If your clients want answers from today’s headlines, how do you give them clarity that still makes sense 5–10 years from now?
In this episode of The Registered Investment Advisor Podcast, host Seth Greene interviews Nathaniel “Nat” Guild, founder and president of Apex Equity Research LLC, who discusses one of the most overlooked risks in modern portfolio building: hidden concentration risk. Nathaniel also explains why safeguarding against losses, rather than simply pursuing gains, is the real secret to long-term investing success. He further examines how passive strategies and the rapid growth of private and shadow assets are creating hidden structural risks that many advisors and clients fail to see.
Key Takeaways:
→ The most important factor in investing isn’t maximizing returns; it’s avoiding major drawdowns that can permanently impair capital.
→ Seven to ten stocks now dominate major indexes, meaning many “diversified” portfolios may be far more concentrated than advisors realize.
→ The rise of index funds combined with growth in private assets creates distortions that can amplify volatility and reduce true diversification.
→ Diversifying information intake is just as important as diversifying portfolios.
→ Short-term media narratives often distract from meaningful long-term risks.
