The lessons

  1. 10.1

    Reviewing a real portfolio, week by week

    The weekly series, and the three numbers it keeps coming back to.

  2. 10.2

    Total return vs price return

    Judging a dividend portfolio on price alone flatters the wrong holdings.

  3. 10.3

    What your cost basis is, and why it moves

    Buying in stages, fees, and the corporate action that rewrites it.

  4. 10.4

    Unrealised vs realised gain

    A gain on the screen and a gain in your pocket are taxed very differently.

  5. 10.5

    CAGR vs total return

    Why the smaller number is the honest one.

  6. 10.6

    Time-weighted vs money-weighted return

    One judges the portfolio. The other judges your timing.

  7. 10.7

    What benchmarking against an index proves

    Beating an index over a year proves less than it feels like.

  8. 10.8

    Survivorship bias in every backtest you've seen

    The companies that failed left the index, and left the chart.

  9. 10.9

    Reading your AI portfolio report

    What the report looked at, what it didn't, and what it isn't.

  10. 10.10

    Why two apps show different returns for the same portfolio

    Same holdings, different method, different answer. Neither is broken.
