Analysis of impact of Fundamental news on movement of index VIX
Koráb, Pavel ; Fičura, Milan (advisor) ; Vacek, Vladislav (referee)
The thesis investigates the impact of the fundamental news announcements on the movements of the VIX volatility index and the VIX Futures prices. The theoretical part of the thesis explains the construction of the VIX Index and the VIX Futures, describes the most important fundamental news for the US economy and presents a methodology for the modelling of the relationship between the news announcements and the VIX index movements with a simple linear regression model. In the empirical part of the thesis, we analyze the impact of 105 US fundamental news, from the Reuters Eikon database, on the VIX Index movements on theday of the news announcements as well as on the subsequent day. We find a strong relationship between the surprise component of the news and the VIX Index movements on the day of the news announcement, with the statistically significant news explaining 5-10% of the total return variance (for news with small number of observations up to 30-50%) on the announcement day. In the second part of the empirical study, simple trading system is proposed in order to utilize the possible impact of the economic news on the next-day (after announcement) returns of VIX futures in order to achieve speculative profits. Although the models seem to possess some limited out-sample profitability for some of the news, the results are for most of the cases statistically insignificant and the potential profits from the news trading seem to be relatively low.
