Abstract: Factor models of security returns decompose the random return on each of a cross-section of assets into pervasive components, affecting almost all assets, and a diversifiable component. We describe four alternative approaches to factor models of asset returns. We also discuss issues related to estimating factor models and testing for the appropriate number of factors.
