Yayın Do stock splits matter for returns, volatility, and liquidity? New evidence from Borsa Istanbul(SSBFNET, 2021) Gümüş, Nihat; Gümüş, Nihat; Gümüş, Nihat; Gümüş Çağlayan, Ayşe; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme BölümüThe purpose of this study is to investigate the impact of stock splits on the return, riskiness, and liquidity of stocks. Utilizing a sample of 94 stock splits taken place between 2010 and 2019 at Borsa Istanbul, the study analyzes the daily abnormal returns, change in volatility, and changes in volume around the stock split announcement and execution dates. The results display significant positive abnormal returns around the announcement date but not significant abnormal returns around the execution. The volatility and liquidity of stocks increase significantly around both announcement and execution dates. The findings are in line with the positive signaling, and liquidity hypotheses of stock split and with most of the observations reported in the empirical literature. The new evidence provided points out the lack of semi-strong form of market efficiency at Borsa Istanbul as far as the stock splits are considered.Yayın Unveiling the dynamics: Exploring the relationship between emerging stock market prices and macroeconomic indicators through ARDL analysis(Econometric Research Association (ERA), 2024) Gümüş, Nihat; Baba, Murtala Mustapha; Yönetim Bilimleri Fakültesi, İşletme BölümüUsing a panel ARDL model, this study examines the relationship between stock prices and prices in other marketplaces. Examining data for 19 emerging market nations from January 2004 to December 2022, the study investigates how gold prices, interest rates, exchange rates, and inflation affect stock prices. With the exception of gold, the data show a persistently negative association between the variables in the long run. Short-term impacts are negligible overall, with the exception of gold's drawbacks. The 2008 global financial crisis had a short- and long-term negative impact on emerging market stock markets. The COVID-19 epidemic first caused stock market returns to decline, but eventually these effects reverse. In order to promote long-term growth in stock markets, this study emphasizes the significance of prudent fiscal policies meant to lessen government domination in financial markets and solid monetary policies centered on price stability.Yayın How profitability differs between conventional and Islamic banks: A dynamic panel data approach(Elsevier, 2018) Gümüş, Nihat; Yanıkkaya, Halit; Pabuççu, Yaşar Uğur; Gümüş, Nihat; Yönetim Bilimleri Fakültesi, İşletme BölümüThis paper analyzes and compares the dynamics for the profitability of conventional banks and Islamic banks in the Organization of Islamic Cooperation countries and the United Kingdom between 2007 and 2013 using a sample of 74 Islamic and 354 conventional commercial banks. “Net interest margin” and “return on asset” are employed as variables representing the profitability and several new explanatory variables are introduced such as, the usage of self-service banking channels, penetration of financial services, crude oil/agriculture price indexes and asset ratio of non-Murabahah assets of Islamic Banking. Dynamic panel data estimates indicate that almost all explanatory variables of profitability for conventional and Islamic banks are different implying that profitability of Islamic banks relies on the different dynamics than that of conventional ones. Both profitability measures are not persistent over time and neither of them has significant relationship with the country specific macroeconomic variables. Estimation results imply the importance of new product and alternative channel development in enhancing the profitability of Islamic banks. Moreover, our analysis shows that the usage of products which promotes more risk sharing as compared to the products based on Murabahah structure can contribute to the performance of Islamic banks.
