Summary

Dr. So Hyeon-cheol draws a historical parallel between the 1980s Korean market rally and today's environment, arguing that AI-fueled trade surpluses and US geopolitical strategy could drive a long-term KOSPI boom. He identifies tactical opportunities in Korean memory semiconductors (technical rebound), safer play in Samsung Electronics, and long-term growth in shipbuilders and defense stocks (LIG Nex1, Hanwha Aerospace, KAI), while highlighting Posco Holdings as a rare earth value play.

  • Historical pattern: 1980s rally fueled by low oil, low rates, weak won; now AI exports drive a similar trade surplus, suggesting KOSPI could aim for 9,000 long-term.
  • DRAM price cycle is slowing, but a technical rebound is likely; Samsung Electronics is safer due to diversified businesses (foundry, handsets).
  • Korean shipbuilders (HD Hyundai Heavy, Hanwha Ocean) are a buying opportunity after missing a Canadian submarine deal, as global naval demand shifts to Korea and SMR-powered ships emerge.
  • Hanwha Aerospace is the core of Korea’s space program, which targets 70 trillion won in industry size and a Korean Starlink for 6G.
  • LIG Nex1 offers world-leading missile defense (96% intercept) and benefits from strong global air defense demand.
  • KAI (Korea Aerospace) is worth monitoring for KF-21 fighter and manned-unmanned composite combat, though valuation is high.
  • Posco Holdings at 0.4x P/B with improving earnings, anti-dumping tariffs, and rare earth development presents a value opportunity.
Ideas

KOSPI could surge to 9,000 points
Korea's current situation mirrors the 1980s, when low oil, low rates, and a weak won generated a massive trade surplus that drove the KOSPI from 200 to 1,000 (a 5x rally). Today, AI semiconductor exports are driving a similar trade surplus, and the US geopolitical realignment favors Korea, setting the stage for a long-term bull market that could take the KOSPI from 2,500 toward 9,000.

Memory stocks ready for technical rebound
Despite the recent sharp correction in memory stocks driven by supply-and-demand issues and a deceleration in DRAM price growth (from +95% QoQ in Q1 to an expected +5-10% in Q4), the downside is largely priced in. A technical rebound is likely in the near term, though upside from here will be more limited than in the first half. Investors should use rallies to adjust weightings.

Samsung is safer diversified semiconductor play
Samsung Electronics is a safer semiconductor play than pure memory companies because it is diversified across foundry, handsets, and memory. This portfolio diversification provides a buffer during memory downturns, and Samsung's foundry business is relatively better positioned than Intel, with its Texas plant providing a geopolitical buffer. Additionally, Samsung recently regained the top spot in smartphones, and a stabilization in DRAM prices would also benefit its handset business.

Korean shipbuilders dip is buying opportunity
Korean shipbuilders have underperformed Japanese peers and recently dipped after losing a Canadian submarine order to Germany, but this pullback is a buying opportunity. The lost deal actually enhanced the reputation of Korean submarines (Dosan Ahn Chang-ho class), and Germany's ThyssenKrupp lacks additional production capacity, meaning future orders will shift to Korea. Additionally, HD Hyundai Heavy Industries is developing SMR-powered ships with TerraPower, and the entire sector is being transformed by a shift toward naval shipbuilding, providing long-term growth.

LIG Nex1 benefits from missile defense demand
LIG Nex1 is a key beneficiary of Korea's world-class missile defense system, which includes the Cheongung-II (96% intercept rate) and L-SAM. The company's semiconductor technology heritage (spun off from LG Innotek) gives it an edge in guidance and precision. Strong global demand for air defense, especially from Middle Eastern nations, provides a long runway of orders.

Hanwha Aerospace leads Korea's space program
Hanwha Aerospace is the core company for Korea's space ambitions. The government plans to grow the space industry from 11 trillion won to 70 trillion won and develop a Korean Starlink for 6G communications. Hanwha Aerospace manufactures the launch vehicles (rockets) needed to deploy satellites, making it indispensable to this national project.

KAI worth watching for KF-21 exports
Korea Aerospace Industries (KAI) is worth monitoring because of the KF-21 fighter jet program and the move toward manned-unmanned composite combat systems. However, valuations are already elevated, making shipbuilders a more comfortable choice from a valuation perspective.

Posco Holdings value play with rare earths
Posco Holdings is a compelling value play trading at just 0.4x P/B with improving earnings thanks to anti-dumping tariffs on Chinese steel. Additionally, the company is shifting focus to rare earth development through Posco International, and its battery materials business is turning profitable. This diversification into resources and rare earths makes it a more attractive long-term story than a pure steel play.
