국내 증시, 코스피 7000선 붕괴 브리핑
On Friday, September 11, the KOSPI dropped 1.76% to close at 6,909.91, sliding back below the 7,000 threshold due to escalating Middle East tensions and rising US Treasury yields. The KOSDAQ also fell 1.9% to 820.64, pressured by net selling from foreign investors and profit-taking in the semiconductor sector. Meanwhile, a roughly 90% probability of a rate hike by the US Federal Reserve this week is fueling a risk-off sentiment across the broader market.

오늘의 지수 현황

| 지수 | 종가 | 전일비 | 등락률 | 비고 |
|---|---|---|---|---|
| KOSPI | 6,909.91 | -124.01 | -1.76% | 7,000선 재하회, 반도체 차익실현 |
| KOSDAQ | 820.64 | -16.28 | -1.9% | 중소형주 동반 약세 |

After briefly recovering the 7,000 mark with a 3.33% gain last week, the KOSPI turned downward during trading on September 11, slipping into the low 6,900s. This decline was driven by a combination of unfavorable macroeconomic variables, including a surge in international crude oil prices (Brent crude breaking past $107) and the US 10-year Treasury yield hitting 4.97%. Notably, sector differentiation was pronounced, with major semiconductor stocks—which had recently led the rally—undergoing corrections, while only select shipbuilding stocks managed to defend against the losses.

전문가 코멘트
Mirae Asset Securities analyst Seo Sang-young diagnosed that "the Korean stock market remains undervalued compared to historical valuations, trading around a 9P PER level." However, because macroeconomic variables (interest rates and oil prices) currently have a greater impact than corporate earnings, it is necessary to approach the recovery of the 7,000 index level with patience.
