- Calculate Aggregate Estimate for Pure Sector Allocation.
- Calculate Sector Weights by Differences in Returns.
- Calculate Aggregate Estimate for Returns.
What is attribution interaction?
The attribution analysis dissects the value added into three components: Interaction captures the value added that is not attributable solely to the asset allocation and stock selection decisions. It is positive when outperformance is overweighted and when underperformance is underweighted.

An interaction effect happens when one explanatory variable interacts with another explanatory variable on a response variable. This is opposed to the “main effect” which is the action of a single independent variable on the dependent variable.
How do you calculate portfolio contribution?
The contribution calculation is done by multiplying each sector’s weight by its return, and then summing the results.
What is portfolio risk attribution?
Risk attribution is a methodology to decompose the total risk of a portfolio into smaller terms. The problem is solved in a way that the smaller decomposed units of the total risk are interpreted as the risk contribution of the corresponding subsets of the portfolio.
