KOSPI Drops 3.26% as Foreigners Sell KRW 3.29 Trillion and Defense Stocks Rise

작성자:K jumma 마지막 수정일:

The KOSPI lost 225.54 points, or 3.26%, to close at 6,684.37 on September 14. The KOSDAQ fell 1.69% to 806.79. The most revealing number was KRW 3.289 trillion of foreign net selling in the KOSPI. Market breadth confirmed that this was not a correction confined to a few mega-caps: 563 KOSPI stocks declined versus 309 advancers, while the KOSDAQ recorded 1,115 decliners against 545 advancers.

A broad risk reduction, not just chip profit-taking

The KOSPI opened at 6,692.61, recovered as far as 6,773.97, and then weakened again to finish not far above its 6,654.82 intraday low. The KOSDAQ briefly broke below 800 with a low of 799.77. Domestic individuals bought a net KRW 2.968 trillion in the KOSPI, but that was not enough to absorb combined selling by foreigners and institutions. Foreigners and institutions also sold the KOSDAQ.

Friday’s U.S. rebound did not remove the two pressures that matter most for Korea’s valuation-sensitive market. Brent crude still settled at $104.61 a barrel, and the U.S. 10-year Treasury yield ended near 4.97% after trading through 5% intraday. U.S. August CPI rose 0.4% month on month and 3.4% year on year, with the energy index up 16.3% from a year earlier. With the September 15–16 FOMC meeting one day away, Korean investors treated the combination of expensive oil and high long yields as a continuing margin and discount-rate shock.

Liquid mega-cap chips became the source of funds

Samsung Electronics fell about 4% and SK hynix dropped more than 6%. Their combined index weight amplified the decline, while the KOSPI 200 lost 3.61%. This does not necessarily signal an immediate collapse in the earnings outlook for Korean memory. It is more consistent with foreign investors cutting liquid, high-beta exposure first as oil, rates and currency volatility remain elevated.

Defense moved in the opposite direction. Hanwha Aerospace gained more than 5% in the regular session, while Hanwha Systems and LIG Defense & Aerospace also rose. A prolonged conflict raises supply-chain and inflation risks, but it also extends the visibility of defense orders and export backlogs. This is why defense, rather than refiners, ranks first in today’s Focus Map: S-Oil and SK Innovation declined, showing that high crude prices are not an automatic positive for every energy stock.

Banks, shipping and telecoms offered selective shelter

Woori Financial, Hana Financial and KB Financial advanced. Long yields near 5% hurt long-duration growth valuations, but they support the market’s net-interest-margin and earnings-defense narrative for banks. Visible capital returns added another layer of protection during a day of heavy index selling.

HMM and Pan Ocean also gained. Higher fuel costs are a headwind, yet the market gave more weight to the possibility of rerouting and freight-rate premiums if Middle East disruption persists. KT and LG Uplus rose as investors sought stable cash flow and dividends. Neither shipping nor telecom delivered a universal sector rally, so these moves should be read as selective refuges rather than new broad bull trends.

KSI view: follow the quality of flows before the size of a rebound

The first test for the next session is whether the KOSPI can hold the 6,655 area and reclaim 6,700. More important is whether foreign selling falls materially from today’s KRW 3 trillion-plus pace and whether Samsung Electronics and SK hynix stabilize before the index. Brent above $100, the U.S. 10-year near 5%, and USD/KRW around 1,346 remain the key macro pressure points ahead of the FOMC decision.

If strength in defense and banks broadens into shipping and telecoms, the market is likely pricing high oil and high rates as persistent conditions. If oil and yields settle while foreign chip selling quickly fades, the selloff will look more like a liquidity-driven de-risking event than a fresh earnings downcycle. At this stage, who is buying and what is holding the index matter more than the headline size of any rebound.
