Inefficiencies in the fiscal and monetary systems of the Ottoman Empire led to a higher debt burden over time and the bankruptcy for the Ottoman state in 1875. To deal with these inefficiencies, reforms were implemented: supervisory organizations were established and the gold standard was adopted. How did investors at the Istanbul Bourse view these reforms? We manually collected data on the price of Ottoman government bonds on the Bourse from 1873 to 1883. Using the generalized autoregressive conditional heteroscedasticity (GARCH) methodology, we identify short-run and permanent changes in volatility of bond returns subsequent to the reforms. Our results suggest investors responded positively, by accepting lower yield premia, to adoption of the gold standard, and foundation of the Ottoman Public Debt Administration which had European sponsors, but did not respond positively to reforms that relied on purely local institutions.

Intraday volatility characteristics throughout the trading week are examined at the emerging Borsa Istanbul (BIST) stock exchange. Using five-minute (and 15-minute) intervals, accentuated intraday volatility patterns at the microstructure level are examined during the stock market open and close in the morning and in the afternoon sessions. Volatility is highest when markets open in the morning. The second highest is during the afternoon open. The third highest is before the market closes for the day. Volatility before the market close has increased in recent years. These characteristics are seen every trading day. There are also differences: Monday returns are lowest, Friday returns are highest, and Monday morning volatility is highest of the entire trading week. Day-of-the-week and intraday accentuated volatility smile anomalies are jointly investigated using the longest intraday sample period in the emerging country stock exchange literature. Investment companies and professionals can utilize the results for risk management and hedging by avoiding highly volatile opening and closing periods. Arbitrageurs, speculators, and risk takers should trade during these highly volatile periods. Heightened volatility is increased difficulty in price discovery, thus inefficiency. Market participants, exchanges, and public prefer efficient markets. The research presents evidence of trading days, and periods during the trading day, when the exchange becomes more efficient. This is the first research that explores day-of-the-week effect from intraday volatility perspective in an emerging market, and provides useful recommendations in designing risk management strategies at market microstructure level.

This paper aims to develop a ranking methodology for the companies included in the Islamic indices in Turkey. Thus, this paper simplifies the decision-making process for investors with Islamic sensitivities to stock market investment when constructing their investment portfolio.

This paper uses a case study of 20 companies listed on Borsa Istanbul, drawing data from their 2017, 2018 and 2019 financial reports. These companies are scored and ranked according to their compatibility with the screening criteria used by Ziraat Katilim index in Turkey. In addition, this paper uses the quantitative screening process to calculate the ranking scores of these companies.

The findings show that some companies are highly compatible with the screening criteria, with ranking scores close to 100 points. However, some companies satisfied the criteria on the margin. This may not be a desirable result for some investors.

Only 20 companies are included in the analysis. Since the conventional accounting system is used in Turkey, it was difficult to get exact information about the companies’ Sharīʿah compatibility from the financial results.

The findings assist investors to determine which company is ethically more responsible than others within the Islamic framework. There are also implications for the companies in question, index providers and Sharīʿah scholars.

The findings aim to simplify the decision-making process of investors who have Islamic sensitivities to stock exchange market investment when they constitute their portfolio.

To the best of the authors’ knowledge, it is one of the first attempts to develop a ranking methodology for Sharīʿah-screened stocks in Turkey even though Sharīʿah screening has been on the agenda since the late 1990s. This paper also compares 11 indices based on their screening criteria.

This study investigates the impact of simultaneously replacing both midday single-price call auction and lunch break with multi-price continuous trading on intraday volatility–volume patterns as well as the intraday volatility–volume nexus.

The analysis utilises 150 m tick-by-tick transaction data related to 333 stocks traded on Borsa Istanbul Equity Market covering a period of 2 months prior to and following the change. In addition to graphic comparisons, the study uses difference in mean tests, panel-fixed generalized least squares (GLS), panel-random GLS and random-effects linear models with AR(1) disturbance regression estimations.

The results show that intraday volatility and trading volume form an inverse J-shape and are positively correlated. It is observed that the implementation of the regulation change decreased intraday volatility and increased trading volume. Additionally, the results indicate a negative volatility–liquidity and a positive volume–liquidity relationship, supporting the mixture of distribution hypothesis.

Enhanced market efficiency provides greater opportunity for investment and risk management. Investors can benefit from the findings on the intraday volatility–volume nexus, which is an indicator of informed trading, and regulatory authorities can use volume to oversight volatility.

This very rare regulation change of the simultaneous replacement of the lunch break and midday call auction with continuous trading is investigated in the context of intraday volume and volatility. This study also expands upon some important findings on the volume–volatility nexus for the Turkish Stock Market.

The aim of the study is to examine the influence of remuneration committee (RC) characteristics, namely separation, size, independence, meetings, and female directors, on firm performance (FP) by using return on assets (ROA), return on equity (ROE) and earnings per shares (EPS). The study covers all firms being listed in Bahrain Bourse for two years which are 2020 and 2021. The results of the study show that having more directors in RC would significantly increase firm performance “ROE and EPS.” Further, having more females in RC would significantly increase firm performance “ROA.” In addition, having separate RC would significantly decrease firm performance “ROA and EPS.” Moreover, the independence of directors in RC and its frequent meetings has no significant impact on the firm’s performance. The results show that there is a need to re-evaluate the role of the RC and strengthen its effectiveness, as some of the variables examined by this study have an insignificant impact on a firm’s performance. Further, there is a need to allocate additional efforts and policies in developing corporate governance and RCs as well.

This study aims to investigate the Ramadan effect anomaly on the stock markets’ indices and estimate the movement of these indices in the light of the phenomenon.

Stock market indices are used as financial indicators to show the Ramadan effect. To validate this effect, eight Arab countries, which comprises Jordan, Saudi Arabia, Oman, Qatar, United Arab Emirates, Bahrain, Kuwait and Egypt, are adopted. A linear regression with R², error, F-value and p-value is considered to analyze and understand the effect of Ramadan on the aforementioned Arab countries.

Results found that Ramadan has a strong effect on estimating and predicting the performance of stock market indices in all studied Arab countries, except Kuwait. Results found that the majority of the Ramadan effect occurred after the second 10 days of Ramadan, where the direction of stock indices is opposite of Ramadan variables in all aforementioned cases.

This study is considered as an enrichment of the existing literature review with regard to the Ramadan effect. The study presents a new methodology that can be followed to improve the predictions of stock market indices by using a weight least square method with linear regression. This study presents the most affected periods of time that could decrease or increase the stock prices. Finally, the study proves the capability of the weight least square method in building a predictive model that takes the date into consideration in predicting stock market indices.

This paper aims to consider data for listed companies in Bahrain Bourse to determine whether companies practice earnings management (EM). Further, the effect of a set of corporate governance characteristics on EM practices is examined.

The EM level was measured using discretionary accruals (DA) [calculated using the Modified Jones (1995) Model]. The study sample consisted of 20 companies listed during the period 2011-2015. Panel regression model was used to test the study hypotheses and achieve the study aims.

EM is negatively correlated with board size, confirming that a larger board is associated with a lower level of EM practices. Further, board independence is positively correlated with EM, suggesting that the larger the number of independent directors, the higher the level of EM practices. In addition, internal ownership is positively related to EM, confirming that the higher level of internal ownership increases EM practices. CEO duality does not appear to have any effect on EM in Bahrain Bourse. More interestingly, the findings reveal that companies practice EM through income-increasing DA.

Financial data and data related to other corporate governance characteristics are lacking.

The results of this study provide empirical support for the development of new regulations and amendments and necessary corrective decisions regarding the effectiveness of applying corporate governance code in Bahrain Bourse. More specifically, this study reveals an urgent need for new amendments to restrict EM practices in Bahrain Bourse.

This study enriches the EM literature by covering Bahrain as an Asian country, which has not been sufficiently examined in relation to this topic. Further, this study provides a clear picture of the level of EM practices in Bahrain Bourse to multiple parties.

The purpose of this paper is to investigate the association between online financial disclosure (OFD) and firms’ performance in the Gulf Cooperation Council (GCC).

Extensive literature review was carried out and a checklist of 90 items (71 for content and 19 for presentation) was developed to measure the level of OFD by the firms that are listed in financial sectors of the GCC Bourses.

The findings show that the overall OFD in GCC is 77 percent. The results indicate a positive association between OFD and firms’ performance.

The study recommends that regulatory bodies should develop a guideline of disclosing information through the internet in order to enhance the corporate transparency and performance among the GCC listed companies leading to reasonable economic decision making.

Additionally, the study contributes to financial reporting and performance literature relating to the GCC countries.
