Proceedings of 32nd International Business Research Conference 23 - 25 November, 2015, Rendezvous Hotel, Melbourne, Australia ISBN: 978-1-922069-89-4 The Volatility Spillovers between Sectors of Turkish Stock Market on The Basis of Financial Crises Güven Sevil, Melik Kamışlı and Serap Kamışlı Abstract The volatility spillovers between markets give information to investors to be used in investment decisions. Especially risk averse investors use these information in diversification and portfolio allocation decisions. But some investors want to invest in specific sectors. So, it will be useful to analyze the relations between sectors. On the other hand, crises can change the direction of volatility spillovers between the sectors and investors should take into account these changes to give right investment decisions. In this context, the purpose of this study is to analyze the volatility spillovers between industrial, services and financial sectors of Turkish stock market which is named Borsa Istanbul, on the basis of 2008 Global Crisis and Greece Debt Crisis. The analysis covers three periods that are determined according to the crises. The first period is before the Global Crisis (2001-2008), the second is after the Global Crisis (2008-2009) and the third one is after the Greece Debt Crisis (2009-2015). Daily index returns are analyzed by causality in variance test which is proposed by Hafner and Herwartz (2006). The findings reveal that there are reciprocal volatility spillovers between industrial and financial sectors and unidirectional spillover from services to industrial sector before the 2008 Global Crisis. But there is no spillover between the index returns after the Global Crisis. It is also determined there are volatility spillovers from industrial sector to services and financial sectors and from services to financial sector. The results show that crises change the volatility linkages between sector index returns.
