European Natural Gas Seasonal Effects on Futures Hedging
2015
Abstract This paper is the first to discuss the design of futures hedging strategies in European natural gas markets (NBP, TTF and Zeebrugge). A common feature of energy prices is that conditional mean and volatility are driven by seasonal trends due to weather, demand, and storage level seasonalities. This paper follows and extends the Ederington and Salas (2008) framework and considers seasonalities in mean and volatility when minimum variance hedge ratios are computed. Our results show that hedging effectiveness is much higher when the seasonal pattern in spot price changes is approximated with lagged values of the basis (futures price minus spot price). This fact remains true for short …
WHY MOST FIRMS CHOOSE LINEAR HEDGING STRATEGIES
2009
I investigate the efficiency of alternative hedging strategies of nonfinancial firms facing hedgeable price risk, unhedgeable quantity risk, and financial contracting costs in low-profit events. The analysis suggests that variance-minimizing hedging strategies are very close in economic terms to optimal, value-maximizing hedging strategies for most firms. Furthermore, the marginal gains from shifting to nonlinear hedging strategies are often small enough to be neglected. These results illuminate some puzzling findings in survey studies of firms’ hedging practices and suggest an alternative view on firms’ selective hedging practices termed “cautious selective hedging.”
Essays On European Natural Gas Market
2018
La presente tesis ha cubierto diferentes aspectos de los mercados europeos del gas natural y la electricidad, en particular algunas propiedades que afectan a la efectividad de la cobertura, como la estacionalidad en varianza y en precios. Asimismo, se ha realizado un estudio de la prima de riesgo del gas natural, su relación con las variables de riesgo y su descomposición en una prima de riesgo de reinversión o ‘rollover’ y una prima de ‘preferencia por liquidez’ relacionada con el plazo. La tesis se compone de tres capítulos: el Capítulo I estudia la estacionalidad en los precios y la volatilidad y cómo mejora la efectividad de la cobertura teniendo en cuenta dicha estacionalidad; el Capít…
