An Empirical model of the international cost of equity

Uzunkaya, Mehmet
The aim of the study is to propose an empirical model of the international cost of equity by investigating and analyzing the long-run relation between disaggregated country risk ratings and country stock market index returns for a large panel of countries. The study tests the hypothesis that, given the available theoretical and empirical evidence, country risk ratings and country stock market index returns should move together in the long-run and there should be a long-run equilibrium between them; thus country risk ratings, with their forward-looking nature about the political, macroeconomic and financial fundamentals of a large number of countries, may behave as long-run state variables for stock returns to the extent they are undiversifiable internationally. The results of the analysis provide evidence in favor of the argument that disaggregated country risk ratings, in particular the political and economic risk ratings, are related to stock market returns in the long-run. Using this relation, an empirical model of the international cost of equity is proposed. The model takes country risk ratings as inputs and finds the international cost of equity for a specific country of known risk ratings.


An Investigation on the nature of the idiosyncratic risk of stock portfolios
Kocaarslan, Barış; Soytaş, Uğur; Department of Business Administration (2018)
In this study, based on sound economic theories, two economic transmission channels are identified to investigate the impacts of changes in funding liquidity conditions in interbank loan markets and the reserve currency (US dollar) value on the idiosyncratic portfolio-level risks. Controlling for business cycles, we find that a deterioration in funding liquidity conditions increases the idiosyncratic risk of high-risk portfolios more than that of less risky portfolios. This increase is stronger when the idi...
Testing for rational bubbles in the Turkish stock market
Başoğlu, Fatma; Sezer, Ali Devin; Department of Financial Mathematics (2012)
In this thesis we empirically examine whether the Turkish stock market is driven by rational bubbles over the period between March 1990 and February 2012. The bubble periods are estimated using a recently developed right-tailed unit root test, the generalized sup augmented Dickey-Fuller test of Phillips, Shi and Yu (2011a). Applying their bubble detection and location strategies to weekly price dividend ratio series, we find strong evidence for the existence of rational bubbles in the Turkish stock market b...
An Analysis of momentum and mean reversion effects on equity indices
Özbilge, Armağan; Yolcu Okur, Yeliz; Nazlıben, Kamil Korhan; Department of Financial Mathematics (2015)
Momentum and mean-reversion effects have become very popular in finance literature for the last two decades since their presence can generate abnormal profit patterns by applying either relative strength or contrarian trading strategy accordingly. Even though there are some common factor explanations for return reversals, they might not provide the full picture for return persistence. In our theoretical framework, we analyse some of the well-known discrete time momentum studies including the initial one and...
A Test of multi-index asset pricing models: the case of Istanbul Stock Exchange
Kalaç, Sırrı Selim; Danışoğlu, Seza; Department of Business Administration (2012)
This study employs widely excepted asset pricing models to test their explanatory power in the context of Istanbul Stock Exchange listed companies between 1990 and 2010. The risk factors, beta, size, book-to-market equity, and momentum are used to form portfolios and their factor loadings are estimated. The results of this study are mostly in line with the previous academic research, and some unique attributes of the return generation mechanism of Istanbul Stock Exchange are reported.
An analysis of stock splitz in the İstanbul Stock Exchange
Yılmaz, Işıl Sevilay; Rhoades, Seza Danışoğlu; Department of Business Administration (2003)
The primary purpose of this study is to test the validity of the trading range hypothesis as a basis for stock split decisions of Turkish companies. In the first part, the liquidity effects of stock splits on Turkish stocks are examined. Second, the optimal trading ranges for different-sized firms and firms with different investor bases are determined. Finally, the main empirical question of the study is analyzed by testing whether or not Turkish firms whose share prices rise above their optimal trading ran...
