Rob Oliver, CEO of Aura ETFs, discusses the launch of the Aura National Security ETF (DUTY) and how rising geopolitical tensions and expanding defense budgets are reshaping military investment. He explains how the fund balances legacy defense names with high‑growth software and cybersecurity leaders, while also addressing the role of commodities like copper and the impact of AI on ETF operations. The conversation expands to broader portfolio positioning as markets move away from traditional cap‑weighted exposure.
