Contributive Alpha as the Basis for Investment Performance Attribution
$25
If the foundations of investment performance attribution models are examined, it shows that traditional attribution analysis using arithmetic or geometric excess return does not reveal how a portfolio’s return was achieved. It is argued that contribution alpha is an alternative measure for the return from active management that appears to be a more compelling basis for investment portfolio attribution models.
