ABSTRACT
Compiling a unique, worldwide collection of trading data, we analyze investor types' aggregate trading in stock markets throughout the COVID-19 episode, to assess investor types' role in a worldwide negative bubble and their degree of sophistication in responding to it. Individual investors were the main buyers and consequently the winners during the rebound. Foreign institutional investors exited host markets;some domestic institutions exploited the negative bubble by well-timed buying. In US index futures, asset managers heavily sold into crash;dealers profited from the rebound. Individual investors' buying was driven by their contrarian behavioral traits and a unique positive shock to retail investor demand for self-serviced investing in stocks, driven by work-from-home practices and unprecedented stimulus. This shock has changed the participant composition of world stock markets. Overall, the COVID-19 episode has many unique aspects that cannot be accounted for under existing theories.
ABSTRACT
PurposeThis study aims to investigate the interconnectedness across the risk appetite of distinct investor types in Borsa Istanbul. This study also examines the causal impact of global implied volatility indices on the risk appetite of these investor groups.Design/methodology/approachThe authors use a novel time-varying frequency connectedness framework of Chatziantoniou et al. and a new time-varying Granger causality test with a recursive evolving procedure by Shi et al. over June 2008 and July 2022.FindingsThe results show a high level of interconnectedness across the risk appetite of different investor types. The sizable spillovers to domestic types of investors either occur from professional or foreign investors, indicating the long-term dominant effect of foreign and more qualified investors on the domestic investors in Borsa Istanbul. The authors provide significant evidence of causality from the global implied volatility to the Borsa Istanbul risk appetite indices, which are getting stronger after the COVID-19 outbreak.Originality/valueUnlike the previous studies, the authors analyze the risk appetite sub-indices of various types of investors to reveal behavioral distinctions and interconnectedness across them. The authors use a novel econometric framework to assess investors' risk appetite in different investment horizons in a time-varying system. Together with volatility index (VIX), the authors also use volatilities of oil (OVX), gold (GVZ) and currency (EVZ), considering the information transmission not only from stock markets but also energy, metals and currency markets. The present data set covers significant financial crises, socioeconomic events and the COVID-19 outbreak.
ABSTRACT
This paper examines the effect of market investor types (institutional and non-institutional) on total market trade value in Saudi Arabia during the COVID-19 pandemic, including a three-month period of total containment. The research was conducted using a time series analysis method with an AutoRegressive Distributed Lag (ARDL), using weekly data collected from 7 January 2020 to 24 September 2020. The short-run result shows that both investor types net traded values and ownership holding values negatively impacts the development of Tadawul activity. Furthermore, the development of Tadawul activity showed a negative performance for the total containment period of three months. However, the long-run estimated model shows that, for both investor types, only net traded value has a positive significant impact on market activity development, whereas non-institutional ownership holding value development has a significant negative impact. Our results suggest fear is a mediator for the effect of COVID-19 on stock markets. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
