intraday to as high as 5,976.82, testing a recovery of the 6,000 level. However, a 150,000-won plunge in Samsung Electro-Mechanics (closing at 879,000 won) and a simultaneous collapse in SK Hynix single-stock leverage ETNs pushed the index down to a session low of 5,547.41 before it settled lower.

Coming on the heels of a 18%-plus slide over the previous three sessions, the day was marked by extreme volatility — a 429-point swing between the intraday high (5,976) and low (5,547). Even Samsung Electronics' record second-quarter results could not offset heavy selling from retail investors and mounting fears of a global chip correction. Shipbuilding, utilities and defense sectors showed strength, but not enough to counter the weakness in large-cap semiconductor names.

📉 KOSDAQ Analysis

The KOSDAQ ended at 644.78, down 2.70% (17.90p), extending its losing streak to a fourth consecutive session. After opening lower at 654.72, it rebounded to 677.19 intraday but renewed selling pressure in the afternoon left it near the session's lows around 644.

With losses more than double those of the KOSPI (-1.23%), the sell-off in leveraged positions and risk-off sentiment appeared concentrated in small- and mid-cap growth names. That said, robotics and AI stocks such as CMES Robotics and Konan Technology, along with catalyst-driven names like KM Pharmaceutical and YAS, surged — several hitting the daily limit-up — signaling rotational buying even within a falling market.

🔥 Key Themes & Sectors

1. Shipbuilding & Defense (Up)

The shipbuilding sector rose +5.00% and aerospace & defense gained +3.90%. The Kiwoom Leverage Shipbuilding TOP10 ETN ranked among the day's top gainers, with defense and shipbuilding themes serving as defensive plays amid the broader decline.

2. Semiconductor Leverage Unwind (Down)

Samsung Electro-Mechanics tumbled 150,000 won, while SK Hynix single-stock leverage ETNs (SOL, ACE, KODEX, RISE and others) dominated the list of biggest decliners. The global chip correction combined with the unwinding of leveraged products was the key driver behind the day's losses.

3. Robotics & AI (Up)

On the KOSDAQ, CMES Robotics hit the limit-up and Konan Technology jumped +2,300 won. Even amid the sharp index decline, short-term flows rotated into individual robotics and AI growth stocks.

4. Utilities & Shipping (Middle East Risk) (Up)

Multi-utilities posted the day's best sector gain at +6.09%. Amid Middle East tensions and oil-price concerns, defensive and inflation-hedge sectors such as shipping, energy and utilities showed relative strength.

5. Construction (Stock-Specific Catalysts) (Up)

Kumho Engineering & Construction and its preferred shares hit the limit-up, while Namhwa Construction surged. Construction names with individual catalysts — earnings or new orders — attracted concentrated short-term buying within the down market.

💰 Foreign & Institutional Flow

Detailed investor-by-investor flow data (net buying amounts for foreign and institutional investors) was not tabulated for the session. According to news reports, however, foreign investors returned as buyers intraday and led the market's rebound, only for the gains to be surrendered under heavy selling from retail investors, leaving the market lower.

Even with foreign investors back on the bid, retail selling and leverage-unwinding pressure prevailed — a tug-of-war session in which no side established clear control of the flow. With USD/KRW holding at an elevated 1,453, the sustainability of foreign net buying remains constrained.

🌍 Global Factors

Overnight, U.S. equities fell sharply across all three major indices on renewed AI-bubble fears and geopolitical tensions stemming from Iran.

Index	Close	Change
Dow Jones	51,594.14	-2.19%
NASDAQ	24,442.94	-1.74%
S&P 500	7,316.15	-1.52%

The FOMC held its benchmark rate at 3.75%, easing worries over further rate hikes, but the semiconductor correction and risk-off sentiment spilled over into Korean equities. Daishin Securities offered a rebound scenario for the KOSPI of 5,700 → 8,200 → 9,300, arguing that "the plunge will stop once leverage liquidation wraps up in early August."

🏆 Notable Stocks

Stock	Change	Reason
Samsung Electro-Mechanics	-14.6%	Plunged 150,000 won (close 879,000 won), leading the KOSPI's decline as a direct casualty of the chip-component correction
CMES Robotics	+29.9%	KOSDAQ robotics bellwether hit limit-up, symbolizing theme strength amid the index sell-off
Konan Technology	+20.1%	Jumped 2,300 won (close 13,760 won) on rotational inflows into AI growth stocks
Kumho E&C	+30.0%	Limit-up (close 9,490 won), a catalyst-driven construction winner in a down market
KNR Systems	-21.8%	Dropped 3,280 won (close 11,750 won) on profit-taking and heavy selling in KOSDAQ growth names

Domestic Schedule

🔮 Next Session Outlook

For Friday, July 31, the critical question for the KOSPI is whether it can hold support at the 5,547 level (today's low). The U.S. Advance GDP and June Core PCE figures (released late on the 30th) will steer overnight Wall Street action, which in turn will set the tone for the Korean market's open.

With the prevailing view that leverage liquidation will conclude in early August, watch for potential bargain-hunting inflows into oversold names once the liquidation overhang is digested.

• Support: KOSPI 5,550 / 5,450, KOSDAQ 640 / 620
• Resistance: KOSPI 5,700 / 5,900, KOSDAQ 660 / 677

⚠️ Investment Disclaimer

Key risks to watch: (1) AI and semiconductor valuation strain and whether the global chip correction persists; (2) the risk of foreign outflows given the elevated 1,453 USD/KRW rate; (3) additional leverage-liquidation supply in the KOSDAQ after four straight days of losses; (4) Middle East geopolitical risk from Iran and oil-price volatility; and (5) potential renewed swings in rates and the dollar following the U.S. Core PCE and GDP releases. On the other hand, Samsung Electronics' strong earnings and the FOMC's rate hold serve as downside buffers.
