[2026-07-17] Korea Stock Market Morning Preview | KOSPI Oversold Rebound vs AI Peak-Out Fears

📌 One-Line Summary

After plunging more than 6% in the previous session, the KOSPI is expected to attempt an oversold technical rebound today. However, overnight weakness in US semiconductors and lingering "AI peak-out" concerns may cap the upside, setting up a high-volatility session between the 7,000 resistance and 6,700 support levels.

🌙 Overnight Markets

US equities closed lower on Thursday as semiconductor weakness dragged the indices down. The Nasdaq fell the most, the S&P 500 posted a moderate decline, and the Dow held up relatively well — a clear sign of sector-by-sector differentiation. In particular, Morgan Stanley's "AI peak-out" (AI investment top) warning combined with a sharp drop in SK Hynix's US ADR weighed heavily on sentiment toward large-cap semiconductor names.

Index	Close	Change
Nasdaq	25,881.95	-1.47%
S&P 500	7,533.77	-0.51%
Dow Jones	52,552.97	-0.20%

The fact that the Dow held firm at -0.20% while the Nasdaq led the declines suggests possible rotation into cyclical and value stocks outside the semiconductor space. Because Korean stocks suffered an "independent crash" without benefiting from the relative resilience seen in US markets, today is likely to see a tug-of-war between an oversold rebound impulse and the continuation of US chip weakness.

💱 FX & Commodities

Item	Close	Note
USD/KRW	1,477.76	Elevated FX regime persists
Bitcoin	$63,983.99	Risk-appetite barometer
WTI Crude	Data unavailable	Collected figure abnormal, excluded

The won/dollar rate stands at 1,477.76, still in the elevated high-1,470s zone that remains a headwind for foreign inflows into Korean equities. That said, recent market commentary noting the won firmed slightly back toward the 1,480 area suggests the pressure for further sharp won depreciation is easing somewhat. Bitcoin, hovering near $64,000, continues to serve as a barometer of risk appetite — watch for whether its rebound moves in tandem with sentiment toward domestic growth stocks. (Today's WTI crude figure from the data feed was clearly abnormal and has been excluded.)

🔥 Today's Key Themes & Sectors

1. Semiconductors (SK Hynix / Samsung Electronics) — Caution

US Nasdaq chip weakness, the sharp drop in SK Hynix's ADR, and the "AI peak-out" debate are converging to drive heightened volatility in large-cap semiconductor names. This is the pivotal variable for today's market, where bargain-hunting on the oversold pullback and further downside adjustment cross paths. The opening-price action of these names is expected to act as the directional signal for the broader index.

2. Oversold Rebound Plays — Watch

The KOSPI's -6.37% plunge in the previous session pushed the market into oversold territory. Historically, technical rebounds have frequently followed sidecar and circuit-breaker triggers, so watch for potential bargain-buying inflows from a short-term trading perspective.

3. Rate-Sensitive Sectors (Financials / Construction) — Watch

Ahead of the Bank of Korea's rate decision, a narrowing Korea-US rate gap and easing concerns over Fed tightening are coming into focus. Watch for a rotation of funds fleeing semiconductors into rate-sensitive and defensive sectors.

4. Low-PBR & Cyclical Value Stocks — Watch

Given the Dow's relative resilience overnight, there is room for rotation into earnings- and dividend-based value stocks if the concentration in semiconductors eases.

🎯 Scenario Outlook

📈 Bull Case

Despite US chip weakness, the Dow held firm — so rebound buying against the previous session's excessive plunge, alongside foreign bargain-hunting, may drive the KOSPI to attempt a recovery toward the 6,900–7,000 zone. This is the scenario where the post-sidecar/circuit-breaker rebound "learning effect" kicks in.

➡️ Neutral Case

Large-cap semiconductors extend their weakness, but oversold rebound plays and sector rotation offset the drag, leaving the KOSPI to fluctuate around the 6,800 level before settling flat after a bout of heightened volatility — a phase of searching for direction.

📉 Bear Case

"AI peak-out" fears spread again and index heavyweights such as SK Hynix and Samsung Electronics fall further, pushing the KOSPI below the 6,700 level. If elevated FX and foreign outflows compound the move, sentiment could deteriorate further.

⚡ Key Checkpoints for Today

• Opening-price action of semiconductor heavyweights (SK Hynix, Samsung Electronics) — the rudder deciding oversold rebound vs. further downside
• Early-session program trading and foreign flows (whether the elevated 1,477 FX level persists)
• Whether the KOSPI breaches the 7,000 (psychological resistance) and 6,700 (support) levels, and the possibility of a renewed sidecar trigger
• Follow-up news on the "AI peak-out" theme and the trajectory of the US Philadelphia Semiconductor Index

Key Levels: KOSPI support 6,700 / resistance 7,000; KOSDAQ support 770 / resistance 810.
