Today's Market in One Line

"Peak concerns + external variables = a consolidation session" — Both indices declined, with KOSDAQ's drop being particularly notable.

Index Trends

Index	Close	Change	% Change
KOSPI	5,438.87	-21.59	-0.40%
KOSDAQ	1,141.51	-18.04	-1.56%

KOSPI opened in the flat range but selling intensified in the afternoon, ultimately closing below the 5,440 level.

Foreign investors recorded slight net selling on KOSPI, while institutions maintained a neutral stance.

Key Issues

U.S. Reciprocal Tariff Concerns Resurface — The Trump administration's additional tariff mentions triggered global risk-off sentiment.
Strong USD/KRW Exchange Rate — Continued dollar strength negatively impacted foreign investor flows.
Domestic Rate Hold Expectations vs. Inflation Pressure — Bank of Korea monetary policy uncertainty heightened market volatility.
AI/Semiconductor Sector Correction — Domestic related stocks weakened across the board following global big tech share price declines.

Sector Performance

Strong Sectors

Defense/Aerospace — Steady interest on continued geopolitical tensions
Utilities (Electric/Gas) — Preference for defensive stocks
Financials (Banks/Insurance) — Expectations of benefit from maintained rate levels

Weak Sectors

Semiconductors/IT — Concentrated foreign selling, leading the index decline
Secondary Batteries — Demand slowdown concerns reignited
Bio/Healthcare — Major contributor to KOSDAQ's widened decline

Tomorrow's Outlook

In the short term, whether the 5,400 support level holds is the key focal point. Depending on U.S. market closing results and month-end position adjustment flows, volatility could increase. KOSDAQ is expected to test the 1,130 support level, and without a clear catalyst, rebound potential may be limited. Rather than aggressive chasing, a strategy of phased positioning and maintaining cash reserves appears prudent.
