Global Market Brief

The New York stock market showed a stark contrast in temperature the previous day. The Dow Jones Industrial Average rose 0.11%, closing slightly higher, but the tech-heavy S&P 500 (NYSE: SPY) index fell 0.39%, and the Nasdaq Composite (NASDAQ: QQQ) dropped 0.73%. In particular, the small-cap-focused Russell 2000 (NYSE: IWM) fell 1.46%, and the Philadelphia Semiconductor Index plunged 4.23%. This is interpreted as a result of high oil prices and a strong dollar exacerbating inflation pressure and dampening investor sentiment toward growth stocks.

Brent crude recorded $112.78 per barrel, and WTI hit $102.88, firmly surpassing the $100 mark. CNBC International analyzed that Brent crude broke through $100 for the first time since 2022, showing a record growth rate. High oil prices are a key inflation driver that increases corporate production costs and weakens consumption power. Meritz Securities suggested the possibility of further increases in US Treasury yields and additional stock market corrections if oil prices continue to rise.

US Treasury yields fell as the preference for safe assets strengthened. The 2-year US Treasury yield recorded 3.8279%, and the 10-year yield was 4.3482%. MarketWatch reported that Middle Eastern oil-producing countries are selling US Treasuries to secure liquidity. The dollar index recorded 100.51 pt, renewing its highest level since May 2025. The strong dollar trend is a factor that increases capital outflow pressure in emerging markets and exacerbates the foreign debt burden. Gold prices also rose to $4,557.5, reflecting market anxiety.

Domestic Market Overview

The domestic stock market plunged, taking a direct hit from the weakness of global tech stocks, high oil prices, and the strong dollar. The KOSPI closed at 5,277.30 (-2.97%) and the KOSDAQ at 1,107.05 (-3.02%), recording drops in the 3% range. Due to the high proportion of semiconductors in the domestic market, the plunge in the Philadelphia Semiconductor Index was a decisive cause of the decline. The won/dollar exchange rate closed at 1,517.9 won, up 6.8 won from the previous day, heightening concerns over import cost burdens and foreign capital outflows.

Domestic government bond yields also showed a downward trend. The 3-year yield recorded 3.542%, and the 10-year yield was 3.895%, revealing a preference for safe assets. Kiwoom Securities presented a KOSPI operating profit forecast of 644 trillion won for 2026, but warned that net profit could be revised down by up to 16% if energy costs continue to rise. In this case, the KOSPI's price-to-earnings ratio (P/E), currently at 7.9 times, is expected to rise, diluting its undervaluation appeal.

Key Industry Issues and Insights

In a high oil price and strong dollar environment, the fates of different industries diverged. While the tech stock correction deepened, some raw material-related sectors succeeded in rebounding.

The semiconductor sector was engulfed in concerns over a global demand slowdown. Micron (NASDAQ: MU) plunged 9.88%, and major companies such as Lam Research (NASDAQ: LRCX) (-5.43%), Intel (NASDAQ: INTC) (-4.50%), and NVIDIA (NASDAQ: NVDA) (-1.40%) all showed weakness. The simultaneous decline of server and cloud-related stocks like Dell Technologies (NYSE: DELL) (-4.16%) and Arista Networks (NYSE: ANET) (-3.84%) proves market anxiety over the pace of AI data center investments being adjusted.

On the other hand, the raw material market showed strength due to supply chain instability. As aluminum prices surged over 4% to renew their highest level since 2022, Sama Aluminium (+9.2%) and Namsun Aluminium (+4.6%) also showed strength in the domestic stock market. Furthermore, as the importance of energy security was highlighted, bargain hunting flowed into offshore wind power-related stocks such as SK Oceanplant (+3.9%) and Unison (+8.1%).

The secondary battery market is mixed. Automakers such as Tesla (NASDAQ: TSLA) (-1.81%) and Ford (NYSE: F) (-1.41%) fell due to concerns over a demand slowdown. However, the domestic battery industry showed a differentiated trend based on technological competitiveness. LG Energy Solution rose 3.7% on news that it innovated stacking speed by introducing a 'double stack' method for prismatic batteries bound for Tesla. L&F also proved its material competitiveness by signing a 1.6 trillion won LFP cathode material supply contract with Samsung SDI.

Market Signals

• Simultaneous Plunge in Domestic Stock Markets: KOSPI and KOSDAQ recorded 5,277.30 and 1,107.05 respectively, threatening psychological support lines.

• Re-entry into the $100 Oil Era: WTI recorded $102.88, deepening global supply chain and inflation risks.

• Semiconductor Downward Pressure Intensifies: Philadelphia Semiconductor Index plunged in the 4% range, triggering a sell-off in domestic large-cap IT stocks.

• Exchange Rate Surpasses 1,517 Won: Widespread wariness of capital outflows from emerging markets due to the entrenchment of the strong dollar trend.

• Surge in Non-ferrous Metal Prices: Major raw material prices such as aluminum returned to 2022 levels, increasing cost burdens.

Epoch View: Investment Implications

The triple hardship of high oil prices, a strong dollar, and a tech stock correction is testing the market's fundamental strength. The domestic stock market, which has high export dependency and a large proportion of semiconductors, is structurally bound to be exposed to external volatility. In particular, it is important to note that rising energy costs are highly likely to damage corporate profit forecasts.

However, even amidst this chaos, opportunities are captured in battery companies that widen their technological gap or raw material-related sectors that benefit from energy transition. In the future, the market is expected to show a more pronounced polarization phenomenon, reorganizing around companies that have secured cost efficiency and technological monopoly. Until macroeconomic uncertainties are resolved, a conservative approach and portfolio reorganization focused on sectors with proven earnings defensive capabilities are essential.
