The KOSPI Is a Semiconductor Index Now

Overnight broke the trend: KOSPI −8%, SK Hynix −13%, Nikkei −4% — the uptrend in place since early April is gone. The handoff from capex to opex is the page: Apple, which rents its AI rather than building it, just retook the world-No.1 crown from Nvidia.

Daily Pulse — The KOSPI Is a Semiconductor Index Now

Korea tripped its circuit breaker overnight — KOSPI down 8%, SK Hynix closing −14.6%, Samsung −13.4% — and that is no longer a regional story: the KOSPI's 60-day correlation with the Nasdaq-100 sits near 0.50, its highest since 2021, because two memory names are more than half the index and data centres now take over half of global DRAM. Korea prints the first liquid read on the AI trade each morning, and this morning it printed a repricing. The US pre-market confirms the discrimination, not the panic: Nasdaq futures lower while the Dow gains on Sherwin-Williams and Coca-Cola — and Corning, which beat the quarter, trades down 16% for guiding merely in line. In-line is the new miss.
