[R&E] KOSPI Surpasses 5,550 Mark Clashing with Middle East Oil Shock, Differentiated Market Driven by 'Earnings Visibility'

[R&E: Research & Epoch]

This is News Epoch's signature report that projects a new era of investment through an integrated analysis of global financial data and domestic securities firm research.

Global Market Brief

The New York stock market showed a mixed performance the previous day due to the overlapping burdens of skyrocketing energy prices caused by the spread of geopolitical risks and rising Treasury yields. The S&P 500 index closed at 6,556.37, down 24.63 points (-0.37%) from the previous day, while the tech-heavy NASDAQ fell 184.87 points (-0.84%) to record 21,761.89. The Dow Jones Industrial Average also closed down -0.18% at 46,124.06.

The center of the market narrative was supply anxiety originating from the Middle East. As reports of Pentagon troop deployments intertwined with Iran's selective passage strategy in the Strait of Hormuz, WTI crude oil prices exceeded the $88 per barrel mark, and Brent crude recorded $104.49, stimulating concerns about energy inflation. This macro environment was immediately reflected in the bond market, with the 10-year US Treasury yield recording 4.36% and the 2-year yield also rising to 3.8887%, suppressing expectations of an easing in monetary tightening. However, the Philadelphia Semiconductor Index rose +1.3%, proving its resilience toward industry recovery even in a declining market.

Domestic Market Overview

The domestic stock market the previous day stood out with strong earnings momentum and supply-demand concentration that overwhelmed the uncertainties of the global macroeconomy. KOSPI closed at 5,553.92, surging by a massive 148.24 points (+2.74%) compared to the previous trading day, confirming support near its historical high. KOSDAQ also showed accompanying strength, rising 2.24% to record 1,121.44.

Behind this day's rise lies confidence in the earnings growth of listed companies in 2026. Analyses indicating that the estimated annual operating profit for KOSPI will reach 638 trillion won, an increase of more than 100% year-on-year, secured the market's downward rigidity. Despite the high exchange rate phase where the won-dollar exchange rate fluctuates between 1,494.13 won and 1,500 won, the fact that the 12-month forward price-to-earnings ratio remains at the 9 times level acted as a valuation attraction. In particular, it is analyzed that net buying by foreigners and institutions flowed in as the supply chain value of Korean manufacturing was re-evaluated amidst US-China conflicts and Middle East disputes.

Key Industry Issues and Insights

In the semiconductor sector, differentiated trends by stock were distinctly evident. While global leading stocks such as Nvidia (NASDAQ: NVDA) and Applied Materials (NASDAQ: AMAT) showed a solid flow, Arm (NASDAQ: ARM) in particular saw its stock price surge by 6% on news of a new CPU launch and securing Meta (NASDAQ: META) as an early customer. On the other hand, Micron (NASDAQ: MU) fell by -4.4% despite profitability improvements, recording weakness for four consecutive trading days and sparking controversy over a short-term peak for memory semiconductors. Among domestic companies, PSK proved its technological prowess as its target price was upgraded to 105,000 won along with a forecast that its operating profit in 2026 will reach 132.7 billion won, a 50% increase year-on-year.

The secondary battery sector was the core engine of the domestic stock market's surge on this day. Led by L&F soaring 11.5%, large-cap stocks such as LG Energy Solution, Ecopro, and Samsung SDI simultaneously recorded explosive upward trends. This is the result of expectations for an earnings turnaround after overcoming the chasm being pre-reflected, going beyond a simple technical rebound. In particular, the fact that these stocks were massively included in the newly listed PLUS K-Manufacturing Core Companies Active ETF expanded the supply-demand inflow channel, which also served as a catalyst for the stock price increase.

The automobile and IT parts sectors also solidified an upward trend based on earnings. LG Innotek is observed to record a first-quarter operating profit of 200.4 billion won, a sharp 60.2% increase year-on-year, and its fair value was revised upward to 360,000 won. Samsung Electro-Mechanics also recorded first-quarter sales of 3.0411 trillion won, with its target price soaring to 550,000 won, proving a fundamental improvement centered on high value-added products. In the finished vehicle sector, Kia was presented with a target price of 185,000 won, being recognized for its profitability defense capabilities.

Energy and supply chain risks increased the volatility of the shipping and defense sectors. In the case of Korea Line Corporation, negative forecasts emerged that its operating profit in 2025 would decrease by 37% year-on-year, but its low price-to-book ratio at the 0.3 times level and 350 billion won in cashable assets supported the downside. In the defense field, SNT Motive was spotted accelerating its business diversification by successively acquiring stakes in robot and automation companies.

Market Signals

• KOSPI Earnings Strength: The estimated annual operating profit for KOSPI in 2026 is 638 trillion won, highly likely to grow by over 100% year-on-year, which is the core driver to break away from the current undervaluation phase at the 9 times 12-month forward price-to-earnings ratio level.

• Explosive Supply and Demand for Secondary Batteries: The double-digit fluctuation rates in the secondary battery sector, centered around L&F (+11.5%) and LG Energy Solution (+10.3%), suggest that the industry narrative has shifted from concern to confidence.

• Return of Energy Inflation: In the aftermath of Middle East risks, Brent crude surpassed $104.49 per barrel and WTI rose, coexisting with the dual risks of rising domestic energy import costs and margin pressure on manufacturing.

• Breakthrough of Upper Bounds in Interest and Exchange Rates: The macro environment remains unfavorable, as the 10-year US Treasury yield recorded 4.36% and the won-dollar exchange rate threatens the 1,500 won mark, which is expected to act as a burden on high-valuation stocks.

Epoch View: Investment Implications

The current market shows an aspect where external pressures of rising oil prices and high interest rates caused by geopolitical crises clash with the solid fundamentals of Korean manufacturing. The KOSPI settling at the 5,550 mark is a strong signal that corporate earnings growth is overwhelming macro negative factors. In particular, as seen in the collaboration between Arm and Meta, the expansion of artificial intelligence (AI) infrastructure is leading to actual chip demand, and upward revisions of target prices in the domestic semiconductor and electronic parts sectors mean that direct benefits from this global trend have begun.

In a situation where energy price volatility has become extreme, a strategy focusing on sectors equipped with cost pass-through capabilities is effective. Finished vehicle and parts stocks such as Kia and Hyundai Mobis are substituting the high exchange rate environment into an opportunity to strengthen export competitiveness, while Samsung Electro-Mechanics and LG Innotek are defending profitability based on overwhelming market shares in high value-added substrates and optical sectors. As geopolitical uncertainties have not been resolved, portfolio reorganization centered on hardware with secured earnings visibility rather than highly interest-rate sensitive software is the core to enhancing returns. Ultimately, the potential for further upward movement of the KOSPI depends on the possibility of achieving operating profits exceeding 600 trillion won and the continuity of export data supporting it.
