Thereof, what is the difference between contribution and attribution?
“Attribution” is the idea that a change is solely due to your intervention. “Contribution” is the idea that your influence is just one of many factors which contribute to a change.
Factor-based performance attribution is commonly used to explain the sources of realized return of a portfolio. The methodology relies on a factor model of asset returns to decompose a portfolio's return according to a set of factors.
