Trade execution is concerned with the actual mechanics of buying or selling the desired amount of a financial instrument. Investors wishing to execute large orders face a tradeoff between market impact and opportunity cost. ...
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 ...
This paper investigates the effects of early stopping as a method to counteract overfitting in evolutionary data modelling using Genetic Programming. Early stopping has been proposed as a method to avoid model
overtraining, ...

Decision tree learning is one of the most widely used and practical methods for inductive inference. We present a novel method that increases the generalisation of genetically-induced classification trees,
which employ ...
A key issue in the estimation of energy hedges is the hedgers’ attitude towards risk which is encapsulated in the form of the hedgers’ utility function. However, the literature typically uses only one form of utility ...
We are living in an age of information overload, where it can be difficult to define which information is relevant and important to the end user at a point in time. In this paper, we introduce a solution to apportioning ...
The last ten years has seen the introduction and rapid growth of a market in weather derivatives, financial instruments whose payoffs are determined by the outcome of an underlying weather metric. These instruments allow ...
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 ...
We examine whether the hedging effectiveness of crude oil futures is affected by asymmetry in the return distribution by applying tail specific metrics to compare the hedging effectiveness of both short and long hedgers. ...
Price impact models are important for devising trade execution strategies. However, a proper characterization of price impacts is still lacking. This study models the price impact using an agent-based modeling approach. ...
Geographic diversification is fundamental to risk mitigation among investors and insurers of housing, mortgages, and mortgage-related derivatives. To characterize diversification potential, we provide estimates of integration, ...
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 ...
