We examine the effect of the Capital Market Authority’s decision to cancel an entire day’s trades on the returns of listed banks. To investigate the impact of this event, we use the event-study method and apply it over a defined period. Our results provide evidence of a significant negative effect from the cancellation of a day’s trading on banks’ returns over the examined period. However, further analysis indicates that this effect turned insignificant once additional announcements that found favour with investors were made. These findings confirm the harmful cost of cancellation decision that first-ever happened in the financial markets.

This study investigates the effect of a failed terror attack on stock market returns using an event study approach. The mean-adjusted returns and the market model are used to analyse the event. The results show that the failed attack on the Pakistan Stock Exchange building in Karachi generated positive cumulative returns for all the listed stocks, suggesting that such events have positive effects on stock market returns.

The outcome of carbon disclosure, the importance of which has grown remarkably in recent years to become a strategic decision‐making issue for organisations in today's competitive environment, is a subject of lively debate but remains under‐researched in the environmental accounting literature. This study is motivated by this research gap and the growing interest in assessing the financial consequences of corporate involvement in climate change beyond regulatory compliance, as evidenced by firms' voluntary participation in the Carbon Disclosure Project. Using the resource‐based view of the firm as a theoretical framework and linking it to carbon disclosure through Carbon Disclosure Project, we conceptualise and empirically investigate the impact of adopting proactive carbon management policies and communicating them to stakeholders, focusing on the financial performance of the top FTSE350 companies between 2007 and 2015. By developing a comprehensive financial performance index and controlling for several firm characteristics, we find strong evidence that voluntary carbon disclosure is positively associated with firm financial performance. The findings in this paper provide new insights and policy implications for managers, financial stakeholders, and regulators.
