Previous research concludes that options are mispriced based on the high average returns, CAPM alphas, and Sharpe ratios of various put selling strategies. One criticism of these conclusions is that these benchmarks are ill suited to handle the extreme statistical nature of option returns...

This paper studies the returns from investing in index options. Previous research documents significant average option returns, large CAPM alphas, and high Sharpe ratios, and concludes that put options are mispriced. We propose an alternative approach to evaluate the significance of option...

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 propose a novel factor model for option returns. Option exposures are estimated nonparametrically and factor risk premia can vary nonlinearly with states. The model is estimated using regressions, with minimal assumptions on factor and option return dynamics. Using index options, we...

In this paper, we develop an equilibrium framework to explain the characteristics of volatility index (VIX) futures prices and returns across maturities. In the framework, the investors prefer VIX futures with specific maturities, and the arbitrageurs optimize portfolios based on mean-variance...

In this paper we investigate VIX dynamics through a two-factor Gaussian model, following Avellaneda and Papanicolaou (2019). Two strategies were adopted. First, we considered constant market price of risk. Second, we included time-varying market price of risk. In both cases, we estimated the...

In perfectly frictionless and rational markets, spot markets and futures markets should simultaneously reflect new information. However, due to market imperfections, one of these markets may reflect information faster than the other and therefore may lead to the other. This study examines the...

For the first time in the Turkish stock market, the width of the zero arbitrage band for BIST 30 stock index arbitrage is measured and decomposed into distinct contributions arising from commissions, fees, bid/offer spreads and stock loan costs. This study also extends the literature of stock...

Using daily data, this paper empirically investigates the price discovery and information transmission in China's stock index futures and spot markets based on a VAR-GARCH model with SSAEPD margins. By comparing our model with classic VAR-GARCH model, we discover that our model can better...
