Carteiras de fundos de pensão otimizadas com investimentos em commodities

Abstract

Brazilian pension funds have allocated 90% of their investments in fixed income and equity. The insertion of alternative investments, such as commodities, can improve the risk / return relationship since it carries zero correlation in comparison with the others. To verify if this new category can be considered as investment in a portfolio with the best risk / return ratio, the Sharpe Ratio was used to compare optimal portfolios that used commodities with others that did not use it. As a robustness test, we applied Ledoit and Wolf (2008), which compares two Sharpe Ratios in non-normal time series. The period considered is 2009 to 2017, we also observed periods of three years. The results showed that fixed income maintains high returns with low volatility and the portfolios resorts it, equities was not relevant for any period analyzed and investments in commodities were considered in the period of high interest of the economy. The Sharpe Ratio of that period was statistically higher than the traditional portfolio.
