DUTY | U.S. Defense ETF
Why Now
- United States is the world’s largest defense spender, at roughly $997 billion, representing 1/3 of global military expenditure¹
- Cybersecurity threats accelerating with damages projected to exceed $10 trillion annually by 2025²
- The U.S. CHIPS and Science Act provides more than $50 billion to strengthen semiconductor supply chains³
These structural trends are reshaping national-security priorities and driving long-term investment in defense, cybersecurity, and strategic technologies
What makes DUTY different
- Focus on modern defense technologies
- Strategic Cybersecurity exposure
- Emphasis on defense-driven revenues
- Commitment to veteran support
Modern Defense Infrastructure
Global security priorities are shifting toward advanced defense systems.
DUTY provides exposure to companies supporting next-generation military systems, drones, space defense, and mission-critical technologies
Defense spending is driven by long-term government priorities rather than economic cycles.
Strategic Cybersecurity Exposure
National security is increasingly digital.
Cyber threats to governments, infrastructure, and financial systems continue to rise. Cybersecurity spending has become structural.
DUTY provides exposure to companies protecting governments and infrastructure through network security, cyber intelligence, and defense-grade software
Cybersecurity is a core pillar of modern defense.
Focused Exposure to Defense Revenues
The Index methodology emphasizes companies with meaningful defense-related revenues while limiting exposure to firms primarily driven by commercial aviation
This approach aims to provide focused exposure to national-security spending trends.
