This study examines volatility spillover dynamics among the S&P 500 index, the US 10-year Treasury yield, the US dollar index futures and the commodity price index. The focus of the study is to analyze effects of Fed's unconventional monetary policy on the US financial markets. We use realized...

We provide a methodology to estimate a global credit risk factor from CDS spreads that can be very useful for risk management. The global risk factor (GRF) reproduces quite well the different episodes that have affected the market over the sample period. It has high correlation with standard...

We consider a nonparametric time series regression model. Our framework allows precise estimation of betas without the usual assumption of betas being piecewise constant. This property makes our framework particularly suitable to study individual stocks. We provide an inference framework for all...

We analyse how the future real economic activity is discounted to the current value of stocks in the US and European markets, and find that the extraordinary threat on future real GDP growth caused by the COVID-19 pandemic was obviously one of the main factors that affected the deep dive in the...

This paper explores the contagious propagation of jumps among international stock market indices by exploiting a rich panel of stock and options data. We propose a multivariate option pricing model designed to allow for, but not superimpose, time and space amplification of jumps in option...

This paper estimates a bivariate HEAVY system including daily and intra-daily volatility equations and its macro-augmented asymmetric power extension. It focuses on economic factors that exacerbate stock market volatility and represent major threats to financial stability. In particular, it...

In this paper we propose a novel approach in analysing the impact of changes in sovereign credit ratings on stock markets. We study the evolution of a segmented form of the stock market index for several crisis-hit countries, including both European and Asian markets. Such evolution is modelled...

The main challenge by the study of systemic risk is the measurement of contagion that enables the impact of external movement in one market on other markets. One of the main tools that has been proposed for this purpose is the risk measure ∆CoVaR of Adrian and Brunnermeier (2011). This study...

This paper analyzes the relationship between debt and the production decision of companies active in the exploration and production of oil and gas in the United States. Over the last couple of years, the development and application of innovative extraction methods, like hydraulic fracturing and...

This paper compares and contrasts factor investing and sector investing, and then seeks a compromise by optimally exploiting the advantages of both styles. Our results show that sector investing is effective for reducing risk through diversification while factor investing is better for capturing...
