Cumulative Frongello-Equivalent Attribution

I present an arithmetic decomposition of cumulative relative performance into cumulative attribution factors, using geometric relative performance. Somewhat surprisingly, it turns out to be equivalent to the Frongello method for multi-period benchmark-relative attribution based on arithmetic relative performance.

I present an arithmetic decomposition of cumulative relative performance into cumulative attribution factors, using geometric relative performance. Somewhat surprisingly, it turns out to be equivalent to the Frongello method for multi-period benchmark-relative attribution based on arithmetic relative performance.1 However, starting with geometric cumulative relative performance yields a derivation that is easier to understand and produces results that can be used more fully.
