Multi-factor attribution

Definition

Multi-factor attribution is a performance analysis technique that breaks down the returns of an investment portfolio into various contributing factors, allowing investors to understand the sources of returns more clearly. This method evaluates how different factors, such as asset allocation, sector performance, and individual security selection, influence overall portfolio performance. By isolating these effects, multi-factor attribution provides deeper insights into both the strengths and weaknesses of an investment strategy.
