Amid an unprecedented technological boom in Asian markets, South Korea's KOSPI index surged 4.56% to reach a fresh all-time high of 8,457 points. The index has officially doubled its value with a 100% gain since the start of 2026, driven primarily by the semiconductor sector. Industry giants Samsung Electronics and SK Hynix powered the move, collectively representing roughly half of the total index weight.

This exceptional performance coincides with robust growth across global chipmakers, as peer Nvidia recently reported a record 262% revenue increase in its latest earnings filing. Compared to regional benchmarks, the KOSPI has significantly outperformed Japan's Nikkei 225, which posted more modest gains over the same period per market data, highlighting the concentration of liquidity in Korea's chip manufacturing hub.

Traders should watch for technical support at previous peak levels as the index maintains its record position as of May 27, 2026. Looking ahead, regional risk appetite may be influenced by Japan's Manufacturing PMI data on May 21, while the upcoming FOMC Minutes will be closely scrutinized for signals regarding global borrowing costs and liquidity.
