🥜 SK Hynix in the Kospi 9000 Era: Risks to Check Before Popping the Champagne - 2026.06.19

Hello, this is Peanut from Bultagi.com. I assume everyone is raising a glass to Kospi breaking 9000? Today (19th), SK Hynix hit an intraday high of 2,891,000 won, temporarily surpassing a single-stock market cap of 2,000 trillion won ^[1]. The closing price was 2,775,000 won (+3.35%) ^[1]. The securities industry is cheering, predicting that the current valuation, which is under a PER of 7x, could reach 10x ^[10]. But is that really the case?

💼 Fundamental Check: Can We Verify the HBM4E and ADR Listing Momentum?

The core driver leading the market right now is undoubtedly HBM. SK Hynix has started supplying 12-layer samples of its 7th generation HBM4E to major customers ^[2]. They reportedly increased data processing speed by 33%, improved energy efficiency by 20%, and lowered thermal resistance by 17% by applying the Advanced MR-MUF process ^[3]. On top of this, there are expectations that the US American Depositary Receipt (ADR) listing next month will inject about $30 billion into the Seoul foreign exchange market ^[4].

Furthermore, as general memory supply shrinks due to the conversion of standard DRAM lines to HBM, device manufacturers are on high alert. Apple hinted at product price hikes, and China's Xiaomi failed to defend its profitability as its gross margin fell from 12.4% to 10.1%. Considering the forecast that a supplier-dominant market will continue until 2027, the fundamental numbers seem to provide enough justification for EV/EBITDA multiple expansion.

⚠️ Value Trap Possibility: Brain Drain and On-site Risks Require Caution

However, the stronger the bull market, the more we need to look at the flip side. Global big tech's poaching of 'K-Semiconductor' talent is becoming serious. Just today, news broke that Intel recruited former SK Hynix CEO Lee Seok-hee as Executive Vice President of Foundry ^[7]. Nvidia is offering up to 375 million won in compensation to core HBM engineers, and China's CXMT is targeting talent by offering triple their current salaries ^[8]. The outflow of top talent poses a risk of degrading R&D competitiveness and increasing costs.

Also, labor unions are strongly demanding safety measures after three chemical leak and fire accidents occurred at the Cheongju plant this month alone ^[9]. In a large-scale equipment industry, on-site risks that can lead to production disruptions or ESG-related penalties are clear valuation discount factors. We also shouldn't overlook the fact that foreign investors net sold 873.1 billion won worth of shares today (19th). A massive sell-off when supply and demand concentration is at its peak could be a signal of a short-term top.
