This study tests and documents the information content of all publicly available implied volatility indices regarding both the realized volatility and the returns of the underlying asset. These topics present a path traveled by earlier work, but there are gains in studying together all 50...

This paper proposes a tail risk index, TIX, as the growth rate of the model-free cumulant generating function of market risk calculated from index option prices. It captures the power law decay rate of the left tail of future return distributions, and thus reflects market beliefs about the...

This article describes the primary uses of the VIX index in the financial literature, offering for the first time a joint view of its successes and failures in key financial areas. VIX is a model-free volatility index that measures the investor "fear" gauge due to its significant and negative...

Manipulation in the VIX settlement can cause significant losses to investors. Analysing high-frequency data, we present indications of VIX manipulation accelerating since 2017. Deviations have an upward direction and average at around 6%. Specific effects accompany settlement days. The put/call...

This study examines whether VIX futures prices are unbiased and efficient predictors of the VIX index. The particular empirical analysis differs from the usually applied tests in that it uses a panel estimation approach. Panel regression has several advantages as it offers more flexibility in...

We introduce and evaluate the NOVIX - an implied volatility index for the Norwegian equity index OBX. NOVIX is created according to the VIX methodology. We compare the NOVIX to the German VDAX-NEW and the U.S. VIX and find that NOVIX has similar properties as these two indices. We also evaluate...

The VIX index is not traded on the spot market. Hence, in contrast to other futures markets, the VIX futures contract and spot index are not linked by a no-arbitrage condition. We examine (a) whether predictability in the VIX index carries over to the futures market, and (b) whether there is...

Implied volatility and other forward-looking measures of option-implied uncertainty help investors carefully evaluate market sentiment and expectations. We construct several measures of implied uncertainty in European government bond futures. In the first part, we create new volatility indices,...

Investors utility has been mathematically modeled at 1738 by Daniel Bernoulli as an attempt to capture investors preferences to lottery outcomes. Ever since the analysis of decision making under uncertainty has again become a major focus of interest. Kahneman and Tversky in 1979 suggested a more...
