Single-index model, multiple-index model, and portfolio selection. (English) Zbl 1454.91223

Lee, Cheng Few (ed.) et al., Handbook of financial econometrics, mathematics, statistics, and machine learning. Volume 3. Hackensack, NJ: World Scientific. 2757-2799 (2021).
Summary: This chapter offers some simplifying assumptions that reduce the overall number of calculations of Markowitz models through the use of the Sharpe single-index and multiple-index models. Besides single-index model, we also discuss how multiple-index model can be applied to portfolio selection. We have theoretically demonstrated how single-index and multiple-index portfolio selection models can be used to replace Markowitz portfolio selection model. An Excel example of how to apply the single-index model approach is also demonstrated.
