Abstract
Purpose
The study endeavours to determine (1) whether the disposition effect exists among South African investor teams, (2) whether it is causally intensified by a set of psychosocial factors and (3) whether the disposition effect causally reduces investor welfare.
Design/methodology/approach
Following a natural field experimentation design involving a sample of investor teams participating in the 2019 run of the JSE University Investment Challenge, the authors use regression adjustments as well as bootstrap tests to investigate the casual implications of a set of psychosocial factors on the intensity of the disposition effect, as well on the attenuation of market-adjusted ex post returns (i.e. investor welfare).
Findings
South African investor teams are susceptible to the disposition effect, and their susceptibility to the bias is associated with attenuated investor welfare. Furthermore, low female representation in an investor team causally intensifies the disposition effect, subsequently leading to a causal reduction in investor welfare.
Originality/value
Using evidence from real-world observation, the authors contribute to the literature on team gender diversity and investment decision-making, and – using Hofstede's (2001) cultural dimensions – the authors offer a comprehensive account for how differences in culture may lead to differences in gender-related disposition effects across different nationalities. The authors also introduce to the literature experimental evidence from the field that clearly demonstrates that – among South African investor teams – a causal relationship exists (1) between female representation and the disposition effect, and (2) between the disposition effect and investor welfare.

Abstract
Purpose
This paper operationalizes insecurity and governance crises to study their effects on stock market response to two political events in Nigeria – the 2015 and 2019 presidential elections.
Design/methodology/approach
An event study was used to capture the market responses. Abnormal returns at the aggregate and sectoral levels were measured over several time windows before and after the respective election results were announced.
Findings
The market reacted strongly positively to a change in presidency from an incumbent to an opposition party candidate in the 2015 election but weakly positively, at best, to the re-election of the incumbent candidate in the 2019 election. In addition, banking stocks exhibited greater sensitivity to these events than oil and gas stocks.
Research limitations/implications
There may be peculiarities with the Nigerian case and with the two elections analyzed. Therefore, future research could focus on understanding the extent to which the results generalize to the broader sub-Saharan context and other regions that face similar governance challenges.
Practical implications
Understanding that markets may have a different perception towards incumbent versus opposition candidate electoral victories during periods of insecurity and governance crisis is important for investors, policymakers, researchers and the wider society.
Originality/value
Past empirical studies on political events and stock returns in Sub-Saharan Africa contexts such as Nigeria ignore shifts in voter mood and produce contradictory findings. This paper helps to resolve some of these contradictions by providing insight into how the markets can have a different perception towards incumbent and opposition candidate electoral victories during periods of insecurity and governance crisis.

Abstract
Purpose
As women increasingly take on leadership roles during these turbulent times, the differences in their leadership styles in comparison to males in similar positions will continue to attract attention as it has in the past. The aim of this paper is to explore appropriate leadership styles that women in senior leadership positions facing the glass cliff have at their disposal.
Design/methodology/approach
This research method was qualitative. Data was collected through semi-structured interviews from a total of 17 participants in corporate South Africa; purposive and snowball sampling was used to select women in senior leadership positions.
Findings
Participants expressed overwhelming support for a transformational leadership style due to its characteristics; however, women leaders believe a style or combination of styles are used based on the situation at hand.
Research limitations/implications
Using only qualitative research has limited the scope and applicability of this study significantly.
Practical implications
The representation of women in senior leadership positions has increased over the years more especially in organisations where there is crisis, attention now is the difference in kind of leadership styles they use.
Originality/value
Very few research studies have gone in-depth into the effectiveness of the leadership styles that were used by women in corporate South Africa. The study, therefore, presents a major implication indicating that to show positive results, women need to be able to identify an appropriate leadership style based on carefully reviewing their specific organisational situation.

Abstract
Purpose
This paper explores how a firm's public stand on a social-political issue can be a salient signal of the firm's values, identity and reputation. In particular, it investigates how boycott participation–conceptualized as a cue of a corporation's stand on important social-political issues–may affect the stock market valuation of that corporation, as well as how corporations legitimise their stand on the issues.
Design/methodology/approach
The authors employ a mixed-methods design that uses both qualitative techniques (content analysis) and quantitative methods (event study methodology) to examine a sample of US firms who participated in a boycott campaign that sought to call attention to issues of hate speech, misinformation and discriminatory content on social media platform Facebook.
Findings
Findings from the qualitative content analysis of company statements show that firms legitimise their stand on, and participation in, the boycott by expressing altruistic values and suggesting to stakeholders that their stand aligns not only with organizational values/convictions but also with the greater social good. Importantly, the event study results show that firms who publicly announced their intention to participate in the boycott, on average, earn a statistically significant positive abnormal stock return of 2.68% in the four days immediately after their announcements.
Research limitations/implications
Findings relate to a specific case of a boycott campaign. Also, the sample size is limited and restricted to US stocks. The signalling value of corporate social advocacy actions may vary across countries due to institutional and cultural differences. Market reaction may also be different for issues that are more charged than the ones examined in this study. Therefore, future research might investigate other markets, use larger sample sizes and consider a broader range of social-political issues.
Practical implications
The presence of significant stock price changes for firms that publicly announced their decision to side with activists on the issue of hate propaganda and misinformation offers potentially valuable insights on the timing of trades for investors and arbitrageurs. Insights from the study also provide a practical resource that can be used to inform organizations' decision-making about such issues.
Social implications
Taking the lead to push on social-political issues, such as hate propaganda, discrimination, among others, and communicating their stands in a way that speaks to their values and identity, could be rewarding for companies.
Originality/value
This study provides novel evidence on the impact that corporate stances on important social-political issues can have on stock market valuation of firms and therefore extends the existing related research which until now has focused on the impact on consumer purchasing intent and brand loyalty.

Abstract
Purpose
The purpose of this study is to explore how citizen protests against perceived acts of racial injustice impact on share prices of companies who weigh in on the protests. In particular, corporate statements that directly address the issues around the protests are identified and possible mechanisms underlying how these may impact shareholder value are discussed.
Design/methodology/approach
The authors first use a qualitative research approach of content and sentiment analysis to track how companies or their chief executive officers (CEOs) present their stance against racial injustice, as represented by their use of linguistic markers. Then, the authors use an event study methodology to assess the response from stock market participants.
Findings
The findings suggest that CEOs primarily convey their stance using language that is emotive and empathic. In addition, shareholders earn a significant abnormal return of 2.13%, on average, in the three days following the release of the statements.
Research limitations/implications
This study considered only US-listed companies. The sample size, also, is relatively small. Institutional and cultural differences across countries may also vary. Thus, future research could explore the extent to which the findings generalize to other contexts.
Practical implications
Results provide insights to top managers who communicate with various stakeholders on emotionally charged social issues. Findings also offer insights on the timing of trades for investors and arbitrageurs.
Social implications
Findings contribute to the understanding of corporate behaviour in times of social upheaval. Insights from the study may also be used to inform corporate communication decisions about important social issues.
Originality/value
This study brings into focus the role that affective appeal and moral emotion can play in evoking motivation for corporate activism, and the impact that this has on investor opinions’ formation process.

Abstract
Purpose
The purpose of this paper is to investigate investor herding behaviour and the effect of presidential elections on investor herding behaviour in African stock markets at the sector level.
Design/methodology/approach
The study segregates listed firms into financial, consumer goods, consumer services and basic materials sectors and uses the cross-sectional absolute deviation approach as a metric of detecting herding in each of the sectors. The authors extend the model to tease out the effect of presidential elections on investor herding behaviour.
Findings
The study reveals that sectoral differences are fundamental to the evolution of herding. Herding is prominent in a financial services sector dominated by banks. The phenomenon also prevails in markets with smaller consumer goods and services sectors. A post-presidential election effect on investor herding is found for the consumer goods and services sectors of Ghana and a pre-presidential election effect is documented in Nigeria's consumer services sector. The authors conclude that post-presidential election effect is as a result of political connections whilst a pre-presidential election effect is attributable to political business cycles.
Research limitations/implications
The study is based on four African countries due to data constraints. Nonetheless, the study is the first in Africa to the best of the authors' knowledge, and the results are very solid and have a lot of practical and policy implications.
Practical implications
The study has implications for investors as it guides investment behaviour in pre- and post-presidential election periods.
Originality/value
Past studies on investor herding behaviour in African stock markets have largely concentrated on the aggregate market. Knowledge on sectoral differences in investor herding is almost non-existent for African stock markets. Furthermore, premised on the fact that stock markets react to presidential elections, there is no known study that have attempted to examine the effect of presidential elections on investor herding behaviour. This paper contributes to the literature by providing evidence on sectoral differences in investor herding behaviour and the effect of presidential elections on sectoral herding behaviour.

Abstract
Purpose
This study investigated the interactive impact of global and domestic stock market variables on the depth of the financial system in Sub-Saharan African (SSA) countries from 1990 to 2018.
Design/methodology/approach
The study used the mean group and pooled mean group estimators for the dynamic heterogeneous panel.
Findings
The results provide strong statistical evidence that the depth of the financial system in SSA countries is influenced by a combination of local and international stock market indicators. While the local variables exert a positive influence, the global indicator tends to negatively affect the depth of the system, particularly the monetization ratio.
Practical implications
While the tendency of portfolio adjustments and reversal can be inferred, the study stresses the need for a more globalized approach to financial policy formulation and implementation even as the trend of global financializaton gets more robust and more profound.
Originality/value
This study is unique in that, unlike prior ones, it has extended the debate on the role of the stock market in financial deepening from a domestic to an international dimension. Financial policy making can be aided by the authors' findings through looking at the financial deepening-stock market linkage from both domestic and globalized perspectives.
