2. Interest in Battery Stocks After Adjustments
- Battery-related stocks like LG Energy Solution, Samsung SDI, Daejoo Electronic Materials, and Lotte Energy Materials are seen as potential leaders for the second half of 2026, supported by EV market growth and stabilizing lithium prices.
3. Portfolio Diversification via Growth ETFs
- For beginner investors in 2026, building portfolios with thematic ETFs covering AI, semiconductors, and energy is becoming a popular way to mitigate the risks of picking individual stocks.
Investment Risks & Macro Context
1. Volatility in Middle East Geopolitics
- While U.S.-Iran ceasefire talks are ongoing, oil price volatility could spike depending on the outcome. Given Korea’s heavy reliance on crude oil imports (approx. 70% from the Middle East), monitor the energy market closely.
2. Increased Correlation with U.S. Tech
- Korean semiconductor stocks are increasingly tracking the U.S. Nasdaq and the Philadelphia Semiconductor Index (SOX). Keeping a close eye on U.S. economic data and interest rate policies is essential.
3. Inflation Relief from Lower Oil Prices
- While lower oil prices have eased inflationary pressure—acting as a boost for risk assets—it is important to manage currency volatility in the won.
