Major News and Catalysts
KOSPI Hits Record 6936.99
The KOSPI closed at a record high of 6,936.99, fueled by combined foreign and institutional buying. SK Hynix surpassed a market cap of 1 quadrillion KRW, while Samsung Electronics surged 5.44%. The rally is attributed to semiconductor strength and AI investment expectations.
Commodity DRAM Price Spike
According to Digitimes, a surge in commodity DRAM prices has created an earnings gap of approximately 15 trillion KRW (approx. $10 billion) between Samsung and SK Hynix. Analysts suggest Samsung is benefiting more from commodity DRAM than HBM, providing a key catalyst for its stock price.
Samsung Foundry 4nm Turnaround
According to WCCFTech, driven by strong memory demand, Samsung’s 4nm foundry process has achieved profitability with 80% yield, securing orders from NVIDIA and Google through 2027. This performance improvement is driving stock revaluation expectations.
Barclays Raises Target Prices
Barclays raised target prices for both Samsung and SK Hynix, citing robust AI demand. SK Hynix jumped 12% on the news. However, a potential Samsung Electronics labor strike starting May 21 remains a key short-term risk.
Industry Outlook and Competition
As of May 2026, the memory market has entered a "super-cycle" due to skyrocketing AI server and HBM demand. Both companies warn that memory shortages for AI will persist beyond 2027, with clients already pre-booking years of supply. Samsung currently holds a 15 trillion KRW profit advantage over SK Hynix in commodity DRAM, while HBM3E prices are seeing a 20% increase in 2026. SK Hynix is focusing on HBM4 memory-logic integration via TSMC, while Samsung is eyeing 2027 expansion for its Taylor, Texas plant.
Global Perspective
Global optimism regarding the AI memory cycle is spreading. Bloomberg notes that TSMC, Samsung, and SK Hynix are locked in a fierce power struggle in the AI semiconductor supply chain. While OTC trading for Samsung (SSNLF) remains healthy per CNBC, KB Securities has set a domestic target price of 360,000 KRW, suggesting significant upside.
Points for Investors
- Short-term (1 week): Potential Samsung labor strike on May 21 — watch for production impact.
- Mid-term (Q1): DRAM price fluctuations, HBM4 mass production milestones, and 3nm foundry yield improvements.
- Risk Factors: ① Production disruptions from the May 21 strike, ② KRW/USD exchange rate volatility, ③ US-China export regulation impact.
