Performance attribution tear sheet
Finisdom’s tear sheet turns a portfolio into a one-page institutional read: where your return actually came from, how much active risk you’re taking, and which positions and factors are driving it.
What it does
- Brinson attribution — allocation, selection, and interaction effects
- Active return and tracking error versus any benchmark
- Information ratio — active return per unit of active risk
- Factor-risk exposures across value, momentum, and quality
- Marginal contribution to risk (MCTR) per position
- One-page tear sheet you can hand to a client or committee
How it works
Load a portfolio
Point the tear sheet at any saved portfolio or client book and choose the benchmark to measure against.
Decompose the return
The engine splits active return into allocation, selection, and interaction, then maps factor exposures and MCTR.
Read the risk story
See tracking error, information ratio, and which positions and factors are really driving the active bet.
Frequently asked
What is performance attribution?
Performance attribution explains why a portfolio beat or lagged its benchmark by splitting the active return into components — typically allocation (were you in the right areas?), selection (did you pick the right names within them?), and their interaction. It turns a single return number into a story you can act on.
What is Brinson attribution?
Brinson attribution is the classic framework that decomposes active return into allocation, selection, and interaction effects by comparing your weights and returns to the benchmark’s, segment by segment. Finisdom’s tear sheet reports all three.
What is marginal contribution to risk (MCTR)?
MCTR measures how much each position adds to total portfolio risk at the margin — accounting for correlations, not just standalone volatility. It shows where your risk is really concentrated, which is often not where your capital is.
What are tracking error and information ratio?
Tracking error is the volatility of your return relative to the benchmark — how far you stray from it. Information ratio is your active return divided by that tracking error: reward per unit of active risk taken, the key measure of skill for an active mandate.
Is the tear sheet free?
The performance-attribution tear sheet is part of the Finisdom cockpit, available to members. The Learn section explains attribution and factor risk in plain English for free.
