Little is known about the economic sources that may generate the abnormal returns observed in put index options. We show that the learning process followed by investors may be one such source. We develop an equilibrium model under partial information in which a rational Bayesian learner prices...

A key issue in understanding option pricing is the response of option implied volatility to macro-economic announcements. We use high frequency data on ASX SPI 200 Index Options to examine the response of option implied volatility, as well as higher moments of the underlying return distribution,...

The aim of this paper is twofold: to investigate how the information content of implied volatility varies according to moneyness and option type and to compare option-based forecasts with historical volatility. The different information content of implied volatility is examined for the most...

In this paper, we introduce two classes of indices which can be used to measure the market perception concerning the degree of dependency that exists between a set of random variables, representing different stock prices at a fixed future date. The construction of these measures is based on the...

Equity options are not only an attractive trading vehicle due to the high leverage they offer, they also enable investors to trade their volatility expectations. With high-resolution option data, we analyze the volatility information embedded in index options with different moneyness and...

We develop a general model to price VIX futures contracts. The model is adapted to test both the constant elasticity of variance (CEV) and the Cox–Ingersoll–Ross formulations, with and without jumps. Empirical tests on VIX futures prices provide out-of-sample estimates within 2% of the...

This paper examines the time series economic determinants of Standard & Poor's (S&P) 500 Index option-implied risk-neutral distributions for the period 1998–2007. In particular, we investigate the effects of a market default likelihood index, which is computed by aggregating daily default risk...

We examine the effects of limited investor attention on stock returns by using Google search volume index to measure investor attention. We also investigate whether national culture and market development have any role in this relationship. We find that the impact of investor attention on stock...

This study compares the performances of neural network and Black-Scholes models in pricing BIST30 (Borsa Istanbul) index call and put options with different volatility forecasting approaches. Since the volatility is the key parameter in pricing options, GARCH (Generalized Autoregressive...
