摘要

在金融极度动荡时期,投资者会将对冲和避险资产纳入其投资组合。目前的研究着眼于危机期间黄金回报与全球股市回报之间的动态联系。该研究考察了世界股市和黄金回报率之间的条件相关性。该研究利用每日MSCI股票指数和黄金价格数据,调查了2001年1月至2021年6月熊市期间黄金作为股票避风港的实用性。本研究将危机期定义为熊市,并使用Pagan和Sossounov(2003)的算法识别熊市。为了研究的目的,确定了七个熊市。采用DCC-GARCH模型和OLS回归相结合的方法确定黄金与MSCI世界股票指数之间的关系。研究发现,在被调查的熊市中,动态条件相关性主要是负的。除了2004年2月27日至2004年6月30日的熊市外,黄金在所有熊市中都扮演着避风港的角色。得出的结论是,在动荡时期,黄金是一种稳健的避险资产,而避险资产取决于股价变化的严重程度。研究结果对政策制定者和投资者具有启示意义。

Testing the role of gold in crisis: a global perspective
During the period of extreme financial turmoil, investors will include hedge and safehaven assets in their portfolios. The present study looked at the dynamic link between gold return and the world stock return during crises. The study examined the conditional correlation between world stock and gold return. It investigated the usefulness of gold as a safe haven for stocks in the bear markets from January 2001 to June 2021 using daily MSCI stock index and gold price data. The crisis period is defined as the bear stock market in the present study, and bear markets were identified using the algorithm of Pagan and Sossounov (2003). Seven bear markets were identified for the purpose of the study. A combination of the DCC-GARCH model and OLS regression were employed to determine the relationship between gold and the MSCI world stock index. The study found that the dynamic conditional correlations are primarily negative in the bear markets under investigation. Gold performs the role of a safe haven for all bear markets except for the bear market from 2004-02-27 to 2004-06-30. It was concluded that gold acts as a robust, safe haven during turmoil and safe haven property depends on the severity of stock price changes. The findings have implications for policymakers and investors.
