Key News & Catalysts
KOSPI Breaks 7,800 — 'Burning Samsung & SK Hynix'
The KOSPI index surpassed the historic 7,800 mark in early May 11 trading, triggering the buy-side circuit breaker amid concentrated buying. Samsung Electronics and SK Hynix led the gains, with target prices of "500,000 won for Samsung and 3 million won for SK Hynix" gaining such prominence that KBS News covered the market sentiment.
AI Inference Boom — HBM Demand Surge Accelerates Memory Race
Digitimes reported on May 11 that the AI inference boom is accelerating memory market competition. With production running near full capacity, certain DDR5 product margins have improved, while next-gen HBM has emerged as a key variable. Samsung is positioned in a competitive dynamic chasing SK Hynix in this race.
SK Securities Sets 500,000 Won Target — "Structural Shift in AI Memory Demand"
According to Korea Economic Daily, Samsung Electronics closed at 268,500 KRW on May 8, surging roughly 20% in a week. SK Securities issued a 500,000 KRW target price, citing "structural change in AI memory demand" as rationale. KB Securities maintains a "Buy" rating with a 360,000 KRW target, noting the current price trades at a PER of 4.7x on FY2026E earnings—a cheap valuation level.
Semiconductor Outlook & Competitive Comparison
Samsung Electronics has decided to accelerate the groundbreaking of a new megafab within its Pyeongtaek semiconductor campus by over six months in response to surging AI memory demand, with total investment reaching 120 trillion KRW (approximately $82.7 billion). SK Hynix is similarly accelerating capacity expansion, with reports emerging that major big tech firms are proposing funding support for SK Hynix's new production lines. In the HBM market, SK Hynix leads in HBM3E supply, while Samsung is preparing a counteroffensive through a proprietary approach of integrating NAND technology (logic circuits below the cell) into next-gen DRAM. SK Hynix is responding with vertical stacking, creating a dynamic where both companies pursue divergent technological paths to compete for AI memory dominance. Both Samsung and SK Hynix have warned that AI-driven memory supply shortages could persist through 2027 and beyond, with some customers already reserving multi-year supply volumes.
Global Perspective
CNBC reported on May 6 that Samsung Electronics' announcement of over 8x operating profit growth in Q1 was followed by a 15%+ stock surge, pushing market cap past the $1 trillion mark. Dong-A Ilbo quoted expert opinion that "Samsung Electronics and SK Hynix may still be undervalued from foreign investor perspective," citing the fact that these two companies account for over 60% of KOSPI's total operating profit while representing just 45% of market capitalization. Maeil Business Newspaper conveyed expert sentiment that "Samsung's PER is at historic lows and selling now is a mistake," emphasizing the appeal of AI-driven semiconductor high-growth phases and Korea market re-rating momentum.
Investment Focus Points
- Short-term (1 week): Monitor major securities firms' Q2 earnings updates and potential additional target price revisions. Confirm supply-demand stabilization post-circuit breaker activation.
- Medium-term (3 months): Samsung's qualification for NVIDIA supply chain HBM4 final delivery (qualification pass) is the critical variable. Track acceleration progress of Pyeongtaek megafab groundbreaking (6-month acceleration) and HBM market share competition with SK Hynix.
- Risk Factors: ① AI demand slowdown or US-China trade tensions reigniting semiconductor export restrictions — Samsung's China revenue dependency is a variable; ② Short-term profit-taking pressure from recent steep rally (~20% in one week) and foreign investor supply volatility.
Reader Action Items
- Confirm SK Hynix Earnings Release Schedule: Use SK Hynix Q2 earnings announcements—particularly HBM revenue proportion and HBM4 mass production status—as leading indicators for Samsung Electronics outlook.
- Monitor DRAMeXchange Spot Prices: DDR5 and HBM spot price trends lead Samsung-SK Hynix margin changes; recommend weekly review at [].
- Daily Foreign Investor Flow Tracking: Check foreign investor holdings and net purchase amounts daily at sources like Daum Finance to catch supply-demand reversal signals.
