Diversification, For Real

Everyone says “diversify.” This module names the two enemies it actually fights, concentration and correlation, shows how the protection is really built, tells you honestly what it costs and when it disappoints, and ends with the job each holding does in your own plan.

By the end of this module, you’ll be able to:

  • Read a holdings list for shared risks and single-event exposure.
  • Explain the return trade-off when diversification adds bonds or cash.
  • Check what an index fund spreads across before treating it as a complete portfolio.
  • Include your job and home when checking concentration in your finances.
  • Explain why different holdings can still fall together.
  • Explain how regular contributions spread purchases across dates.
