This study presents a model to select the optimal hedge ratios of a portfolio composed of an arbitrary number of commodities. In particular, returns dependency and heterogeneous investment horizons are accounted for by copulas and wavelets, respectively. A portfolio of London Metal Exchange...

In financial time series, persistence or inertia is a feature usually observable in absolute returns, i.e., a proxy for volatility. Moreover, asset return series should be essentially unpredictable according to the efficiency market hypothesis (EMH) in its weak form. Surprisingly, recent...

Spatial dependency has been studied in several research areas, such as environmental criminology, economic geography, environmental sciences, and urban economics. However, it has essentially been overlooked in other subfields of economics and in the field of finance as a whole. A key element at...

This paper analyzes the profitability of Chile's retirement multifund system—funds A, B, C, D, and E—since its launch in 2002. The analysis shows that the rates of return on the funds are highly correlated across pension fund administrators (PFAs) and that risk-adjusted returns on these...

Extreme value theory (EVT) focuses on modeling the tail behavior of a loss distribution using only extreme values rather than the whole data set. For a sample of 10 countries with dirty/free float regimes, we investigate whether paired currencies exhibit a pattern of asymptotic dependence. That...

The existence of feedback effects between volatility and institutional investor holdings has been extensively studied for the United States. This article contributes to the literature by investigating this issue for Pension Fund Administrators (PFAs) in Chile. To this end, data on PFAs' holdings...

We apply linear and non-linear Granger causality tests to four U.S. price indices and 31 commodity series, which expand a 54-year period (January 1957–December 2011). We find evidence of linear Granger causality mostly from individual commodities to price indices. The latter, however, seem to...

Copula modeling has become an increasingly popular tool in finance to model assets returns dependency. In essence, copulas enable us to extract the dependence structure from the joint distribution function of a set of random variables and, at the same time, to isolate such dependence structure...

In this article, we study the behavior of the stock prices of a subset of eight U.S. industries from the late 1800's to the Great Depression. In particular, we focus on the potential presence of volatility shifts, the persistence of volatility, and on the degree of co-movement of stock returns...

We analyze the implications for portfolio management of accounting for conditional heteroskedasticity and sudden changes in volatility, based on a sample of weekly data of the Dow Jones Country Titans, the CBT-municipal bond, spot and futures prices of commodities for the period 1992–2005. To...
