Michael Neumann, George Kapetanios and George Skiadopoulos – School of Economics and Finance, Queen Mary, university of London

This paper provides evidence that jumps in option prices exist and studies their real-time characteristics and drivers. To this end, options on the E-mini S&P 500 futures contract are employed. It is found that option prices jump independently from the underlying asset and that a fraction of jumps can be attributed to the release of news. However, it is illiquidity rather than the actual news content that drives option price jumps.
