[R&E] Collision of Semiconductor and Nuclear Power Fundamentals with Geopolitical Shocks... 'Selective Defense' Strategy in the Era of a 1,500 KRW Exchange Rate

Market Summary: Key Indicators and Trends

Late last week, the New York stock market continued its downward trend for a fourth consecutive week due to overlapping concerns over the spread of an all-out war in the Middle East and upward pressure on interest rates. The S&P 500 (-1.51%) and NASDAQ (-2.01%) broke below their major support level, the 200-day moving average, and the steepening of the yield curve intensified, with the 10-year US Treasury yield soaring to 4.3796% in particular. This suggests that expectations for interest rate cuts within the year have virtually disappeared and fears of recurring inflation have begun to dominate the market. In contrast, on the previous trading day, the domestic stock market closed at KOSPI 5,781.20 (+0.31%) and KOSDAQ 1,162.52 (+1.58%), showing differentiated resilience backed by solid flows in the semiconductor and biotech sectors despite adverse global macroeconomic conditions.

Today's market is expected to start amid the double whammy of the KRW/USD exchange rate (1,504.7 KRW) breaking through 1,500 KRW and a surge in international oil prices. The deterioration of investor sentiment across US tech stocks will act as downward pressure, but a 'compressed stock-picking market' is highly likely, with Samsung Electronics' announcement of large-scale facility investments and nuclear power plant order momentum supporting the downside. As the preference for safe assets strengthens due to the prolongation of geopolitical risks, it is essential to build a defensive position focused on large-cap value stocks with secured earnings visibility.

Key Industry Issues and Insights

The semiconductor industry is demonstrating overwhelming earnings growth, breaking through macroeconomic uncertainties. The decision by Samsung Electronics (KRX: 005930) to execute an investment worth 110 trillion KRW in its P4/P5 plants and the Taylor facility in the US is analyzed as a strong commitment toward securing leadership in AI semiconductors. In particular, memory semiconductor exports in March surged 185% year-on-year, proving the strength of the industry's recovery. SK hynix (KRX: 000660) is also solidifying its dominance in the AI memory market, recording a weekly surge of 10.7% amid the aftereffects of NVIDIA (NASDAQ: NVDA) GTC. However, the 33.32% plunge of Super Micro Computer (NASDAQ: SMCI) in the US market and allegations of AI chip smuggling are variables that will cause short-term volatility in the investor sentiment of related domestic components companies.

The energy and construction sectors are transforming geopolitical crises into opportunities. As mounting tensions in the Middle East threaten to push Dubai crude to $170 per barrel, the inflow of funds into the nuclear power and renewable energy sectors, which are directly linked to energy security, is evident. The fact that SK Oceanplant (KRX: 100090) approached the daily upper limit price benefiting from the 'energy highway' policy, and that Daewoo E&C (KRX: 047040) surged 18.2% in a single day driven by expectations of nuclear power plant orders, shows that the market's interest has shifted to the two pillars of 'low PBR' and 'energy independence.' The automobile sector is also expected to highlight its valuation appeal ahead of the earnings season, as Hyundai Motor (KRX: 005380) and Kia (KRX: 000270) are accelerating structural improvements by significantly expanding their electric vehicle and EREV lineups by 2030.

Market Signals

  • Samsung Electronics' 110 Trillion KRW Investment Gambit: The unprecedented upward revision in facility investment, coupled with the 185% surge in memory semiconductor exports, is a clear signal that will directly lead to long-term benefits for the domestic materials, components, and equipment ecosystem such as TES and VM.

  • Entering the Era of a 1,500 KRW Exchange Rate: The exchange rate hitting 1,504.7 KRW is a factor improving the profitability of export companies, but it acts as a double-edged sword that pressures interest rates due to the outflow of foreign capital and rising import prices.

  • Super Micro Computer (SMCI) Plunges 33.32%: The allegations of AI chip smuggling by executives and employees and the resignation of the board of directors highlight moral hazard and regulatory risks across tech stocks, acting as factors that will exert downward pressure on large tech stocks such as NVIDIA.

Epoch View: Investment Implications

The current market is in a complex crisis phase where the 'three highs' of high inflation, high interest rates, and high exchange rates are combined with geopolitical risks. However, attention should be paid to the polarization phenomenon where the earnings momentum of certain sectors becomes clearer even amid the downward pressure on the index. In the case of semiconductors, despite persistent risks of US-China conflicts and export regulations, the restructuring of the supply chain centered on Samsung Electronics and SK hynix is accelerating, demonstrating strong earnings defensiveness.

Right now, rather than tracking the entire index, a valid strategy is to focus on sectors strictly supported by earnings. Construction companies expecting visible nuclear power plant orders, financial stocks anticipated to directly benefit from corporate value enhancement programs, and the K-beauty and food & beverage sectors expanding their global market shares are alternatives. In particular, it is a time that requires a selective approach utilizing the refining and renewable energy sectors as a means of hedging portfolio risks in preparation for an energy shock originating from the Middle East.
