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.

A behavioral analysis of investor diversification
(Routledge Journals Taylor & Francis Ltd, 2014) Fuertes, Ana-Maria; Muradoğlu, Gülnur; Öztürkkal, Belma
This paper studies the link between individual investors' portfolio diversification levels and various personal traits that proxy informational advantages and overconfidence. The analysis is based on objective data from the largest Turkish brokerage house tracking 59951 individual investors' accounts with a total of 3248654 million transactions over the period 2008-2010. Wealthier highly educated older investors working in the finance sector and those trading relatively often show higher diversification levels possibly because they are better equipped to obtain and process information. Finance professionals married investors and those placing high-volume orders through investment centers show poorer diversification possibly as a reflection of overconfidence. Our analysis reveals important nonlinear effects implying that the marginal impact of overconfidence on diversification is not uniform across investors but varies according to the investor's information gathering and processing abilities.

Behavioral Biases Of Finance Professionals: Turkish Evidence
(Elsevier Science Bv, 2016) Kiymaz, Halil; Öztürkkal, Belma; Akkemik, K. Ali
This study extends the existing literature on the determinants of behavioral biases of Turkish finance sector professionals. It examines the impact of various personal and objective attributes of finance sector professionals on their risk choices derived from their portfolio allocation and personal wealth data. Utilizing survey data from 206 professionals we find that these professionals take higher risk in the form of investment in equities when investing in home country firms (geographic bias) and investing in firms headquartered in their home towns (home bias). Those relying on their own predictions when making investment decisions and those with emotional biases invest less in equities. Findings further show that younger professionals professional with less education with lower risk aversion and with single broker accounts are more likely to invest in equities. We also find that those with higher expected returns invest more in equities showing overconfidence. Subsample analysis results for finance professionals suggest that portfolio managers and brokerage company professionals display differing risk taking behavior. (C) 2016 Elsevier B.V.

Choice of finance in an emerging market: The impact of independent decisions politics and religion
(Springer International Publishing, 2017) Davutyan, Nurhan; Öztürkkal, Belma
This paper is based on a KONDA 1 Research and Consultancy 2 survey conducted in May 2014 on 2607 people forming a representative sample of the Turkish population. It focuses on how people’s religious and political characteristics impact the independence of their decision making regarding saving and borrowing. An earlier study by Davutyan and Ozturkkal (2016) reports saving and borrowing decisions strongly correlate with income, education, marital status and region within country. Furthermore, 54% of those surveyed did not save and the main motivation for those who saved was to finance children’s education or home purchase. Religious people and those with a conservative lifestyle are less likely to borrow from family and friends. Older, married and working individuals are more likely to have difficulty paying back loans. According to the results of this survey, religious individuals are less likely to independently decide on their investment choices. Thus, religious people tend to make investment decisions together with family, elderly and respected relatives.

Determinants of Saving-Borrowing Decisions and Financial Inclusion in a High Middle Income Country: The Turkish Case
(Routledge Journals Taylor & Francis Ltd, 2016) Davutyan, Nurhan; Öztürkkal, Belma
We use a representative survey of the Turkish household sector and investigate factors impinging on saving-borrowing behavior. We run four probit regressions to elucidate (i) the saving decision (ii) asset choice or portfolio composition for those who save (iii) the bank loan decision and lastly (iv) the formal versus informal borrowing decision. We find income education marital status and region within country strongly correlate with those decisions. We offer some insights regarding the influence of variables like rural to urban migrant status and religious belief on saving and borrowing decisions. We discuss the long-term implications of our findings on the Turkish household savings performance.

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.

Effect of family controlled firms on cost of equity evidence of Turkish listed firms during 2008 financial crisis
(Kadir Has Üniversitesi, 2020) Qahtan, Abdulrahman; Öztürkkal, Belma
Önceki çalışmalar, şirket yönetiminin mali bir krizin, özellikle de bu kritik zamanlarda ortaya birçok ekonomik olgu koyan yakın zamandaki ekonomik krizlerin önlenmesinde ya da etkilerinin azaltılmasında başarısız olduğuna inanmıştır. Bu olaylardan biri de vasıta problemi ve hissedarlar arası el koyma meseleleridir. Bir önceki araştırmalar kriz zamanlarında, hissedarların çoğunluğunun azınlıkta olan hissedarların malına el koyma dürtüsünün genellikle böyle bir dürtünün daha az olduğu aile şirketi olmayan şirketlerin aksine aile ya da bireyler tarafından yönetilen şirketlerde gözlemlendiğini iddia etmektedir. Bu araştırma, aile şirketleri ile 2008 yılındaki ekonomik kriz zamanında sonuçta büyük bir rolü olan öz sermaye maliyetinde belirgin olan vasıta maliyeti arasındaki ilişkiyi incelemektedir. Veriler Türk menkul kıymetler borsasındaki 331 şirketi kapsayarak Bist All Share (XUTUM) halka açık şirketlerinden toplanmıştır. Zaman aralığı, 2008'deki ekonomik krizden iki yıl önce ve iki yıl sonra olmak üzere 2006'dan 2010'a kadarki zaman olarak belirlenip farklı yapısından ötürü mali sektörü dışarıda bırakarak mali verileri ve son mülkiyeti bir araya getirmede ikinci veri metodunu kullanarak belirlenmiştir Sonuçlar, Türkiye'deki aile kontrolündeki ve aile kontrolündeki olmayan firmaların özkaynak maliyetinde önemli bir fark olmadığını göstermektedir.

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.

Profit sharing between managers and investors: An experimental investigation
(Elsevier Science Bv, 2015) Öztürkkal, Belma
This study analyzes the effect of interest and power structures and conflict of interest among managers and investors and tests the effect of different payout mechanisms on willingness to pay. In this study 74 student subjects are involved in a setting where the manager is determining his own compensation. A series of experiments that vary managers' ability to determine their own compensation and investors' ability to punish inappropriate behavior are reported. The experiments involve pairs of subjects consisting of an investor and a manager with asymmetric decision making powers. When managers compensate themselves inappropriately investors' recourse is to shun the company's shares-a model that arguably corresponds more closely to reality than the accepted efficient market traditional paradigm. The experiment shows that managers share profits even when investors cannot withhold investment and investors fairly compensate managers as well. This pattern explains both the ability of capital markets to function despite the presence of inherent moral hazard and occasional managerial misbehavior.

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.

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.

A tournament analysis of mutual funds in Turkey
(Bilgesel Yayincilik San & Tic Ltd, 2012) Öztürkkal, Belma; Erdem, Orhan
This is an analysis of the mutual funds in Turkey with respect to their risk-altering behavior Using the monthly returns and volatilities of 133 funds from 2002 to 2007 we divide each year in two parts and check whether or not the funds' performance in the first part affects the behavior of mutual fund companies in the second part in terms of risk. We find sufficient evidence that the funds which have lower/higher performance in the first part of the year have higher/lower risk appetite for the second half of the year: The results have stronger significance if the year is divided from June or July. The results from the Turkish mutual funds market are generally in line with previous literature from developed countries.
