We empirically test the prediction of Pastor, Stambaugh, and Taylor 2020 that green firms can outperform brown firms when climate change concerns strengthen unexpectedly for S&P 500 companies over the period January 2010 - June 2018. To capture unexpected increases in climate change concerns, we...

In the Web Appendix to the paper by Ardia et al. (2017), we provide additional results regarding the implementation and the performance when the PRCC is computed with downside-risk measures. We further test the sensitivity to the value of the bound on the tracking error constraint and discuss...

The Margrabe Best-of-two (MBo2) strategy is a rule-based dynamic investment solution for the two-asset allocation problem. Its typical implementation involves yearly rebalancing the portfolio weights to 50-50 between a high-risk and low-risk asset. It uses intra-year weight adjustments to chase...

The tone of a firm's financial disclosure is increasingly used as a variable in panel data regressions to predict future performance and explain investors' reaction at earnings announcement. We investigate whether tone is informative, and argue that the informativeness of tone increases with the...

In a risk-based portfolio, there is no explicit control for the performance per unit of risk taken. We propose a framework to evaluate the balance between risk and performance at both the portfolio and component level, and to tilt the risk-based portfolio weights towards a state in which the...

This paper evidences the strategic positioning of positive and negative words within a CEO letter as a subtle form of impression management. We find that managers tend to present information in such an order that the reader of the CEO letter has a more positive perception of the underlying...

The Gaussian quasi-maximum likelihood estimator of Multivariate GARCH models is shown to be very sensitive to outliers in the data. A class of robust M-estimators for MGARCH models is developed. To increase the robustness of the estimators, the use of volatility models with the property of...

The R package DEoptim implements the differential evolution algorithm. This algorithm is an evolutionary technique similar to genetic algorithms that is useful for the solution of global optimization problems. In this note we provide an introduction to the package and demonstrate its utility for...
