Yayın Cointegration and adjustment dynamics of REIT and stock markets during the global financial and European debt crises(Inderscience Publishers, 2020-06-03) Erol, Ümit; Yüksel, Sadettin Aydın; Yüksel, Aslı; Öztürk, HakkıThis paper analyses the cointegration relationship between the REIT and stock markets of ten developed countries during the 2005-2013 period, which is characterised by the global financial and the European debt crises. Given the structural breaks in the data, the effect of these two crises is examined separately by dividing the sample period into four equal parts and by using M-TAR cointegration analysis. The results suggest that the cointegration between the stock and REIT markets was not a globally observed feature prior to the twin crises. The strong and globally valid cointegration observed after 2007 was due to the common negative response of both markets to the unexpected massive shocks. These shocks also led to bilateral causality and strong feedback effects between these two markets, thus strictly limiting the diversification benefits of the REIT market during the crisis period.Yayın The impact of expectations on the co-integration relationship between the stock and REIT markets(Inderscience Publishers, 2022-06-29) Ümit, Erol; Yüksel, Aydın; Yüksel, Aslı; Öztürk, HakkıThis paper examines if expectations have a significant impact on the co-integration relationship between stock and real estate investment trust markets. We use two widely followed expectation indicators which are the US yield spread and the expected US stock market volatility (VIX) to test this hypothesis. The US yield spread is decomposed into two components which are the expected short-term interest rate (EF) and a variable term premium (TP) using Hamilton-Kim algorithm. A dataset covering ten developed markets is used. Using co-integration score analysis our findings indicate that expected US short-term interest rates and expected US stock market volatility have a statistically significant and positive impact on the global co-integrations of different countries. This effect is especially valid in the post-global financial crisis period. The expectation-based indicators EF and VIX, however, do not seem to have a significant impact on co-integration at regional and local levels.Yayın Global risk aversion and emerging market return comovements(Elsevier Science SA, 2018-12) Demirer, Rıza; Omay, Tolga; Yüksel, Aslı; Yüksel, Sadettin AydınUtilizing the recently developed measure of global risk aversion by Xu (2017), we show that global risk aversion is a significant determinant of international equity correlations, consistently across all emerging markets examined. The positive effect of risk aversion on emerging market comovements is particularly strong for South Africa and Turkey and is consistent with contagion effects. The results underscore the importance of non-cash flow shocks in models of contagion and portfolio risk.Yayın Granger causality relation between interest rates and stock markets evidence from emerging markets(European Journal of Business and Social Sciences, 2014-01) Teker, Dilek; Aykaç, Alp, ElçinThis research analyses the granger cause relation between interest rates and stock market for four emerging markets as Turkey, Brasil, China and Hungary. The database includes daily prices of stock market indices of BIST100 Index (Turkey), the IBOV Index (Brasil), the SHCOMP Index (China), and the BUX Index (Hungary) and government securities with different maturities. As the initial step, the stationarity of the variables is tested with Augmented DickeyFuller (ADF) and Phillips-Perron (PP) unit root tests. Then Granger Causality is implemented.Yayın Elections and stock market returns: evidence from Borsa Istanbul(Marmara Üniversitesi, 2023-06-22) Kayaçetin, Nuri VolkanStock prices may display predictable patterns around major political events, particularly in emerging market economies where political risk is a key component of asset risk premiums. One distinct event that would be expected to result in an abrupt increase in political risk is elections. Motivated by this notion, we study the returns for a set of indicator and sectoral indices of Borsa Istanbul stocks and the U.S. Dollar–Turkish Lira exchange rate around political elections held in Turkey over 2001–2020. Our tests reveal an accumulation of economically and statistically significant positive abnormal returns for all Borsa Istanbul stock indices and negative abnormal returns for the U.S. Dollar–Turkish Lira exchange rate over a window that starts as early as a month before the election date and extends for two weeks into the post-election period, with the effect being particularly strong in the week that immediately follows the election. Consistent with a political risk-based story, volatility of index returns starts increasing over the same period and plateaus out at a level that is roughly one-and-a-half to two-folds greater than its pre-election period average.
