    Does mood affect institutional herding?
    (Elsevier, 2020) Gavriilidis, Konstantinos; Kallinterakis, Vasileios; Öztürkkal, Belma
    Drawing on a unique data set of daily portfolio holdings for Turkish mutual funds we investigate the relationship between mood and institutional herding on the premises of various established mood proxies (weekend effect; holiday effect; Ramadan; sunshine). Results indicate that fund managers in Turkey herd significantly, with their herding growing in magnitude as the number of active funds per stock rises and appearing stronger on the buy-than the sell-side. Although the relationship of mood with institutional herding occasionally assumes the correct sign as per theoretical expectations, institutional herding is found to be insignificantly different across various mood states, thus denoting that mood does not impact the propensity of fund managers to herd.

    A Survey Analysis on the Investment Attitudes of Individual Investors
    (Bilgesel Yayincilik San & Tic Ltd, 2013) Öztürkkal, Belma
    This study aims to analyze determinants of trading behavior of individual investors where a survey of 55 questions on 85 people is used. The survey is composed of four parts: demographic properties perceived emotions investment preferences portfolio diversification. The findings show that investors are subject to home bias and the surveyed investors prefer to invest in local equity market. The findings show that older investors have less investment confidence and more diversification where number of different stocks and HHI (Hezfindahl-Hirshman Index) are used as two diversification measures in the analysis. The OLS regression and logit response results prove that male investors trade more and when the investor's equity portion of the total portfolios increases the number of trades also increases. The self-reported investment confidence level and greed have positive effect on diversification. Hence diversification level increases with the investor's equity portion of their total portfolios. The findings suggest that male investors on the average are more confident than females in their investment decisions and males who are more confident have better portfolio diversification choices.

    The Relationship Between Firm Size and Export Sales: Sector or Size What Matters?
    (Physica-Verlag, 2017) Berk, Niyazi; Öztürkkal, Belma
    This paper examines the performance of export focused companies listed on the Borsa Istanbul trading in the emerging market of Turkey. Using the panel data of stock market prices (1995–2011) we study the performance of companies in different sectors and their return performance in the volatile exchange rate environment and devaluation periods of 1996 1997 1998 1999 2001 and 2008. The paper investigates sales market capitalization or asset performances’ statistical significance level with regard to these companies’ export level. We review the performance of these operational measures in an environment of changing foreign exchange rates. Regression analysis is used to measure the effects of currency devaluation on the companies analyzed. Finally the study analyzes the export sales of companies by sector following a period of sharp devaluation. © Springer International Publishing AG 2017.

    Investigating Gender Gap in Editorial Boards of Finance Journals: A Social Network Perspective
    (Springer International Publishing AG, 2025) Tarantola, Claudia; Bedowska-Sojka, Barbara; Mare, Codruta; Paccagnini, Alessia; Ozturkkal, Belma; Pisoni, Galena; Skaftadottir, Hanna Kristin
    This study explores gender disparities and network connections among Finance journal editors worldwide, focusing on the crucial role these editors play in shaping academic fields and promoting diversity and equity in publishing. Despite efforts by publishers to present gender profiles and maintain balance in reviewer selection, significant gender imbalances persist, particularly affecting women's representation on editorial boards. Utilizing network analysis, the study documents the prevalence of a few highly connected editors and underscores the gender disparity in editorial roles, highlighting the need for policy interventions to enhance diversity and inclusion. Utilizing various typological metrics, we identify a core group of highly interconnected editors who hold positions on multiple boards. The gender distribution remains skewed towards men, even among editors with central roles or those serving on numerous boards. This research underscores the persistent gender gaps within academic publishing networks and calls for a deeper understanding and remediation of these disparities to foster diversity and equity in the academic landscape.

    Contagion of Fear: Is the Impact of Covid-19 on Sovereign Risk Really Indiscriminate?
    (Wiley, 2021) Cevik, Serhan; Ozturkkal, Belma
    This paper investigates the impact of infectious diseases on the evolution of sovereign credit default swap (CDS) spreads for a panel of 77 countries. Using annual data over 2004-2020, we find that infectious-disease outbreaks have no discernible effect on CDS spreads, after controlling for macroeconomic and institutional factors. However, a granular analysis using high-frequency data indicates that the COVID-19 pandemic has had a significant impact on CDS spreads. This adverse effect appears to be more pronounced in advanced economies, which may reflect the greater severity of the pandemic and depth of the economic crisis in these countries, at least during the initial stage of the outbreak, as well as underreporting in developing countries due to differences in testing availability and institutional capacity. While more stringent containment measures help lower sovereign CDS spreads, the fiscal burden of these efforts could undermine credit worthiness and eventually push the cost of borrowing higher.

    Perceived Financial Needs, Income Sources, and Subjective Financial Well-Being in an Emerging Market
    (Springer Publishing Co, 2019) Kiymaza, Halil; Öztürkkal, Belma
    This study investigates perceived financial needs and subjective financial well-being using data from a national survey of 2,567 households in Turkey. Financial needs are measured by consumer perceived ability to meet current living expenses in the short-term as well as their assessment for the retirement security in the long-term. We also investigate how income sources are related to subjective financial well-being. Findings show that households' daily concerns including the inability to meet short-term expenses including healthcare, daily living expenses (food and utilities), and the inability to maintain the existing living standard are highly significant factors in explaining their subjective financial well-being. We also find that having enough income during retirement and ability to find a job in the future are positively related to subjective financial well-being. Finally, when households ' incomes are from work, rental properties, family, and pension, they feel more financially secure.

    Explaining Mortgage Defaults Using Shap and Lasso
    (Springer, 2024) Ozturkkal, Belma; Wahlstrom, Ranik Raaen; Wahlstrøm, Ranik Raaen
    We utilize machine learning methods to model the credit risk of mortgages in a significant emerging market. For this purpose, we investigate a multitude of variables that explain the characteristics of the loans, the demographics of the borrowers, and macroeconomic factors. We employ SHapley Additive exPlanations (SHAP) values in conjunction with five different tree-based machine learning methods, as well as the least absolute shrinkage and selection operator (LASSO) in conjunction with logistic regressions. Our findings, which are robust across two sampling schemes, reveal that while demographic variables are significant and important, loan-specific and macroeconomic variables are the most crucial in explaining mortgage defaults. As existing literature on mortgage default has primarily focused on advanced markets, we aim to bridge this gap by concentrating on emerging market data. We also share our code, which we hope will encourage others to utilize the methods we have applied.

    The Role of Environmental, Social, Governance (ESG) Practices and Ownership on Firm Performance in Emerging Markets
    (Routledge Journals, Taylor & Francis Ltd, 2023) Bilyay-Erdogan, Seda; Ozturkkal, Belma
    This paper investigates: (i) the effect of environmental, social, and governance (ESG) engagement and ownership attributes on firm performance and (ii) whether different ownership attributes (institutional, foreign, and state ownership) moderate the association between ESG engagement and firm performance. Employing an extensive sample from 22 emerging countries worldwide, we provide cross-country evidence that ESG engagement and its three pillars, i.e. environmental, social, and governance pillars, enhance firm performance, proxied with ROA and Tobin's Q. Moreover, institutional and foreign ownership positively impact firm performance. We present novel evidence that the positive impact of superior ESG engagement on firm performance is lower for higher institutional ownership companies than lower institutional ownership companies, but greater for higher foreign ownership companies than lower foreign ownership companies.

    Art Investment: Hedging or Safe Haven Through Financial Crises
    (Springer, 2020) Öztürkkal, Belma; Toğan-Eğrican, Aslı
    We analyze long-term art auction sales data focusing on and around financial crisis periods with other investment returns to understand whether art can be considered a safe haven during volatile times or a hedging option in general by analyzing art auction data in a volatile emerging market. Our findings suggest Turkish art returns are either negatively correlated or at low correlation with other investments, including the equity market. We have the view that art can be considered a hedging mechanism on average to enhance returns and to decrease the risk of portfolios and improve diversification. However, we do not discard the safe-haven hypothesis, either. Although the auction data on the crisis period is limited, results of and around crisis periods show art returns are positively correlated with various volatility indices. In addition, the number of art transactions also increases after the crisis years, which may be a sign of liquidity requirement of some investors and an opportunity for buyers. The benefit is visible especially during years of contractions, which do not end with a very severe crisis, since the art auction market liquidity dries if the crisis is severe.
