Çeşitli yatırımcı gruplarının hisse senedi alım-satım işlemleri ve pazar getirisi arasındaki etkileşim
(2015) Gültekin, Melis; Umutlu, Mehmet
Finans literatüründeki birçok çalışmada portföy yatırımları ile endeks getirisi arasındaki ilişki veya etkileşim incelenmiştir. Fakat bu çalışmaların birçoğu aylık veya yıllık frekansta gerçekleştirilmiş olup, dar bir yatırımcı sınıflandırması altında yapılmıştır. Bu tez çalışmasında üç farklı yatırımcı grubunun hisse senedi alım-satım işlemleri ile Pazar getirisi arasındaki etkileşim günlük frekansta ve Kore Borsası'nda KOSPI200 incelenmiştir. Vektör Ardışık Bağlanım (VAR) yöntemi ile yapılan analiz sonuçlarına göre yabancı ve bireysel yatırımcıların momentum yatırım stratejisi izlediği görülürken, kurumsal yatırımcıların zıtlık stratejisi izlediği bulunmuştur. Kriz döneminde ise, kurumsal ve bireysel yatırımcıların yatırım stratejilerini değiştirmedikleri görülmüştür. Diğer taraftan, kriz döneminde tüm dönemde olduğu gibi yabancı yatırımcıların net alımları ile geçmiş endeks getirileri arasında pozitif yönde bir korelasyon olduğu, fakat tüm dönemden farklı olarak bu korelasyonun istatistiksel olarak anlamlı olmadığı bulunmuştur.
Essays on Financial Development in Emerging Countries
(2022) Gültekin, Melis; Umutlu, Mehmet
Financial development plays a part in the enhancement of growth, and its goal is to decrease poverty. If a country develops its financial system, it will improve its functions by improving public services, productivity, wealth, and increasing savings, and access to credits. In the first chapter of this dissertation, financial development and its determinants are explained in detail. It is discussed why financial development is important for emerging countries, and how it can be accomplished and sustained. In the second chapter, the association between financial development and financial openness is analyzed by using panel data regression for 27 emerging countries from 1996 to 2016. The second Chapter especially emphasizes three different financial openness measures which are trade, capital account and stock market openness. This issue is particularly important for emerging markets trying to improve their financial system to raise much-needed capital for investment projects. The financial development variable is measured by three different ratios: stock market capitalization/GDP, liquid liabilities/GDP, and private credits/GDP. Alternative measures are also employed for trade and capital account openness. Moreover, capital flow-based and valuation-based variables used in this chapter for measuring stock market openness have not been employed to explain financial development in the literature before. Empirical results suggest that openness to trade and openness to the capital account are the key factors for accomplishing financial development. These outcomes are also robust to the use of alternative financial development and financial openness variables and after controlling for institutional quality and its sub-components. The results of this chapter will have implications for policymakers in emerging markets who endeavor to raise the depth of their financial markets for easier and cheaper access to funds. In Chapter Three, the long-run association between financial development and economic growth is investigated by performing the Johansen-Fisher panel cointegration method for 27 emerging countries between the years 1980 to 2018. The Vector Error Correction Method (VECM) is also applied to determine the direction of a causal relationship between economic growth and financial development The two components of the overall financial development index developed by Svirydzenka (2016) (financial institutions index and financial markets index) are used to discover through which channels economic growth has a long-term association with financial development. This multi-dimensional variable explains the nature of financial development more inclusively than other alternative measures. This chapter's empirical outcomes suggest that there is a significant long-run relationship between economic growth, the overall financial development index, and its sub-indices. Likewise, outcomes from panel VECMs display a unidirectional causality between economic growth and the overall financial development index whereas bidirectional causality occurs among economic growth, financial institutions and financial markets indices. These outcomes are also robust to the use of Pedroni and Kao panel cointegration tests. The outcomes reveal that both financial markets and financial institutions have a significant effect on economic growth in the long run. Hence, the results of this chapter have implications for policymakers in emerging markets who try to develop economic growth.
