Key Stocks Today (Recent Session Highlights)

Tech Stocks: Momentum in AI and semiconductor-related stocks continued as the Nasdaq hit a record high on Thursday. The progress in US-Iran peace talks reduced economic uncertainty, creating a favorable environment for growth stocks.
-
Energy-Related Stocks: While the energy sector remained weak due to concerns over profit declines for shale and refining companies, some defensive stocks drew attention for their stable dividend flows.
Top Losers
- Oil-Related Stocks: The entire energy sector faced pressure as both WTI and Brent crude prices declined.
Macro & Economic Indicators

Global Top News (By Market Impact)
US-Iran Truce Extended by 60 Days
- What happened: Reports that the US and Iran agreed to extend the truce by 60 days and continue negotiations positively impacted Thursday's market. This increases the chances of moving toward a peaceful resolution for a conflict that has persisted for over three months.
- Market Implications: Resolving geopolitical risks means easing oil supply concerns and lowering global inflation pressure. This is expected to reduce Korea's energy import costs and lead to a revaluation of energy stocks.
Oil Price Drop Signals Easing Inflation Concerns
- What happened: WTI and Brent crude prices have fallen for consecutive days following progress in peace talks. This reflects expectations for the potential reopening of the Strait of Hormuz and increased production from Iran and the United Arab Emirates.
- Market Implications: Oil price stabilization is favorable for curbing global inflation and lowers the probability of a rate hike by the US Federal Reserve. This is positive for Korean exporters and energy-importing firms.
Nasdaq and S&P 500 Reach Record Highs
- What happened: US markets signaled strong growth by reaching all-time highs on Thursday. Momentum in tech and growth stocks remains strong.
- Market Implications: The strength of the US market indicates improved global investor sentiment, with a high probability of capital inflows into emerging Asian markets. This has a positive impact on the Korean KOSPI and KOSDAQ.
Oil Prices and Bond Yields Under Downward Pressure
- What happened: Falling oil prices are exerting downward pressure on the 10-year US Treasury yield, leading to a reallocation of assets between bonds and stocks.
- Market Implications: A lower real interest rate environment is favorable for tech and growth stocks while reducing the relative attractiveness of high-dividend defensive stocks. The Korean bond market is also expected to be affected.
Korea Market Checkpoints
The US-Iran truce extension and falling oil prices provide a double positive signal for the Korean market. First, an improvement in the trade balance is expected due to reduced energy import costs. Second, the potential for an interest rate hike by the Bank of Korea is likely to ease due to reduced global inflation concerns. The KOSPI is expected to continue its upward momentum, supported by record highs in the US and positive risk-on sentiment. Semiconductor and IT exporters, along with energy and chemical stocks, are expected to benefit, while oil price stabilization will support the earnings of Korea's major energy importers.
Watch List
- US-Iran Negotiation Progress: Check for further news on peace talks and the timing of the reopening of the Strait of Hormuz.
- Oil Price Volatility: Keep an eye on whether WTI and Brent crude stabilize within the $80-$85 range.
- US Tech Momentum: Monitor the sustainability of Nasdaq’s record highs and potential profit-taking pressure.
- KRW/USD Exchange Rate: Potential for a stronger Won following the downward trend in long-term US interest rates.
- Risk Factors: Unexpected recurrence of Middle East conflicts or a resurgence of global supply instability.
Investor Action Items
-
Morning Session Response: Positive sentiment from US record highs is likely to carry over when the Korean market opens. Keep an eye on whether the KOSPI breaks above the 3,200 mark and the trend of individual tech stock trades.
-
Sectors to Check: Semiconductors and secondary batteries (Samsung Electronics, SK Hynix, LG Energy Solution) and energy-related stocks (oil refining/chemicals). Refining companies expecting improved margins due to oil stabilization are also worth noting.
-
Risk Management: Since the uncertainty surrounding the US-Iran negotiations has not been completely removed, be prepared to respond quickly to news regarding geopolitical risks. Pay attention to the volatility index (VIX) and short-term volatility in oil futures.
