[2026.06/08~06/12] Korea Stock Market Weekly Preview | US CPI & SpaceX IPO Set the Tone After 8% Overnight Futures Plunge

📌 Next Week Outlook Summary

A panic sell-off in US semiconductor stocks and an -8% plunge in KOSPI 200 overnight futures point to a sharply lower open for Korean equities next week. The US May CPI release on June 10 and the SpaceX IPO on June 12 are expected to be the decisive turning points for market direction.

Welcome to your preview of the Korean stock market for the week of June 8–12, 2026. Just days after flirting with the 9,000 mark, the KOSPI reversed hard in the back half of last week and slid to the 8,160 level. With Wall Street tumbling over the weekend and overnight futures plunging, next week is shaping up to be one that demands disciplined risk management from international investors in Korean stocks.

📊 Last Week Market Summary

The KOSPI opened the week strong, reaching 8,788 (+3.68%) near record territory, but reversed sharply later in the week to close at 8,160.59, posting a weekly return of -3.83%. The KOSDAQ fared worse, falling to 1,002.44 for a weekly loss of -6.56%. The wide intraday range on the KOSPI (high 8,933 to low 8,038) underscores how quickly '9,000-point' optimism flipped into selling on profit-taking and external headwinds.

Index	Weekly Open	Weekly Close	Weekly High	Weekly Low	Weekly Change	Weekly Volume
KOSPI	8,485.67	8,160.59	8,933.62	8,038.10	-3.83%	216,982.2만
KOSDAQ	1,072.77	1,002.44	1,082.75	992.80	-6.56%	295,714.4만

Daily Performance

Date	KOSPI Close	KOSPI Change	KOSDAQ Close	KOSDAQ Change
06/01 (Mon)	8,788.38	+3.68%	1,050.03	-2.30%
06/02 (Tue)	8,801.49	+0.15%	1,026.03	-2.29%
06/04 (Thu)	8,639.41	-1.84%	1,049.73	+2.31%
06/05 (Fri)	8,160.59	-5.54%	1,002.44	-4.50%

After starting near record highs, the KOSPI cratered -5.54% in a single session on Friday (6/5), wiping out all of the week's gains. The KOSDAQ also dropped -4.50% on Friday, barely holding the 1,000 line.

🌙 Global Market Trends

Wall Street sold off hard over the weekend as a strong US jobs report revived fears of a Fed rate hike, triggering a panic sell-off centered on semiconductor names. All three major indices fell sharply. The Nasdaq plunged -4.18% (roughly -4.7% on the week), and the S&P 500 posted its first weekly decline in about 10 weeks. Crucially, KOSPI 200 overnight futures closed down 8%, dramatically raising the odds of a sharply lower open for Korean equities on Monday (6/8).

Index	Close	Change
S&P 500	7,383.74	-2.64%
Nasdaq	25,709.43	-4.18%
Dow Jones	50,866.78	-1.35%

💱 FX & Commodities

The USD/KRW exchange rate remains elevated at 1,558.8, climbing on foreign selling and risk-off sentiment. A weaker won is a headwind for foreign fund flows, and with the government signaling readiness to take necessary measures against FX volatility, the market is also wary of potential intervention by the foreign exchange authorities. The collected WTI crude figure (USD 7.32) appears to be a data anomaly, so interpretation is withheld for now.

Item	Value	Note
USD/KRW	1,558.84	Elevated; pressures foreign flows
WTI Crude	To be confirmed	Data anomaly — interpretation withheld

🔥 Key Themes to Watch Next Week

1. Semiconductors & AI (Caution)

The panic sell-off in US chip stocks and Broadcom's slump make near-term volatility in Korean market leaders such as Samsung Electronics and SK Hynix all but inevitable. That said, the underlying AI investment momentum remains intact, so an oversold bounce is possible — warranting caution in both directions.

2. FX Beneficiaries & Defensive Plays (Watch)

With USD/KRW in the 1,550 range, watch for rotation into exporters such as autos and shipbuilders, as well as defensive names in dividends and telecom. These could serve as relative safe havens in a volatile market.

3. Aerospace & the SpaceX Value Chain (Watch)

Ahead of the SpaceX 'IPO of the century' on June 12, concerns over a liquidity 'black hole' are growing, and theme volatility in domestic aerospace and satellite-related stocks is likely to come into focus. Investors should watch how global fund concentration affects supply-demand dynamics in the Korean market.

4. Rate-Sensitive Growth Stocks (Caution)

With US CPI expected to rebound (forecast 4.2%) and fears of a Fed rate hike, high-valuation growth names and small/mid-cap KOSDAQ stocks face correction pressure that calls for caution.

🎯 Scenario Outlook

📈 Bull Scenario

After a sharply lower Monday open, bargain hunting may emerge on oversold conditions and intact AI momentum. If the June 10 US CPI comes in below consensus (4.2%), easing inflation concerns could help the KOSPI attempt a recovery toward the 8,400 level.

➖ Neutral Scenario

The market gaps down to partly reflect the overnight futures drop, then trades in an 8,000–8,400 range, oscillating in a wait-and-see mode as investors await events such as the CPI print and the SpaceX listing.

📉 Bear Scenario

If the US CPI overshoots and Fed rate-hike fears materialize, combined with foreign selling and a surging won, the KOSPI could break below 8,000 and the KOSDAQ could lose the 980 level in a further correction.

📅 Next Week's Economic Schedule

6/11 (Thu)	21:30	US	PPI m/m	0.7%	1.4%
6/11 (Thu)	21:30	US	Core PPI m/m	0.5%	1.0%
6/11 (Thu)	21:45	Eurozone	ECB Press Conference	-	-
6/12 (Fri)	15:00	UK	GDP m/m	-	0.3%

The biggest pivot point of the week is the US May CPI on Wednesday, June 10. With consensus at 4.2% y/y — a rebound from the prior 3.8% — the outcome could sharply reset market expectations for the Fed's rate path. The Thursday PPI release and the ECB policy meeting (where the main refinancing rate is expected to be raised from 2.15% to 2.40%) are also key variables for global direction.

⚡ Investment Checkpoints

• Size of Monday's gap-down and intensity of foreign net selling — the first thing to watch is whether the -8% overnight futures move is fully reflected.
• June 10 US CPI result — the key trigger for a reassessment of the Fed's rate path.
• Whether USD/KRW breaks above 1,560 — raising the risk of FX intervention and accelerated foreign outflows.
• Supply-demand impact of the SpaceX listing — monitor potential capital outflows from the Korean market amid 'black hole' concerns.
• The inflection point between bargain hunting and further downside in oversold semiconductor and AI leaders.
