Today's Key Market Issues

1. U.S. Treasury yield surge cools and Wall Street rebounds U.S. stock markets closed higher on September 2 (local time) as Treasury yields took a breather after surging to multi-year highs.

2. Middle East geopolitical risks and rising oil prices Military tensions between the U.S. and Iran have heightened, triggering a spike in crude oil prices due to conflicts near the Strait of Hormuz. This has fueled concerns over global inflation and driven up bond yields worldwide.

3. Domestic market's 'weak start, strong finish' recovery On September 1, the KOSPI dropped to 6,732.47 during intraday trading but erased all losses to close up 0.23% at 6,835.80. This recovery was largely driven by large-cap semiconductor stocks like SK Hynix.

Hot Themes and Notable Stocks Analysis

1. Large-cap semiconductor stocks (SK Hynix, Samsung Electronics) Semiconductor heavyweights that traded weakly during the session on September 1 rebounded strongly as buying pressure poured in late in the day. SK Hynix successfully turned positive during the session, and Samsung Electronics heavily trimmed its losses, playing a crucial role in defending the index.

2. Energy and defense themes (Indirect impact) Crude oil prices surged following news of new airstrikes between the U.S. and Iran. As geopolitical instability near the Strait of Hormuz persists, volatility has expanded for related energy and defense theme stocks.

3. Secondary battery sector The secondary battery sector is drawing attention as diagnoses suggest the down-cycle for product prices (P) and shipment volumes (Q) is nearing its end. In particular, a surge in global energy storage system (ESS) demand is expected to be the core driving force for a future cycle transition.

4. Market trends by major stock Individual stocks are seeing mixed fortunes amid recent market volatility. Notably, some stocks like Hanul Semiconductor (-8.61%) recorded steep declines, while Voronoi (+2.11%) showed relative strength.

Macro Context

1. Global macro uncertainty and rate outlook Following the Federal Reserve's rate hike in August, the era of a 3.00% global benchmark interest rate has returned. Consequently, the September market is likely to reorganize around stocks backed by corporate earnings rather than macroeconomic indicators.

2. Global stock indices status (As of September 1 close) Major indices saw synchronized weakness in the wake of the U.S. stock market drop. The Dow Jones Industrial Average fell 418.31 points (0.79%) to 52,767, the S&P 500 dropped 54.56 points (0.71%) to 7,631, and the Nasdaq Composite plunged 271.12 points (1.03%) to 26,099.

3. Potential for KOSPI to break 7,000 Experts note that despite short-term corrections, the mid-to-long-term upward trend of the KOSPI remains valid. Even amid geopolitical conflicts, the global economy is showing stronger-than-expected resilience, acting as a factor supporting the downside rigidity of the domestic stock market.
