Domestic Markets Plunge on Foreign and Institutional Selling Despite Global Tech Rebound

Key Takeaways
  • U.S. markets saw the Nasdaq rebound 1.11% on bargain hunting in beaten-down tech stocks, despite lingering concerns over AI-related debt.
  • South Korean markets failed to ride the U.S. tech rebound, with the KOSPI dropping 3.73% and KOSDAQ sliding 3.33% amid dual net selling by foreign and institutional investors.
  • The KRW/USD exchange rate ended slightly lower at 1,327.60 KRW, reflecting relatively contained volatility in the foreign exchange market.
Highlights

KOSPI

The KOSPI retreated over 3% to 5,552.74 amid heavy selling by foreigners and institutions, weighed down by profit-taking and risk-off sentiment in large-cap semiconductor stocks.

Highlights

KOSDAQ

The KOSDAQ declined 3.33% to close at 781.97, reflecting dampened sentiment across small- and mid-cap growth stocks.

Highlights

NASDAQ

The Nasdaq rose 1.11% to 26,430.89, though market caution persists over debt burdens and profitability of AI infrastructure investments ahead of major tech earnings.

Today's Watchlist
  • Quarterly earnings and profitability guidance on AI infrastructure capex from major tech firms such as Meta and Tesla
  • Potential shift in foreign and institutional supply-demand dynamics and support-level defense in domestic equities
  • U.S. Treasury yield trajectories and whether the KRW/USD rate can stabilize in the 1,320s range
Risk Note

Concerns persist over debt accumulation and monetization delays relative to heavy capex in AI-related firms, leaving open the risk of heightened market volatility depending on upcoming earnings results.
