국내 증시 주요 뉴스 브리핑 — 2026-09-13

오늘의 지수 현황

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.
