South Korea’s KOSPI market saw a notable shift in the first half of 2026, with foreign investors re-emerging as the primary net buyers. A combination of expectations for U.S. Federal Reserve rate cuts, a weaker dollar, and improving semiconductor earnings drove foreign capital toward Korean equities. In particular, AI-driven demand for high-bandwidth memory (HBM) provided a direct structural tailwind for Korean chipmakers, signaling that this was not a short-term theme but a reflection of deeper structural change.
However, not all sectors benefited equally. Foreign capital moved with clear selectivity, and understanding exactly where it concentrated is the starting point for building a second-half investment strategy. This article breaks down the H1 2026 foreign net-buying patterns and identifies the most promising sectors for the remainder of the year.

This weekly plan was finalized after duplicate-checking against recently published topics. Today’s Tuesday piece covers the economy axis of this week’s lineup, focusing on foreign capital flows and sector strategy for H2 2026.
H1 2026 Foreign Net Buying: Scale and Background
Based on Korea Exchange (KRX) data, foreign investors significantly expanded their cumulative net-buying positions in KOSPI from January through May 2026. In Q1, concentrated buying in the electronics sector — led by semiconductor names — dominated the flow. By Q2, the breadth had expanded to include financials, energy, and defense.
Three main factors drove this trend. First, Fed rate-cut expectations: as U.S. inflation eased in early 2026, markets priced in at least one cut for the first half of the year, weakening the dollar and pushing capital into emerging markets including Korea. Second, corporate earnings improvement: Samsung Electronics beat Q1 operating profit estimates, while SK Hynix posted near-record quarterly results on the back of HBM shipment growth. Third, geopolitical stabilization: partial easing of U.S.-China trade tensions and strengthened Korea-U.S. relations led foreign investors to reassess Korea as a preferred emerging market in risk-on environments.
Four Sectors That Captured Foreign Capital in H1
1. Semiconductors & IT: Still the Dominant First Choice
Samsung Electronics and SK Hynix led all sectors in foreign net buying. SK Hynix consistently ranked among the top net-bought stocks as global hyperscalers accelerated data center investments, driving explosive HBM demand. Samsung’s position was more volatile due to concerns about HBM3E ramp-up timing, but as its H2 production schedule was confirmed, buying interest returned.
2. Autos & Batteries: Recalibrating EV Transition Pace
Hyundai and Kia maintained relatively stable foreign positioning. Their hybrid vehicle strategy allowed them to defend both sales volumes and profitability in an environment where EV adoption rates were slowing in the U.S. and Europe. The battery sector saw some net selling in H1 on EV demand concerns, but improving ESS demand and ongoing IRA benefits in North America are shifting H2 expectations more favorably.
3. K-Defense: Rising Foreign Interest on Structural Export Growth
Hanwha Aerospace, Hyundai Rotem, and LIG Nex1 expanded defense export contracts across Eastern Europe, the Middle East, and Southeast Asia, prompting a revaluation of their earnings and multiples. Foreign investors began viewing Korean defense as a unique combination of defensive characteristics and structural growth potential.
4. Financials: Transitioning from Rate-Hike Beneficiary
While rate-cut expectations made banks more cautious to watch, strong capital ratios and enhanced shareholder return policies (buybacks, dividends) kept foreign investors engaged, particularly in names like KB Financial and Shinhan with clear return-of-capital commitments.
Key Sectors to Watch in H2
AI infrastructure, K-defense and nuclear exports, and biopharma technology licensing are the three structural growth axes most likely to sustain foreign interest in H2. Consumer/beauty stocks remain more dependent on China recovery velocity and warrant selective positioning.
Strategy for Individual Investors
Foreign net buying is a useful reference signal but should not be followed blindly. Use it as a sector-allocation guide for a 6–12 month horizon rather than as a short-term trading trigger. Pair it with earnings revision trends, sector fundamentals, and macro indicators like the DXY and U.S. rate path to make better-calibrated positioning decisions.
