Diversificação internacional de investimentos com a utilização de Exchange-Traded Fund e Purchasing Managers' Index

Abstract

The objective of this research is to propose for high income Brazilian investors a model of dynamic allocation with international diversification that uses ETFs and the PMI manufacturing index. ETFs were selected from twelve countries, including the ETF equities in Brazil, EWZ. The portfolios were created with and without the EWZ and two procedures were adopted to weight the assets: (1) maximization of the Sharpe ratio and (2) allocation based on the proportion of GDP. An alternative method of selection of assets was presented, using the PMI manufacturing index as a decision filter for the allocation of the resources. The PMI is usually published on the first business day of each month, is researched in the major countries and is one of the first, if not the first, leading indicator of the economic cycle. When the PMI signaled economic growth, the portfolio consisted of a higher proportion of equities. To evaluate the performance of the proposed portfolio, it was compared to other three global portfolios that followed classical allocation strategies, and one of these was considered a benchmark. The proposed portfolio was also compared to a benchmark created exclusively with brazilian assets. The result suggests that the use of PMI as a decision filter in an active and internationally diversified portfolio using only foreign ETFs and weighted according to the techniques of Modern Portfolio Theory presented higher total return and Generalized Sharpe Ratio than the international and brazilian benchmarks. This result suggests that Brazilian and foreign investors and managers who adopt active management of their portfolios should include PMI as one of the indicators to be observed in the allocation strategy
