Investment Podcast #36 - Rethinking Genuine Diversification

As portfolios become increasingly concentrated beneath the surface, host James Whelan is joined by Eric Marais (Orbis Investments) to challenge what genuine diversification really means. They unpack how passive indices and many active funds are heavily exposed to US mega-cap, tech-driven growth themes, creating hidden risks if leadership shifts. Drawing on history and current valuation extremes, the discussion highlights opportunities beyond the obvious—including mid-caps, healthcare, and international markets—while stressing diversification across style, geography, and currency. With a focus on preparation over prediction, this episode helps advisers build portfolios resilient to a wider range of outcomes.
