South Korea's technology-heavy Kospi Index is gradually becoming a new benchmark for global artificial intelligence trade, offering investors a gauge to assess markets before they open in the West. Bloomberg data highlights that the 60-day correlation between the Kospi and the Nasdaq 100 now stands at 0.46, three times more than its five-year average of 0.16. This correlation is fueled by leveraged trading in the stocks of SK Hynix Inc. and Samsung Electronics Co., which now act as a pre-market read-through for global investors.

A Shared Volatility Ecosystem

Ivan Feinseth, chief investment officer at Tigress Financial Partners, told Bloomberg that Korea is now part of the "same volatility ecosystem as the Nasdaq and SOX," adding that the nation is no longer "a distant emerging-market sideshow." Hani Redha, a portfolio manager at PineBridge Investments, noted, "We are all Korean investors now," as global managers track Korean shares and U.S.-listed depositary receipts. Tai Hui, chief market strategist for Asia Pacific at JPMorgan Asset Management, also stated that he had not presented Korea to his global team until this year.

Navigating the New Normal

Despite a recent 30.57% tumble to 6,516.27 points from its 52-week high of 9,385.59 points, the Kospi benchmark remains up 54.63% year-to-date and 104.40% for the year. It was also 28.02% lower over the last month, leaving fund managers to deal with leverage-driven swings. Chisa Kobayashi, Japan equity strategist at UBS SuMi TRUST Wealth Management, said, "This is the new normal investors have to accept, as long as the AI rally continues," adding that stock moves "can deviate from fundamentals" as leveraged trades on emerging markets like South Korea's Kospi become popular.

How Have Markets Performed In 2026?

The S&P 500 index has advanced 8.74% year-to-date. Similarly, the Nasdaq Composite index was up 9.83%, and the Dow Jones gained 7.78% YTD. The SPDR S&P 500 ETF Trust (NYSE: SPY) and Invesco QQQ Trust ETF (NASDAQ: QQQ), which track the S&P 500 and Nasdaq 100 respectively, were higher in premarket on Monday. The SPY was up by 0.35% at $745.88, while the QQQ advanced by 0.72% to $700.32.

Samsung Electronics Co. Ltd. has eliminated 839 positions across its U.S. display, phone, and consumer electronics operations in New Jersey and Texas as it relocates its headquarters. The layoffs impact 739 roles in Englewood Cliffs, New Jersey, and approximately 100 workers in Plano, Texas, including mobile staff. Samsung confirmed the reductions in a statement to Reuters, noting that most affected employees were offered relocation options while others were laid off.

The restructuring follows a record first-quarter operating profit of 53.7 trillion won for Samsung's chip division, driven by AI demand. However, the mobile unit faces a potential first-ever loss amid competition from Apple and Chinese rivals. The company clarified that no broad global restructuring is underway, positioning the cuts as part of a strategic realignment.

Samsung joins other technology firms, including Microsoft, Amazon, and Meta Platforms, in reducing staff while increasing investments in AI infrastructure. The relocation to Texas aligns with a broader trend of technology companies moving to states with lower taxes and business-friendly regulations, similar to moves by Tesla and Oracle.
