Episode notes

You’ve been told to “just invest in index funds”... and somehow that made you feel more confused, not less.

Like – which one, why, and what am I even looking at??

If you’ve ever opened your 401k, saw words like large cap, emerging markets, growth, value and immediately checked out… this episode is your reset.

In this episode, you’ll learn:

  • Why “just invest in index funds” is incomplete advice — and what’s missing when people say it
  • How the stock market is organized behind the scenes so fund names finally start to make sense
  • The main ways index funds are grouped, including:
    • by location (U.S. vs international vs emerging markets)
    • by company size (large, mid, small cap)
    • by style (growth vs value — and what that actually means for your money)
    • by sector (tech, healthcare, etc.)
  • How to decode your own portfolio just by reading fund names (like “U.S. large cap growth”)
  • Why having more funds doesn’t automatically mean you’re more diversified
