In this episode of Fox and Cents, Alex and Maya dig into the real limitations of index fund investing — not to scare you away from them, but to make sure you actually understand what you own.
A lot of people hear "buy an index fund, set it and forget it" and assume they're fully covered. But if your S&P 500 fund puts roughly 35–40% of your money into just 10 companies, are you really as diversified as you think? This episode unpacks concentration risk, market-cap weighting, and the quiet difference between owning "the market" and owning a specific bet on part of it — in plain English, with no jargon left unexplained.
If you've ever asked yourself "are index funds actually safe?" or "what's the difference between an S&P 500 fund and a total market fund?" — this episode answers both, and goes a few layers deeper than most content on this topic does.
Alex and Maya also cover the behavioral risk that almost nobody mentions: why the average investor underperforms their own fund, what tracking error means in practice, how to spot a thematic ETF masquerading as broad diversification, and the one question you should honestly answer before your next market correction hits.
