Samsung Electronics Stock and Market Trends — 2026-06-28
삼성전자는 28일 339,500원에 마감해 전날 대비 5.3% 하락했습니다. 외국인과 기관의 대규모 순매도(반기말 리밸런싱 및 AI 메모리 약세 우려)가 주가 급락의 주요 원인이며, SK하이닉스가 AI 메모리(HBM3E/4) 강세로 삼성전자를 시가총액 1위 자리에서 밀어낸 점도 심리 악화를 가중했습니다. 투자자들은 2분기 실적 발표 일정과 메모리 칩 가격 추이를 주시해야 합니다.

- Institutional Net Selling: Institutional investors have also been exiting Samsung Electronics over the past few days, including the 28th, with sentiment worsening due to unexpected weakness in memory chip prices.
- Plummeting Foreign Ownership: Foreign ownership of Samsung Electronics has fallen to 47.52%, the lowest level in about 13 years, highlighting a massive exit by international investors.
Key News and Catalysts
SK Hynix Overtakes Samsung Electronics as #1 Market Cap — AI Memory Strength
SK Hynix has overtaken Samsung Electronics to become the largest listed company in Korea, fueled by strong demand in the AI memory (HBM3E) market. This reflects the fruition of investments made 14 years ago (Elpida acquisition by SK Intelligence) during the AI chip boom, signaling a decline in the competitive status of Samsung’s semiconductor business.
Samsung & SK Hynix Announce $64.6 Billion Semiconductor Investment Plan
Samsung and SK Hynix have unveiled a joint investment plan of $64.6 billion (approx. 85 trillion KRW) to build new semiconductor clusters. While this is in response to surging AI demand, it may act as a burden due to capital expenditure pressure and concerns over potential memory chip oversupply in the short term.
Memory Chip Market: HBM3E Price Weakness vs. Micron’s Strong Performance
Although Micron reported a 350% year-over-year revenue increase to $41.46 billion and a 1,400% surge in net income for Q3 of fiscal year 2026, dispelling fears of an AI memory bubble, the HBM3E prices of Samsung and SK Hynix are weakening due to supply concerns. This continues to put downward pressure on Samsung’s stock.
Semiconductor Industry and Competitor Comparison
As of Q1 2026, Samsung Electronics maintained its lead in the DRAM market with a 38% share, but SK Hynix (29%) is leading the high-margin AI memory market by securing early dominance in HBM3E and HBM4. While the global memory cycle remains strong (driven by continued demand for Nvidia H200 and ASIC), excessive supply plans (expanded investments by Samsung and SK) and price weakness are expected to pressure profit margins in the second half of 2026. The key to future market share will be the speed at which SK Hynix mass-produces HBM4 and how Samsung responds.
Global Perspective
Samsung Electronics has recently become a target for massive avoidance by foreign investors, due to a combination of (1) end-of-half fund rebalancing, (2) concerns over losing AI memory market share to SK Hynix, and (3) a "panic sell" triggered by high foreign ownership (47.52%). Global media outlets like Bloomberg and CNBC continue to point out intensifying competition within the Korean semiconductor industry and concerns over memory chip oversupply.
Points for Investors to Watch
- Short-term (1 week): Foreign net selling volume from June 28 through early July — Watch for when the end-of-half rebalancing concludes. Recovery in the broader KOSPI market will be a signal for Samsung’s recovery.
- Mid-term (Q1): Q2 earnings announcement (usually late July to early August) — Keep an eye on how memory chip price weakness impacts operating profit and whether management adjusts guidance.
- Risk Factors: (1) Further decline in Samsung's market position due to SK Hynix's HBM3E/4 share expansion, (2) potential for a full-scale slowdown in AI chip demand due to global economic cooling, and (3) a technical breakdown of support levels if foreign ownership drops below 47%.
Action Items for Readers
- Check the Q2 earnings announcement schedule for SK Hynix — This will serve as a benchmark for comparing Samsung’s memory performance.
- Monitor the DXI (DRAMeXchange Index) daily — The recovery of HBM3E spot prices is a base signal for a stock rebound.
- Verify daily net buying/selling trends by foreigners via KRX — If the scale of foreign exit shrinks after the 28th, it could be interpreted as a sign of a technical bottom.
