[2026.06/15~06/19] Korea Stock Market Weekly Preview

📌 Next Week Outlook Summary

After a historically volatile week, the KOSPI clawed back above the 8,000 mark. Next week brings a 'monetary policy super week' headlined by the Wednesday-night (KST: early Thursday 6/18) FOMC decision, with the BOJ, BOE and SNB all reporting. The Fed's dot plot and the tone of Chair Powell's remarks are expected to set the market's direction.

📊 Last Week Market Summary

Last week (6/8–6/12), Korean equities opened the week in free fall on the back of a panic sell-off in U.S. semiconductor names, but a powerful rebound followed and the KOSPI reclaimed the 8,000 level. The KOSDAQ saw even sharper swings yet finished the week with a strong gain.

Index	Week Open	Week Close	Week High	Week Low	Week Volume (10K)	Weekly Change
KOSPI	8,048.09	8,123.62	8,434.40	7,394.46	233,375.3	+0.94%
KOSDAQ	959.61	1,029.05	1,049.70	908.46	313,946.2	+7.24%

The KOSPI swung more than 1,000 points between its weekly high of 8,434.40 and low of 7,394.46, delivering one of the most volatile weeks on record. The KOSDAQ posted a robust weekly gain of +7.24%, settling at 1,029.05 to hold above the 1,000 line. (Volume figures shown in units of 10,000 shares.)

Daily Performance

Date	KOSPI Close	Change	KOSDAQ Close	Change
Mon 6/08	7,484.41	-8.29%	911.39	-9.08%
Tue 6/09	8,096.93	+8.18%	967.81	+6.19%
Wed 6/10	7,730.82	-4.52%	951.63	-1.67%
Thu 6/11	7,763.95	+0.43%	996.93	+4.76%
Fri 6/12	8,123.62	+4.63%	1,029.05	+3.22%

Monday's panic sell-off in U.S. chip names dragged the KOSPI down -8.29% and the KOSDAQ -9.08% at the open. Sentiment then reversed sharply on Tuesday as the KOSPI staged a record-setting +8.18% rebound. Profit-taking pushed the market lower again on Wednesday, but a two-day recovery on Thursday and Friday left the week in positive territory. With daily moves of roughly ±8% recurring throughout the week, elevated volatility may persist around next week's central-bank events.

🌙 Global Market Trends

Last Friday, all three major U.S. indices closed higher, partially unwinding the early-week shock from the semiconductor sell-off. Lingering momentum in AI demand and rising memory prices helped steady sentiment.

Index	Close	Change
S&P 500	7,431.46	+0.50%
Nasdaq	25,888.84	+0.31%
Dow Jones	51,202.26	+0.70%

💱 FX & Commodities

Item	Level	Note
USD/KRW	1,517.89	Elevated, holding in the 1,500s
WTI Crude	N/A	Collection error — excluded

The Korean won traded at 1,517.89 per dollar, still parked in the elevated 1,500-won zone and stoking concerns over foreign capital outflows. Despite intervention by the authorities, the currency remains volatile near the psychologically important 1,550 level, and whether the won stabilizes will be the key variable for foreign flows next week. With cumulative foreign net selling this year reaching roughly KRW 110 trillion, the direction of the currency is expected to bear directly on the market's underlying strength. (WTI crude data was excluded due to a collection error and warrants separate monitoring.)

🔥 Key Themes to Watch Next Week

1. Semiconductors & Memory (Watch)

With memory prices firming and AI investment momentum intact, large-cap chip names such as Samsung Electronics and SK hynix are likely to steer the index. The key question is whether the rebound from the early-week panic sell-off can extend, in a tug-of-war between memory-price/AI momentum and profit-taking pressure.

2. Rate-Sensitive Names into the FOMC (Caution)

Depending on the FOMC outcome in the early hours of 6/18 KST (a hold at 3.75% is widely expected) and the accompanying dot plot, volatility in growth and rate-sensitive sectors may widen. A wait-and-see stance is likely to prevail until the result is confirmed.

3. FX & Exporters (Watch)

The elevated won (in the 1,500s) is supportive for exporters such as automakers and shipbuilders, but a headwind for foreign flows. The currency's direction could drive sector differentiation between exporters and domestic/rate-sensitive names.

4. Big-Tech Earnings Plays (Upside Expected)

Expectations for big-tech second-quarter earnings, which begin in earnest next week, remain intact. Combined with momentum from AI-related ADR listings, related names may show strength.

🎯 Scenario Outlook

📈 Bull Case

If the FOMC delivers a dovish dot plot and commentary while the won stabilizes below 1,500, foreign selling could ease, allowing the KOSPI to test 8,400 and the KOSDAQ 1,050. This would mark a renewed rally led by large-cap semiconductors.

⚖️ Neutral Case

If the FOMC holds with a neutral tone and the market digests the outcome, the KOSPI is expected to trade in a 7,900–8,300 range. With the won holding in the 1,500s, sector rotation is the likely theme.

📉 Bear Case

A hawkish FOMC signal, a BOJ hike shock, or a renewed break above 1,550 on the won could accelerate foreign selling, dragging the KOSPI toward 7,700 and the KOSDAQ toward 980. A recurrence of last week's high-volatility regime is a risk.

📅 Next Week's Economic Schedule

June 15–19 is a 'super week' of concentrated central-bank policy decisions across major economies. Anchored by the U.S. FOMC in the early hours of 6/18 KST, the BOJ, RBA, BOE and SNB decisions all line up back-to-back, which could amplify volatility.

ECB President Lagarde also speaks on Mon 6/15 at 16:15 KST (Medium impact).

📋 Earnings & Schedule Watch

The week's biggest pivot is the FOMC in the early hours of 6/18. A hold at 3.75% is all but a foregone conclusion, but the dot plot (the rate path for the rest of the year) and the tone of Chair Powell's remarks will be the decisive variables for market direction.
The BOJ on 6/16 is seen as a candidate for a further rate hike; a hike could drive yen strength and ripple across Asian equity markets.
The big-tech second-quarter earnings season gets underway, set to be a swing factor for AI-related names.

⚡ Investment Checkpoints

6/18 FOMC dot plot & Powell's tone — signals on this year's rate path will steer growth and rate-sensitive names.
Whether USD/KRW stays anchored in the 1,500s — a renewed break above 1,550 risks accelerating foreign selling, while a move below 1,500 would raise hopes of improving flows.
Early-week semiconductor volatility — a tug-of-war between memory prices/AI momentum and profit-taking pressure.
BOJ rate decision — watch for spillover into the yen and Asian equities in the event of a hike.
Foreign flows — whether this year's cumulative ~KRW 110 trillion of net selling shows signs of easing.
