Abstract

This article investigates empirically whether or not there are benefits from international portfolio diversification between financial markets of the US and China. In addition to the seminal approach of Markowitz (1952) that yields the optimal budget shares for minimizing the risk, we also make use of the new approach developed by Hatemi-J and El-Khatib (2015) that provides the optimal weights by maximizing the risk adjusted return of the underlying portfolio. In both cases, it is found that the investors can reduce the unsystematic risk of their portfolio by international diversification with respect to these two largest financial markets in the world. The risk adjusted return of the portfolio that combines risk and return is higher compared to the risk adjusted return of the portfolio created by the standard approach. Furthermore, it is found that the highest budget share in the optimal portfolio belongs to the US market regardless of the estimation method. I benefici della diversificazione del portafoglio tra i mercati finanziari di USA e Cina: evidenze empiriche da due metodi alternativi Questo articolo analizza empiricamente se la diversificazione internazionale del portafoglio tra i mercati finanziari di USA e Cina porta a dei benefici. Oltre all’approccio miliare di Markowitz (1952) che fornisce le quote ottimali del portafoglio che minimizzano il rischio, utilizziamo anche il nuovo modello sviluppato da Hatemi-J e El-Khatib (2015) che calcola i pesi ottimali massimizzando il rendimento, corretto per il rischio, del portafoglio considerato. In entrambi i casi si è riscontrato che gli investitori possono ridurre il rischio non-sistematico del portafoglio tramite la diversificazione internazionale in riferimento ai due maggiori mercati finanziari mondiali. Il rendimento risk-adjusted del portafoglio che combina il rischio e il rendimento è più alto di quello del portafoglio creato tramite l’approccio standard. Inoltre, viene evidenziato che le maggiori quote nel portafoglio ottimale appartengono al mercato americano indipendentemente dal metodo usato.
