This study analyzes portfolio allocation through the linear multifactor model, used in Asset Pricing Theory (APT), linked to the allocation method of Risk Budgeting. The multifactor model is used to try to explain the returns of securities within the market through their exposures to various kinds of risk factors. For this analysis, the factors used were those provided by the Fama & French website, in addition to the factor concerning market risk the others are SMB , HML, RMW and CMA. The study is based on a set of portfolios consisting of equities from the NYSE, AMEX and NASDAQ stock exchanges therefore with special focus on the U.S. market. Finally after estimating the model the contributions to the total risk by the individual factors are calculated and used in the risk budgeting method by assigning risk budgets to the factors, which will affect the respective weights of the portfolios obtaining a point of optimum.
Questo studio analizza l'allocazione di portafoglio attraverso il modello multifattoriale lineare, utilizzato nell'Asset Pricing Theory (APT), collegato al metodo di allocazione del Risk Budgeting. Il modello multifattoriale viene utilizzato per cercare di spiegare i rendimenti dei titoli all’interno del mercato attraverso le loro esposizioni a dei fattori di rischio di vario genere. Per questa analisi, i fattori utilizzati sono stati quelli forniti dal sito di Fama & French, oltre al fattore riguardante il rischio di mercato gli altri sono SMB , HML, RMW e CMA. Lo studio si basa su un insieme di portafogli composti da titoli azionari provenienti alle borse NYSE, AMEX e NASDAQ quindi con particolare focus al mercato americano. Infine dopo aver stimato il modello vengono calcolate le contribuzioni al rischio totale da parte dei singoli fattori e utilizzate nel metodo del risk budgeting assegnando dei budget di rischio ai fattori, che influiranno sui rispettivi pesi dei portafogli ottenendo una punto di ottimo.

Abstract
This study analyzes portfolio allocation through the linear multifactor model, used in Asset Pricing Theory (APT), linked to the allocation method of Risk Budgeting. The multifactor model is used to try to explain the returns of securities within the market through their exposures to various kinds of risk factors. For this analysis, the factors used were those provided by the Fama & French website, in addition to the factor concerning market risk the others are SMB , HML, RMW and CMA. The study is based on a set of portfolios consisting of equities from the NYSE, AMEX and NASDAQ stock exchanges therefore with special focus on the U.S. market. Finally after estimating the model the contributions to the total risk by the individual factors are calculated and used in the risk budgeting method by assigning risk budgets to the factors, which will affect the respective weights of the portfolios obtaining a point of optimum.File | Dimensione | Formato | |
