Modeling the term structure of interest rate is very important to macroeconomists and financial market practitioners in general. In this paper, we used the Diebold-Li interpretation to the Nelson Siegel model in order to fit and forecast the Brazilian yield curve. The data consisted of daily...

Using sectorial indices of the Brazilian market, we compare the portfolio optimization approach known as risk parity with minimum variance and equally weighted approaches. We apply various estimators for the covariance matrix to each portfolio strategy, since portfolio variance is considered as...

We re-examine the validity of the Expectation Hypothesis (EH) of the term structure for the Brazilian fixed income market, using data from Jan-2000 to Jun-2017. Furthermore, we investigated the out-of-sample predictability of bond excess returns by means of common factors extracted from a...

This study analyzed the effect of foreign portfolio capital flows on stock returns of Brazilian listed firms through a 6-factors APT model, in which an additional risk factor for foreign portfolio capital flows was included. First, in an aggregate analysis, the partial effect of foreign...

This study analyzed the relationship between capital structure, cash holdings and firm value for a sample of publicly traded Brazilian firms, using panel data regressions, employing the fixed-effects estimator. Initially, regressions between capital structure (debt to total capital) and cash...

We assess the extent to which the imposition of a no-arbitrage restriction on the dynamic Nelson-Siegel model helps obtaining more accurate forecasts of the term structure. For that purpose, we provide an empirical application based on a large panel of Brazilian interest rate future contracts...
