The multi-index model used here gives a diagonal form of the covariance matrix between stocks. The assumptions for this model is that stocks are linearly related to the group index (industry) and the industry is linearly related to the market index. Multi-index notation is a mathematical notation that simplifies formulas used in multivariable calculus, partial differential equations and the theory of distributions, by generalising the concept of an integer index to an ordered tuple of indices. The single-index model (SIM) is a simple asset pricing model to measure both the risk and the return of a stock. The model has been developed by William Sharpe in 1963 and is commonly used in the finance industry. The Single Index Model (SIM) is an asset pricing model, according to which the returns on a security can be represented as a linear relationship with any economic variable relevant to the security. In case of stocks, this single factor is the market return. The models considered in the analysis consist of a single index model, four multi‐index models, and two constant correlation models. Unlike the previous approach, the proposed algorithm does not require explicit ranking of securities.
In finance, a multi-factor model employs a set of different factors in its computations in order to analyze and explain market phenomena, as well as equilibrium

Dimension reduction can be used as an initial step in statistical modeling. Further specification of model structure is imminent and important when the reduced dimension is still greater than 1. Estimation of a general multi-index model comprises determining the number of linear combinations of predictors (structural dimension) that are related to the response, estimating the loadings of each index vector, selecting the active predictors and estimating the underlying link function.

residual risk. When we have a multi-index model, it is often sensible to assume that residuals are un-correlated. In this case,. In finance, a multi-factor model employs a set of different factors in its computations in order to analyze and explain market phenomena, as well as equilibrium Beyond demonstrating that our approach enables prediction with polyno- mial accuracy, we also include generalizations to iteratively fitted multiple index models, Dimension reduction can be used as an initial step in statistical modeling.

A model of stock returns that decomposes influences on returns into a systematic factor, as measured by the return on the broad market index, and firm specific A multi-factor model is a financial model that employs multiple factors in its calculations to explain market phenomena and/or equilibrium asset prices. The multi-factor model can be used to explain either an individual security or a portfolio of securities. It does so by comparing two or more factors
