P59 - Comparative Economic Systems: OtherReturn

In this paper, we employ the high-frequency data from Prague Stock Exchange (PSE) and New York Stock Exchange (NYSE) to analyse the variation in extreme price movements and market volatility around the period of fall of Lehman Brothers. The sample ranges from January 2008 to July 2009. We employ the price jump indicators optimal with respect to Type-I and Type-II errors. The former one shows an increase in market volatility and extreme price movements during financial distress, while the later one distinguishes extreme price movements and shows that they do not react in the long-run to fi nancial distress at PSE, while for the matured US market suggests a company/sector-specific reaction. We analyse behaviour of extreme price movements with respect to CDS. Our results suggest that both markets are different - extreme price movements at PSE are independent of CDS movements, while those at NYSE show a sector/company specific reactions to CDS.

We analyze effect of intraday information flow in three emerging EU stock markets-the Czech Republic, Hungary, and Poland. We use five-minute intraday data on stock market index returns and 15 types of EU and U.S. macroeconomic announcements during 2004-2007. We measure each announcement as its difference from market expectation. Mean and variance equations are jointly estimated. We bring evidence of strong spillovers from matured stock markets as well as effects of the macroeconomic news originating thereby. We find varying effects of the real economy news. Information on current account and prices has strong effect across all markets. We find limited evidence of the economic climate news and no evidence of the monetary announcements. Volatility of the returns is accounted for at the beginning and end of the trading session and it declines dramatically during the rest of the day. The three emerging markets react to information flow in a similar manner as matured markets.
