Review allocation, diversification, fees, overlap, and risk across all investment accounts.

A portfolio is everything you own for investing, not just the account you opened most recently. Analysis helps you see the whole picture.

Start With Allocation

Add up your investments across all accounts and group them by broad category:

  • US stocks
  • International stocks
  • Bonds
  • Cash
  • Real estate or alternatives
  • Concentrated company stock

Compare the total to your target mix. If you do not have a target mix, that is the first decision.

Check For Overlap

Owning five funds does not guarantee diversification. Several funds may hold the same large companies. Overlap can make a portfolio riskier than it looks.

Review Fees

Look for expense ratios, advisory fees, fund transaction fees, and account fees. Fees are not automatically bad, but every fee should have a job.

Review Risk

Ask what would happen if stocks fell sharply, interest rates changed, one employer stock dropped, or you needed cash earlier than planned.

Watch Out

Do not make big changes just because one fund had a bad month. Portfolio analysis is about structure, not chasing recent performance.

The Bottom Line

Good portfolio analysis answers three questions: What do I own? Why do I own it? Is it still aligned with my timeline and risk capacity?
