GDFN focuses on companies within the aerospace and defense sector, investing in pure-play stocks from defense-related activities and prioritizing innovation. Investments center in three key sub-sectors: defense equipment (robotics, drones, military vehicles, space tech, sensor and networking systems, and advanced weaponry), defense technology (AI, IoT, AR/VR, big data analytics, geospatial intelligence, security scanning solutions), and cyber defense firms protecting critical infrastructure. The fund primarily holds between 15 to 100 companies outside the US and Canada, with up to 25% in emerging markets. Security selection combines top-down sector and bottom-up fundamental and valuation analysis to identify attractively valued companies with strong growth prospects. The fund does not hedge currency risk. The fund may engage in security lending. As an actively managed fund, the adviser continuously monitors and adjusts the portfolio based on market and company developments.
