摘要

摘要本文研究了新冠肺炎对全球五个流动性最强的期货市场的影响。我们对现货期货的小波相干分析结果揭示了两个重要的发现。首先,疫情期间现货期货的一致性运动在低频率和高频率范围内都有影响。其次,谱图显示了在大流行之前和期间的所有观察尺度上的混合因果关系方向。在套期保值有效性方面,OLS和VECM在套期保值的有效性方面有所改善。然而,小波方法的多尺度分析表明,由于疫情期间现货期货协会的不稳定性,套期保值的有效性取决于套期保值期。我们的研究结果驳斥了金融学者的传统观点,即在危机期间,现货和期货市场之间更紧密的联系可以提高套期保值的有效性。我们要强调的是,应经常审查投资篮子和对冲对,以优化结果。

Pandemic impact on the co-movement and hedging effectiveness of the global futures markets
ABSTRACT This paper examines the impact of COVID-19 on five of the world's most liquid futures markets. The results of our wavelet coherence analysis for spot futures reveal two important findings. First, spot futures coherence movements during the pandemic period are influential at both low and high frequency scales. Second, the spectrogram shows mixed causality directions at all scales of observation in the period before and during the pandemic. In terms of hedging effectiveness, OLS and VECM show improvements in hedging effectiveness. Nevertheless, multiscale analysis with wavelet methods shows that hedging effectiveness depends on the hedge period due to the instability of the spot-futures association during the pandemic period. Our results refute the conventional wisdom among finance scholars that a stronger link between spot and futures markets during the crisis improves hedging effectiveness. We would emphasise that investment baskets and hedge pairs should be reviewed frequently to optimise results.

期刊介绍: The Investment Analysts Journal is an international, peer-reviewed journal, publishing high-quality, original research three times a year. The journal publishes significant new research in finance and investments and seeks to establish a balance between theoretical and empirical studies. Papers written in any areas of finance, investment, accounting and economics will be considered for publication. All contributions are welcome but are subject to an objective selection procedure to ensure that published articles answer the criteria of scientific objectivity, importance and replicability. Readability and good writing style are important. No articles which have been published or are under review elsewhere will be considered. All submitted manuscripts are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is double blind and submission is via email. Accepted papers will then pass through originality checking software. The editors reserve the right to make the final decision with respect to publication.
