The objective of this study was to analyze and model periodic behavior observed in India's Nifty VIX Index and to seek the origins of these previously unreported calendar variations. Implied volatility and its variations are important to understand as the pricing of many financial assets and...

Over-the-counter foreign exchange options (OTC-FXOs) are the fourth largest derivatives market in the world. However, the extant literature on their pricing is noticeably thin. We propose a new discrete time exponential-affine multi-factor model, with multiple estimation strategies and pricing...

Seasoned equity offerings (SEOs) typically provide investors with information, or signals, that are stock price relevant. This information, however, is generally intangible, meaning market participants have incomplete knowledge about its quality. Investors thus tend to regard it as ambiguous. To...

We derive the theoretical relation between the term structure of implied variance and the expected excess returns of the underlying asset. Adopting three alternative approaches to compile the variables representing the information on the implied volatility index level and term structure, we show...

This article explores the role of the realized return distribution in the formation of the observed implied volatility smile using the framework of an adaptive expectations model. According to this framework investors update their expectations of future events, through which options are priced,...

We compile option-implied tail loss and gain measures based on a deep out-of-the- money option pricing formula derived by applying ‘extreme value theory', and then use these measures to investigate the information content of option-implied tail risk on the future returns of the underlying...

This paper develops a closed-form model for options on commodities under the assumptions of mean-reversion in the commodity prices and regime-switching in the commodity returns volatility. After a closed-form solution for the option value in constant regimes has been developed, the model is...

The challenge in long volatility strategies is to minimize the cost of carrying such insurance due to negative roll yields and negative volatility risk premia. This study proposes a hedging strategy for volatility as an asset class that provides substantial protection against market crashes,...

Financial markets are becoming increasingly event driven. These can take the form of economic releases, speeches and elections. The arrival of this new information often causes the underlying asset to jump. Consequently, the expectation of these known announcements can produce significant...
