South Korean defense companies experienced a dramatic reversal in fortunes as their shares plunged in 2024 after a two-year rally driven by global rearmament following Russia's invasion of Ukraine [1]. The combined market value of the top four Korean defense companies—Hanwha Aerospace, LIG D&A, Hyundai Rotem, and Korea Aerospace—collapsed to approximately 62 trillion won ($46.18 billion) as of end-October from their 52-week peak of 170 trillion won [1]. These companies had previously benefited from competitive pricing and rapid delivery of traditional weapons systems including tanks, artillery, and missile systems [1].
The sharp sell-off reflects a fundamental shift in modern warfare dynamics that threatens South Korea's traditional defense export strengths. The war in Ukraine has demonstrated how relatively inexpensive drones can threaten expensive military equipment, with drone strikes from Iran depleting costly air defense missile stocks of the U.S. and its Gulf allies [1]. Analysts note that procurement priorities are evolving toward drones, counter-drone systems, and air defense capabilities, areas where Chinese competitors dominate pricing [1]. Peter Kim, senior managing director at KB Securities, stated that "Modern warfare is being fought with less traditional weaponry (tanks, cannons, armored vehicles, etc.), which Koreans are positioned for," while acknowledging that "drones, for example, are dominated by China, pricing out other potential competitors from Europe, the U.S., and Asia" [1].
Beyond the strategic shift, multiple near-term factors have pressured South Korean defense stocks. Financial results have disappointed, with Hanwha Aerospace's third-quarter operating profit falling over 46% year-over-year due to delivery-schedule adjustments and one-off costs, sending its shares down more than 28% for the year [1]. Additional headwinds include a stronger won currency, delayed export orders, and fund flows shifting toward the semiconductor sector [1]. Analysts also note that governments have moved slower than expected to convert defense spending pledges into approved budgets and actual orders [1].
CONCLUSION
South Korean defense stocks face a structural challenge as modern warfare increasingly favors drones and counter-drone systems over traditional tanks and artillery—areas where Chinese competitors dominate. Combined with disappointing earnings, currency headwinds, and slower-than-expected government procurement, the sector's two-year rally has decisively reversed, with the top four defense companies losing approximately 63% of their combined market value from peak levels.
