Also, price jumps originating in mature EU or U.S. markets mostly explain large local price changes in the Central and Eastern European (CEE) emerging markets.
Recent developments in information technologies allow markets to operate at ever-increasing speed that allows more efficient information processing. Thus, modern research relies on using intraday data and allows researchers to study the impact of macroeconomic news announcements, as well as company-specific news on assets including equities, commodities, bonds, and financial derivatives (Bollerslev and Cai 2000; Erenburg, Kurov, and Lasser 2005; Jones, Lin, and Masih 2005; Nikkinen, Omran, Sahlström, and Äijö 2006; Rigobon and Sack 2008).
