TOP 10 Market Sectors and Stocks to Watch — 2026년 5월 18일
The KOSPI index surged toward the 8,000 mark this week, driven by heavy buying in large-cap semiconductor stocks. We’re seeing a clear pivot by foreign investors from semiconductors into robotics and physical AI, setting the stage for a selective market rally centered on chips, robots, and defense in the coming week.
Top 10 Market Sectors and Stocks to Watch — May 18, 2026
Key Weekly Sectors
- AI Semiconductors: Strong inflows into Samsung Electronics and SK Hynix pushed the KOSPI past the 7,900 level, bringing it to the doorstep of 8,000. The market remains heavily skewed toward large-cap tech, with capital concentrating almost entirely on the AI value chain.
- Robotics & Physical AI: Foreign investors have been rotating out of semiconductor giants and aggressively moving into the robotics and physical AI sectors, notably Hyundai Motor, Doosan Robotics, and Rainbow Robotics. This is a significant shift from the semiconductor-exclusive focus seen through April.
- Defense, Space, and Second-Half Earnings Momentum: Companies with strong earnings outlooks for the second half of 2026—such as Hanwha Aerospace, SK Eternix, JYP Ent., SK Networks, HD Hyundai Construction Equipment, Classys, and L&C Bio—are in the spotlight. Stock selection based on fundamental performance will be key next week.
Top 10 Promising Stocks for Next Week

Macro Environment and Strategy
KOSPI Rally Background: On Monday, May 11, the KOSPI closed at 7,822.24 (+4.32%), a robust rebound. Conversely, the KOSDAQ finished flat at 1,207.34 (-0.03%), highlighting the market's extreme focus on large-cap stocks.
The KOSPI nearly hit 8,000 this week, triggering a sidecar, and marked a milestone as SK Hynix surpassed Micron in market capitalization. Following Goldman Sachs, JP Morgan has projected the KOSPI could hit 10,000, while Hyundai Motor Securities suggests 12,000 is possible.
Flow of Funds: Foreign investors continue to sell heavily on the KOSPI, while individual investors are absorbing the supply, driving the index higher. Institutional sentiment remains inconsistent. The KOSDAQ and small-to-mid-cap stocks remain neglected as liquidity funnels into the AI value chain and semiconductor giants.
Macro Risks: Next week’s U.S. CPI release and earnings reports are key variables, alongside potential geopolitical instability in the Middle East and rising oil prices. The University of Michigan's Consumer Sentiment Index came in at 48.2, lower than expected, fueling concerns about cooling consumption.
Strategy for Next Week:
- Monitor for continued gains in AI value chain leaders (Samsung Electronics, SK Hynix) despite the extreme concentration.
- Track the sustainability of the foreign buying momentum in robotics and physical AI.
- Maintain a selective approach to the KOSDAQ and small-cap stocks, as the number of rising stocks is narrowing.
- Pay close attention to potential interest rate path adjustments based on U.S. CPI results.
