삼성전자 주가 및 시장 동향 — 2026-09-08
As of September 8, Samsung Electronics shares are down slightly by 0.19% intraday at 269,500 KRW. While overall large-cap semiconductor strength and net buying by foreign and institutional investors are pushing the index up, individual stocks are taking a breather. The biggest catalyst is the "depletion of memory inventory" reported by KB Securities, where supply shortages driven by explosive HBM4 demand are expected to trigger mid-to-long-term stock revaluation. <!-- /headline --> HBM4 수요 폭발...삼성전자 재고 10일분 붕괴 '공급 부족 심화' <!-- /headline -->

외국인 및 기관 매수세: During intraday trading on September 8, foreign and institutional investors engaged in net buying, pushing the KOSPI above the 7,100 mark. This improvement in supply and demand is supporting the downside for large-cap semiconductor stocks like Samsung Electronics and SK Hynix.

전일(9월 7일) 수급: On September 7, the KOSPI attempted to recover the 7,000 mark driven by a surge in large semiconductor stocks. However, in the KOSDAQ market, retail investors net-bought 186.9 billion KRW, while foreign and institutional investors net-sold 67.5 billion KRW and 131.2 billion KRW respectively, showing some profit-taking behavior.
주요 뉴스 및 촉매
메모리 재고 10일 미만 붕괴...내년 공급 부족 심화 전망
According to a recent report by KB Securities, Samsung Electronics' memory semiconductor inventory has plummeted to under 10 days. This is because the surge in AI infrastructure investment is triggering simultaneous explosive demand for HBM, server DRAM, and enterprise SSDs. This supply shortage is analyzed to drive up future semiconductor prices and serve as a core catalyst for stock revaluation.
HBM4 수요 폭증에 DRAM 공급 '바닥'...생산 캐파 대이동
HBM4 production consumes over three times more wafer capacity than conventional DRAM. As a result, Samsung Electronics has reduced general DRAM supply yet still fails to meet demand, indicating a deepening structural supply shortage in the memory market.
파운드리 4nm 물량 절반 이상 HBM4 베이스 다이로 전환
It is understood that Samsung Electronics is allocating over 50-60% of its 4nm foundry capacity to produce base dies for the 6th-generation HBM (HBM4). This is interpreted as a strategic decision to accelerate delivery speeds to major AI chip customers such as NVIDIA.
반도체 업황 및 경쟁사 비교
As of the first quarter of 2026, Samsung Electronics maintains its #1 spot in the global DRAM market with a 38% market share, followed by SK Hynix at 29%. However, in recent Q2 earnings, Micron recorded a revenue growth rate of 65.5%, narrowly edging out Samsung Electronics (63.4%). This is analyzed to be because Micron focused more on producing general server memory rather than initial HBM contracts. Furthermore, Micron plans to double its HBM production capacity to around 100,000 wafers per month by the end of 2026, making the technology and volume competition in the HBM4 market even fiercer.
글로벌 시각
According to global market research firm TrendForce, global DRAM revenue in the second quarter of 2026 reached a record-breaking $154.7 billion. This suggests that the AI infrastructure investment cycle remains strong. Meanwhile, SK Hynix is making aggressive investments, pouring a massive $720 billion into factory construction to respond to AI memory demand. Consequently, Samsung Electronics' future investment scale and HBM4 yield improvement speed have emerged as key monitoring points for global analysts.
