South Korea Daily Briefing

SK Hynix announced a ₩38tr ($28.7B) share repurchase — the largest in Korean corporate history — with shares surging on the August 19 announcement. The timing signals management confidence that HBM3E/HBM4 demand from NVIDIA's GB200/Blackwell platform will sustain revenue through at least FY2027. Samsung SDI and LG Energy Solution have noted AI datacenter battery backup demand as a secondary HBM-adjacent theme. The buyback also limits chaebol governance discount pressure — a structural improvement for KOSPI's multiple.

KEP surging 3.98% — identical to the industrials sector composite — signals Korea's electricity infrastructure is being repriced as an AI infrastructure play. Hyperscaler datacenters in Korea consume increasing shares of KEP's grid capacity, and capacity expansion contracts are being locked at premium rates. If AI datacenter power demand sustains, grid storage (LG Energy, Samsung SDI) and transmission infrastructure both benefit as co-themes. Watch KEP for whether it holds: sustained outperformance signals a structural shift, not a one-day event.

Chosun Ilbo flagged NVIDIA results and a US Federal Reserve speech as twin catalysts that will 'determine KOSPI direction.' The framing is correct: NVIDIA's GB200 shipment guidance maps directly to SK Hynix and Samsung Semiconductor's HBM revenue visibility for H2 2026. Any Fed hawkish surprise would hit KRW and compress KOSPI's multiple. The market is running hot at +3.31% — a double miss (soft NVIDIA guidance + hawkish Fed) would be a sharp reversal. Position accordingly ahead of US close.
