    Truth in Returns

    Accurate return calculation, benchmark comparison, attribution analysis, and risk-adjusted performance metrics.

    "Comparing your balanced portfolio to the S&P 500 is apples to oranges. Match your benchmark to your risk profile, or the comparison is meaningless."

    "How am I doing?" seems like a simple question, but the answer depends on how you measure. Time-weighted return (TWR) shows investment skill irrespective of cash flows. Money-weighted return (MWR/IRR) shows your actual experience including timing of contributions and withdrawals.

    Beyond returns, attribution analysis decomposes performance into allocation effect (asset class decisions), selection effect (individual security choices), and timing effect (when you moved). This tells you WHY you performed, not just what the number was.

    In this topic, you'll learn to calculate returns correctly, choose appropriate benchmarks, understand what drove your performance, and communicate results clearly.

    Common Pitfalls

    1

    TWR measures investment skill, MWR measures your actual wealth change

    2

    Benchmark selection matters - match risk profile, not just asset class

    3

    Attribution analysis tells you WHY, not just what

    4

    Risk-adjusted returns (Sharpe, Sortino) are more meaningful than raw returns

    5

    Periods matter - monthly, quarterly, annual, since-inception all tell different stories
