Increasing market volatility and the profound impacts of climate change require a comprehensive understanding of how weather affects stock market performance. This paper aims to investigate the effect of eight weather conditions (clear sky, precipitation, pressure, temperature, relative humidity, specific humidity, wind direction, and wind speed) on the returns of major African stock markets (Botswana, Cote d’Ivoire, Kenya, Mauritius, Morocco, Namibia, Nigeria, Rwanda, South Africa, Tanzania, Tunisia, Uganda and Zambia) over the period from January 2, 1998 to December 30, 2023. Using daily data and a GJR-GARCH (1,1) model with an AR process, the findings reveal that weather conditions influence all African stock markets. Specifically, the markets are categorized according to their sensitivity to weather conditions into three groups: highly affected (5-7 coefficients with 0.001≤ p <0.05), moderately affected (3-4 coefficients with 0.001≤ p <0.05), and slightly affected (1-2 coefficients with 0.001≤ p <0.05). Mauritius and Uganda emerge as the most weather-sensitive countries, with significant impacts (0.001≤ p <0.05) for seven of the eight weather conditions studied. Understanding the relationship between weather conditions and African stock markets enables investors to adjust their strategies and better manage their portfolios to optimize return opportunities. Ultimately, this study provides essential insights for investors, portfolio managers, and financial decision-makers, aiding them in better assessing the risks and opportunities associated with weather conditions in African stock markets, thereby enhancing their decision-making and investment management.

Investment Management and Financial Innovations Volume 18, 2021 Issue #3 pp. 334-346 Views: 7429 Downloads: 3507 TO CITE АНОТАЦІЯThis paper aims to examine the impact of the COVID-19 outbreak on Indian firms listed on the NSE and analyze its impact on various sectors. In addition, a sub-sample analysis based on market capitalization was performed to understand the effect of size during extreme events. The sample consisted of 1,335 firms listed on the NSE India. A standard event study outlined by Brown and Warner (1985) was employed to analyze the price impact on the COVID-19 outbreak. The event windows from -10 days to +10 days were selected. The estimation window is 250 days. The Nifty 50 has been chosen as a proxy for market return. The sample firms witnessed a negative impact of the COVID-19 outbreak with a negative CAAR in different event windows. In addition, various sectors are classified according their responsiveness towards the COVID-19 outbreak into three groups: highly negatively affected, moderately negatively affected, and slightly negatively affected. The paper also points out that the pandemic substantially affects the above-median market capitalized firms than the below-median market capitalized firms, which contradicts the size effect phenomenon. The results assist shareholders in managing their portfolios and mitigate the systematic risk of their investments during extreme events such as a pandemic, wars, and others. This study is the first comprehensive analysis of the impact of the COVID-19 outbreak on different sectors in India. It is also the first study to investigate the size effect anomalies during extreme events.

Investment Management and Financial Innovations Volume 16, 2019 Issue #3 pp. 142-156 Views: 2463 Downloads: 436 TO CITE АНОТАЦІЯThe impact of news on individual investor decision is explicit as investors need to update, adapt and forecast returns with constraints of time, uncertainty and resources to be successful. The aim is to understand and review the influence of news on individual investor’s decision making in stock markets and identify the impact of different type of news on individual investor’s decision making in stock markets, assess the behavioral reaction and investment decisions made by investors before and after there is news item, identify the linking effect on behavioral theories and biases, develop a generalized decision making conceptual model to understand the impact of news on investor’s reaction, decision and its linkages along with the behavioral bias. Theoretical basis/methodology for processing of news by investors is assumed to be based on Broadbent’s filter theory (1958) and due to cognitive informational inefficiency of investors it assesses the attention and the investor’s reaction of overreaction and underreaction, which do not comply with efficient market hypothesis theory. The reasons for its noncompliance are found by relating it with behavioral theories. The results explain how investor screens with filters and give attention to news only when it affects their portfolio or investment objective and strategies. It is concluded that investor’s decision making depends on degree of information penetration, information content, information influence, specific internal factors and generic external and on investors prevailing at that given circumstances. This gives us the solution to comprehend the investor’s reaction, decision and unresolved reversals, short- and long-term overreaction.

Understanding the preference of individual retail investors on green bond in India: An empirical study

Investment Management and Financial Innovations Volume 18, 2021 Issue #1 pp. 177-189 Views: 2439 Downloads: 1016 TO CITE АНОТАЦІЯThe biggest challenge facing countries, including India, is creating and managing an LCR (low carbon resilient) economy, which balances the need for high growth rates and is environmentally sustainable. The green bond market provides investors the means to help change the economy into an LCR economy. The study was undertaken to understand the key drivers and the factors influencing the individual retail investor’s decision to invest in green bonds. A survey instrument was designed and administered through the snowball sampling technique to 125 Indian respondents of various age groups who were eligible to invest in the Indian bond market. SPSS software was used to conduct a descriptive analysis followed by regression and conjoint analyses. The study results suggest that the Environmental, Social, and Governance (ESG) rating and credit rating of the green bond issuers are the key factors that influence an individual’s investment decision. The findings also highlight that incentives such as tax exemptions and awareness of green bonds also affect an investor’s decision. This research stands out as one of the first attempts to understand the Indian retail investors’ perception of a green bond.
