March 12 Market Closing Report — KOSPI Consolidates, KOSDAQ Rebounds

Today's Market in One Line

Large-caps took a breather while small/mid-cap tech stocks rebounded — a two-track market unfolded today.

Index Trends

KOSPI 5,583.25 (-26.70, -0.48%)

KOSPI opened slightly higher but turned lower in the afternoon as both foreign and institutional selling intensified, ultimately closing at 5,583.25, down 26.70 points from the previous day. Short-term profit-taking from the recent sharp rally weighed on the index, and caution over U.S. Treasury yield movements and a stronger dollar dampened investor sentiment.

KOSDAQ 1,148.40 (+10.72, +0.94%)

Meanwhile, KOSDAQ gained 10.72 points on the back of retail investor net buying to close at 1,148.40, within sight of reclaiming the 1,150 level. Buying flowed into growth stocks centered on AI, semiconductor equipment, and biotech, creating a contrasting trend against KOSPI.

Key Issues

Fed Official Remarks: Hawkish comments suggesting a possible slowdown in the pace of rate cuts triggered a wait-and-see mood across global markets.
USD/KRW Exchange Rate Rises: The rate touched the 1,340-won range intraday, raising concerns about foreign capital outflows and weighing on KOSPI large-caps.
Domestic AI Semiconductor Export Expectations: News of overseas orders from major fabless and equipment companies drove strength in KOSDAQ tech stocks.

Sector Performance

Market	Strong Sectors	Weak Sectors
KOSPI	Chemicals, Retail	Financials, Autos, Steel
KOSDAQ	AI/Semiconductor Equipment, Biotech, Entertainment	Construction, Shipping

AI-related semiconductor equipment stocks and next-generation biotech sectors led KOSDAQ's gains, while KOSPI financials struggled on interest rate concerns.

Tomorrow's Outlook

Tomorrow, the results of the U.S. February Consumer Price Index (CPI) release are expected to have a direct impact on the domestic market. If CPI exceeds expectations, rate cut expectations could recede and KOSPI may face further correction. Conversely, a softer reading could provide rebound momentum. KOSDAQ may continue its slightly positive trend as long as tech sector flows hold, though it is worth monitoring whether the overbought zone has been entered.
