In this project we employ multivariate GARCH models with smooth transition in conditional correlation to investigate market efficiency of Turkish Derivatives Exchange. For the period June 2005-August 2013, we model the dynamic return correlations of “stock index futures” and “currency futures” with their underlying spot returns to uncover the timing and reasons of deviations from perfect correlation. Besides, the role of global volatility, market specific volatility and market trends, which are thought to affect correlation levels, are examined. The empirical results imply that the conditional correlations of stock index futures have increasing trend and reach to 0.95 levels which reveal that the market is efficient. But for currency futures we cannot find evidence of upward trend, the structure of correlation has a dynamic nature and fluctuate around 0.65. Thus it is not enough to conclude that they are efficient or to conclude that they are inefficient.

Margin call risk management with furures and options Alıravcı, Murat; Duran, Sever; Tanrısever, Fehmi; Department of Industrial Engineering (2013) This study examines dynamic hedge policy of a company in a multi-period framework. The company begins to operate a project for a customer and it also has a subcontractor which completes an important part of the project by using an economic commodity. The customer will pay a fixed price to the company at the end of the project. Meanwhile, the company needs to pay the debt to the subcontractor and the amount of the debt depends on the spot price of the commodity at that time. The company is allowed to hedge f...
Currency and asset substitution in Turkey Taşdemir, Özlem; Özmen, Erdal; Department of Economics (2003) This study investigates the determinants and effects of currency and asset substitution in Turkey using quarterly data from 1987:1 to 2002:4. The empirical results from the application of Johansen procedure to a four-variable system containing currency-asset substitution proxy (M2Y/M2)), real income, real exchange rate, and ratchet effect proxy (past peak values of the depreciation of the real exchange rate) suggest the presence of a single cointegration vector among the variables. The results further sugge...
Türkiye döviz piyasalarında oynaklığın öngörülmesi ve risk yönetimi kapsamında değerlendirilmesi Ülkem, Başdaş; Soytaş, Uğur (2010-01-01) Bu çalışmada, Türkiye döviz piyasalarında TRL/USD, TRL/EUR ve TRL/GBP serilerinin oynaklığı hareketli ortalama modelleri, AR ve ARMA modelleri ve ARCH süreçleri kullanılarak modellenmiş ve modellerin örneklem dışı öngörü performansları karşılaştırılmıştır. Farklı oynaklık öngörüleri kullanılarak elde edilen parametrik VaR modelinin öngörü performansları Basle Komitesi geriye dönük test ölçütleri kapsamında değerlendirilmiştir. Son küresel finansal krizin risk ölçüm teknikleri üzerindeki etkileri ayrıca...
Risk measurement, management and option pricing via a new log-normal sum approximation method Zeytun, Serkan; Uğur, Ömür; Korn, Ralf; Department of Financial Mathematics (2012) In this thesis we mainly focused on the usage of the Conditional Value-at-Risk (CVaR) in risk management and on the pricing of the arithmetic average basket and Asian options in the Black-Scholes framework via a new log-normal sum approximation method. Firstly, we worked on the linearization procedure of the CVaR proposed by Rockafellar and Uryasev. We constructed an optimization problem with the objective of maximizing the expected return under a CVaR constraint. Due to possible intermediate payments we as...
Stock market liquidity analysis: evidence from the İstanbul Stock Exchange Özdemir, Duygu; Gaygısız Lajunen, Esma; Department of Economics (2011) The purpose of this thesis is to identify the factors playing a key role in the determination of the Turkish stock market liquidity in aggregate terms in a time series context and discuss the joint dynamics of the market-wide liquidity with its selected determinants and the trade volume. The main determinants tested are the level of return, the return volatility and the monetary stance of the Central Bank of the Republic of Turkey. The expected positive relationship between the liquidity and the return is c...
