3 Reasons Behind the Crash | 폭락의 3가지 원인

① Broadcom AI Chip Guidance Miss 🤖

AI Semiconductor Selloff Trigger

Broadcom guided next-quarter AI semiconductor sales at $16 billion versus a $17.2 billion market estimate, sending its stock down 12.59% and triggering a global chip selloff. This hit Samsung and SK Hynix — which together make up roughly 50% of KOSPI's total market cap — extremely hard.

브로드컴의 AI 반도체 매출 가이던스가 시장 예상치를 크게 밑돌며 전 세계 반도체 주식 급락을 촉발했습니다.

② Fed Rate Hike Fears 📈

Strong US Jobs Data Pressured Rate Cut Hopes

Stronger-than-expected U.S. non-farm payrolls fueled fears of further Federal Reserve rate hikes, adding pressure on growth stocks and emerging markets including South Korea.

미국 고용지표 호조로 연준의 추가 금리 인상 우려가 커지며 신흥국 증시에 악재로 작용했습니다.

③ Geopolitical Risk + Won Weakness 🌍

Iran-Israel Tensions + USD/KRW 1,560

Iran's missile strike on Israel triggered selling across global risk assets, while the Korean won crossed the 1,560-per-dollar threshold, stoking fears of accelerating foreign capital outflows.

이란의 이스라엘 미사일 공격으로 글로벌 위험자산 매도가 촉발됐고, 원달러 환율이 1,560원을 돌파했습니다.

Should You Buy the Dip? Goldman Sachs Says Yes | 저점 매수 기회?

💡 Goldman Sachs: This Is a Buying Opportunity

Goldman Sachs expects South Korean stocks to recover after the sharp decline. Timothy Moe, the firm's chief Asia-Pacific regional equity strategist, said the selloff is likely to be remembered as a technical correction rather than the start of a prolonged downturn, noting that the underlying fundamentals supporting the market remain strong.

Goldman Sachs raised its 12-month KOSPI target to 12,000, forecasting a further 37% upside from current levels.

골드만삭스는 이번 폭락을 기술적 조정으로 보며 12개월 코스피 목표치 12,000을 유지했습니다.

⚠️ But Watch These Risk Factors

  • 📌 Record margin loans of 36.47 trillion won (~$26.9 billion) could trigger further forced selling
  • 📌 USD/KRW at 1,560 — continued won weakness raises foreign investor costs
  • 📌 Samsung + SK Hynix = 50% of KOSPI — extreme concentration risk remains
  • 📌 Fed rate hike fears could persist through summer 2026
