I joined my longtime friend Tom Cock for a special edition of Talking Real Money — a wide-ranging conversation about the evolution of indexing, the proposed changes to the S&P 500, and why investors should understand both the strengths and limitations of traditional index funds. I explain why firms like Dimensional Fund Advisors and Avantis Investors use a more flexible, evidence-based approach than traditional indexing, and how academic research has reshaped portfolio construction over the past several decades.

We also explore lessons from market history, including the importance of understanding major bear markets, determining appropriate risk levels, and building portfolios that align with your personal goals rather than chasing maximum returns. I share insights from the latest Dimensional Matrix Book and explain why I believe studying 100 years of market data helps investors stay disciplined during inevitable downturns.

Finally, I introduce a simple but powerful strategy for helping newborns and young children build substantial retirement wealth through small annual investments that can compound over many decades.
