Using a broad set of news reports about the Greek sovereign crisis, we tested for the impact of the troika bailout programs on the banking, financial, and real economic sectors of the Athens Stock Exchange (ASE). Our results reveal that the troika’s actions caused a shift in the systematic...

We identify crucial events during the European sovereign debt crisis and investigate their impact on the euro currency. In particular, we analyse how specific announcements related to vulnerable Eurozone member states, European Central Bank (ECB) actions, and credit rating downgrades affect the...

We study the real-time characteristics and drivers of jumps in option prices. To this end, we employ high frequency data from the 24-hour E-mini S&P 500 options market. We find that option prices do not jump simultaneously across strikes and maturities and are uncorrelated with jumps in the...
