The ultimate goal of this study is to forecast the BIST-100 Price Index using its mostly significative macroeconomic and financial determinants. For this aim, we have adopted an exhaustive search algorithm which takes the advantage of theoretical candidate variables to find the possible effects of these variables on the BIST-100 Price Index. The algorithm, which is built in the form of linear ARIMAX models, is to exploit every possible combination of explanatory variables to capture the behaviour of the index over the time period from 2002 to 2013 using monthly based data. To this end, best models have been obtained out of a huge number of models with regard to Akaike and Bayesian information criteria. The model with minimum AIC value outperforms the model with minimum BIC value with respect to root mean square error measure. Moreover, the 2Y Turkish bond interest rate, the DAX and Bovespa Indices are the best explanatory variables found to estimate the index. Besides, out-of-sample testing has been implemented over the 2014-2015 time period.

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...
Ambiguity and asset pricing: An empirical investigation for an emerging market Sahin, Baki Cem; Danışoğlu, Seza (2022-11-01) This study explores the impact of ambiguity on returns of both individual stocks and stock portfolios in an emerging market setting. First, an ambiguity index is derived and then the sensitivity of stock returns to am-biguity is analyzed while controlling for the other risk factors commonly cited in the literature. Results show that stocks with a high (low) sensitivity to ambiguity generate higher (lower) excess returns. These results are intuitive in the sense that investors seem to ask for lower returns f...
Information in the financial news: effect of market commentary on stock market performance Giray, Aynur; Danışoğlu, Seza; Department of Business Administration (2012) This paper studies the effect of investment sentiment on asset prices. A sentiment proxy is calculated by performing content analysis on the Wall Street Journal‘s "Heard on the Street‘ columns. This proxy is extracted by the principal component analysis of the word tags from the Harvard psychological dictionary that is used by the content analysis software General Inquirer. The relationship between stock prices, trading volume and the media sentiment proxy is estimated within the VAR context. Results sugges...
Local volatility model applied to BIST30 european warrants: pricing and hedging Kirazoğlu, Zekiye Sıla; Sezer, Ali Devin; Department of Financial Mathematics (2016) One of the basic observations on pricing options is that the assumption of constant volatility does not agree with data and market price data gives a volatility smile that depends on maturities and strike prices. The ﬁrst model that developed to be compatible with this observation is the local volatility model. The purpose of this work is to study the performance of the local volatility model on BIST30 warrants and compare it to the standard Black Scholes model. To estimate the local volatility model from d...
How does the stock market volatility change after inception of futures trading? Esen, İnci; Danışoğlu, Seza; Department of Financial Mathematics (2007) As the trading volume in TURKDEX, the first and only options and futures exchange in Turkey, increases, it becomes more important to have an understanding of the effect of stock index futures trading on the underlying spot market volatility. In this respect, this thesis analyzes the effect of ISE-National 30 index futures contract trading on the underlying stocks’ volatility. In this thesis, spot portfolio volatility is decomposed into two components and this decomposition is applied to a single-factor retu...
