Climate Change Commitment and Stock Returns in the Gulf Cooperation Council (GCC) Countries

Stock returns are a critical aspect of investment decisions, and understanding whether climate change commitment influences stock returns is essential for informed decision-making. This paper investigates the impact of climate change commitment on the stock returns in the GCC countries for non-financial companies during the period of 2010–2023. The sample consisted of a total of 285 companies collected using the Refinitiv Eikon platform. The developed model was estimated using panel GMM regression. The results suggested that when companies reported their climate change commitment, it was appreciated by high demand for their stock and in turn caused the stock return to be higher. In addition, profitability and growth affect stock returns significantly positively, and this implies that investors concentrate on whether the company has higher profits and better growth prospects to demand more shares, and this affects the share prices positively. In addition, the size of a company has been found to affect the stock return positively, and this suggests that investors in the GCC feel confident in demanding the shares of large companies. Moreover, the results showed that leverage significantly negatively affects stock return, and this implies that investors interpret the position of highly leveraged companies to be bad due to worries that companies will not be able to service their loans. Such results might help investors to formulate their investment strategies and select their shares based on significant determinants. Finally, our results hold based on the reported robustness of results.
