The dynamics of the equal-time cross-correlation matrix of multivariate financial time series is explored by examination of the eigenvalue spectrum over sliding time windows. Empirical results for the S&P 500 and the Dow Jones Euro Stoxx 50 indices reveal that the dynamics of the small...

This paper investigates the hedging effectiveness of a dynamic moving window OLS hedging model, formed using wavelet decomposed time-series. The wavelet transform is applied to calculate the appropriate dynamic minimum-variance hedge ratio for various hedging horizons for a number of assets. The...

In this paper, we explore the impact of investor time-horizon on an optimal downside hedged energy portfolio. Previous studies have shown that minimum-variance hedging effectiveness improves for longer horizons using variance as the performance metric. This paper investigates whether this result...

This paper examines the impact of investor preferences on the optimal futures hedging strategy and associated hedging performance. Explicit risk aversion levels are often overlooked in hedging analysis. Applying a mean-variance hedging objective, the optimal futures hedging ratio is determined...

The cross correlation matrix between equities comprises multiple interactions between traders with varying strategies and time horizons. In this paper, we use the Maximum Overlap Discrete Wavelet Transform to calculate correlation matrices over different timescales and then explore the...

To mitigate potential contagion from future banking crises, the European Commission recently proposed a framework which would provide for the bail-in of bank creditors in the event of failure. In this study, we examine this framework retrospectively in the context of failed European banks during...

To mitigate potential contagion from future banking crises, the European Commission recently proposed a framework which would provide for the $\textit{bail-in}$ of bank creditors in the event of failure. In this study, we examine this framework retrospectively in the context of failed European...

In this paper, we explore the impact of investor time-horizon on an optimal downside hedged energy portfolio. The optimal heating oil hedge ratio is first calculated for a variety of downside risk objective functions at different time-horizons using the wavelet transform. Next, associated...
