[E-Daily Reporter Park Sun-Yeop ] A new exchange-traded fund (ETF) has been launched that concentrates its investments on leading domestic defense industry stocks. Rather than being a thematic product that simply bets on war or geopolitical tensions, this ETF targets the value chain of air defense weapon systems, for which demand is growing amid the global trend toward rearmament. While it primarily holds shares in leading defense companies, a key feature is its increased weighting of companies involved in air defense systems—a sector whose importance has grown due to expanding threats from drones and missiles.
According to the Korea Exchange on the 11th, Korea Investment Trust Management newly listed the “ACE K-Defense TOP5+” ETF on the Main Board on the 7th. This product is a passive ETF that invests in 10 defense-related companies listed on the domestic stock market. Its benchmark index is the “KRX K-AI Defense TOP5+ Index,” and the total expense ratio is 0.45% per annum. Investors can allocate up to 100% of their assets to this ETF in individual retirement accounts and up to 70% in corporate retirement pension accounts.

The portfolio features a concentrated structure that emphasizes leading defense stocks. Rather than simply selecting stocks based on market capitalization, the weightings are determined by equally weighting an “AI Defense” keyword score and liquidity-adjusted market capitalization. Based on this criteria, 80% of the total portfolio is allocated to the top five stocks, and the remaining five stocks are included within the 20% allocation. However, to prevent concentration in specific stocks, the weight of any single stock is capped at 20%.
As of the listing date, the top five stocks were LIG Nex1 Co., Ltd.(079550), HYUNDAI ROTEM(064350), HANWHA AEROSPACE(012450), KOREA AEROSPACE INDUSTRIES(047810), and HANWHA SYSTEMS(272210). In addition, companies related to defense, aerospace, telecommunications, and electronic equipment—such as Satrec Initiative Co., Ltd.(099320), RFHIC CORPORATION(218410), i3system, Ind.(214430), INTELLIAN TECHNOLOGIES Inc.(189300), and Life Semantics Corp.(347700) —are also included. Rebalancing takes place four times a year in January, April, July, and October.
The key investment thesis behind this ETF is that demand for defense products is expanding beyond one-off war-related themes to become a structurally growing industry. Amid deglobalization and the formation of security blocs, demand for military buildup is growing, particularly in Europe and the Middle East, and the trend toward replenishing weapons stockpiles and strengthening self-defense capabilities is likely to continue even after the war ends.
Kim Jin-young, an analyst at KIWOOM Securities, stated, “As U.S. security intervention decreases amid deglobalization, military buildup is gaining momentum, particularly in Europe and the Middle East.” He added, “Even after the war ends, demand will persist for replenishing depleted weapon stocks, strengthening self-defense capabilities to reduce dependence on the U.S., and establishing permanent defense systems to prepare for potential renewed conflicts.”
In particular, this report focuses on air defense weapon systems. As threats from drones, ballistic missiles, and long-range strike capabilities grow, the importance of defense systems has increased. Against this backdrop, South Korean air defense systems are gaining attention as alternatives to existing U.S. and European weapons, thanks to their price competitiveness, timely supply capabilities, and interoperability with U.S. weapon systems.
Leading companies in this sector include HANWHA AEROSPACE, LIG Defense&Aerospace, and HANWHA SYSTEMS. HANWHA AEROSPACE is regarded as a comprehensive defense platform company with a full range of capabilities, from launchers and vehicles to interceptors. LIG Defense&Aerospace is cited as a direct beneficiary of the expanding exports of the Cheon-gung II, thanks to its capabilities in guided missiles and system integration. HANWHA SYSTEMS serves as the “eyes and brain” of air defense networks, providing radars, sensors, and engagement control systems.
However, given the nature of defense ETFs, investors must account for volatility driven by geopolitical news and order trends. Since these ETFs have a high concentration in specific sectors and a small number of large-cap stocks, individual companies’ earnings, delays in export contracts, and valuation pressures can significantly impact returns. While defense stocks offer strong long-term growth prospects, they can be highly sensitive in the short term to factors such as government budgets, export approvals, delivery schedules, and exchange rates.
