South Korea Daily Briefing

Korean stocks are facing a positioning reversal as the global AI hype trade that drove Samsung Electronics and SK Hynix to record institutional inflows in 2025 and early 2026 loses momentum amid concerns about actual AI capex conversion rates. Economic Times reported that institutional buyers who purchased KOSPI on HBM memory demand optimism are reassessing their position. The DRAM and NAND cycle is still fundamentally improving, but the gap between AI-hype pricing and actual HBM volume delivery timelines is the valuation overhang that needs to compress.

Retail investors lost an estimated ₩2.3 trillion on leveraged products tied to Samsung Electronics as the AI-semiconductor correction accelerated. Livemint's coverage highlights a broader lesson for Indian and Asian retail investors: leveraged ETFs tied to single-stock themes amplify losses disproportionately during mean-reverting volatility — a 3x leveraged Samsung ETF with 35% drawdown produces 80%+ capital loss before reset. The BoK and FSS will be monitoring retail leverage exposure across KOSPI derivatives to assess systemic risk.

Korea's LH Corporation announced a 3-year plan to supply 20,000 purchase-and-lease rental homes in Seoul following a 482% surge in developer commitments since August. Simultaneously, Chosun Ilbo alleged that LH inflated construction commencement numbers using paper filings without physical work — a credibility challenge that could delay actual supply delivery. For REIT and property sector investors, the resolution of this credibility question will determine whether Seoul's rental market relief arrives in 2027 as planned.
