[2026-07-24] Korea Stock Market Morning Preview | US Tech Selloff Meets Profit-Taking Risk After KOSPI's 4% Surge

📌 One-Line Summary

Following the previous session's sharp rally in both the KOSPI and KOSDAQ (+4.40%/+5.22%), an overnight plunge in US tech stocks (Nasdaq -2.15%) is expected to expose the Korean market to profit-taking pressure and heightened volatility today. A stabilizing won at the 1,470 level and supportive foreign inflows may cushion the downside.

🌙 Overnight Markets

Wall Street closed broadly lower overnight, with all three major indices in the red. The Nasdaq led the decline at -2.15%, as a tech-centered selloff dominated trading. Big-tech earnings scrutiny and stretched valuations appear to have dampened risk appetite. Because Korean equities had just reclaimed the KOSPI 7,000 mark on the back of strong semiconductor buying in the prior session, the weakness in US tech is likely to weigh on domestic chipmakers and growth names today.

Index	Close	Change
Dow Jones	51,711.65	-0.97%
S&P 500	7,408.30	-1.21%
Nasdaq	25,137.69	-2.15%

That said, the previous domestic session saw net buying from both foreign and institutional investors, along with the activation of a buy-side sidecar — supportive flows that should help limit today's downside. For reference, the KOSPI closed the prior session at 7,096.89 (+4.40%) and the KOSDAQ at 790.28 (+5.22%).

💱 FX & Commodities

Item	Level
USD/KRW	1,474.11
Bitcoin (BTC)	$65,097.99

The won stood at 1,474.11 per dollar, easing from recent levels above 1,500 and creating a more favorable backdrop for foreign capital inflows. A steadier currency supports the return of domestic retail funds from overseas markets and the continuation of foreign net buying. Bitcoin traded near $65,000, reflecting the broader tone of risk sentiment. Middle East geopolitical risk remains a latent variable for oil prices and warrants ongoing monitoring.

🔥 Today's Key Themes & Sectors

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

A surge in SK Hynix's ADR and broad semiconductor strength drove the index higher in the prior session. However, following the overnight plunge in US tech, profit-taking may emerge today, so investors should watch for heightened volatility. Whether the weakness in US chip names spills over into Korea's large-cap semiconductors is likely to be the decisive variable for today's index direction.

2. FX Beneficiaries & Foreign Net-Buying Plays — Watch

With the won stabilizing at the 1,470 level and foreign investors returning, sentiment is improving. Large-caps that attract concentrated foreign flows remain worth watching. The direction of domestic retail overseas funds and foreign trading activity is the key swing factor.

3. Rate- & Policy-Sensitive Financials — Watch

The outcome of the ECB's overnight policy meeting (main refinancing rate held at 2.40%), combined with caution ahead of the Bank of Korea's rate decision, puts the spotlight on rate-sensitive sectors such as banks and brokerages. Inflation and FX trends amid rate-hike concerns may sway sentiment for financial stocks.

🎯 Scenario Outlook

📈 Bull Case

Currency stability and continued foreign net buying limit the impact of US weakness, allowing large-cap semiconductors to recover their losses and the KOSPI to hold firmly above the 7,100 line.

➡️ Neutral Case

Profit-taking after the prior surge and the drag from US weakness offset each other, leaving the KOSPI to fluctuate within a 7,000–7,100 consolidation range — a breather session.

📉 Bear Case

The US tech plunge spreads to Korean chipmakers and growth stocks, and concentrated profit-taking pushes the KOSPI below 7,000, with the KOSDAQ also slipping under the 780 line in a corrective move.

Index	Support	Resistance
KOSPI	7,000	7,200
KOSDAQ	770	810
