Does Risk-Neutral Skewness Predict the CrossSection of Equity Option Portfolio Returns?
نویسندگان
چکیده
We investigate the pricing of risk-neutral skewness in the stock options market by creating skewness assets comprised of two option positions (one long and one short) and a position in the underlying stock. The assets are created such that exposure to changes in the underlying stock price (delta) and exposure to changes in implied volatility (vega) are removed, isolating the effect of skewness. We find a strong negative relation between risk-neutral skewness and the skewness asset returns, consistent with a positive skewness preference. The returns are not explained by well-known market, size, book-to-market, momentum, short-term reversal, volatility, or option market factors.

Robust Portfolio Optimization with risk measure CVAR under MGH distribution in DEA models
Financial returns exhibit stylized facts such as leptokurtosis, skewness and heavy-tailness. Regarding this behavior, in this paper, we apply multivariate generalized hyperbolic (mGH) distribution for portfolio modeling and performance evaluation, using conditional value at risk (CVaR) as a risk measure and allocating best weights for portfolio selection. Moreover, a robust portfolio optimizati...

In the first chapter ``Gold, Platinum, and Expected Stock Returns'', I show that the ratio of gold to platinum prices (GP) reveals variation in risk and proxies for an important economic state variable. GP predicts future stock returns in the time-series and explains variation in average stock returns in the cross-section. GP outperforms existing predictors and similar patterns are found in int...

We find important differences in dollar-based and dollar-neutral G10 carry trades. Dollar-neutral trades have positive average returns, are highly negatively skewed, are correlated with risk factors, and exhibit considerable downside risk. In contrast, a diversified dollar-carry portfolio has a higher average excess return, a higher Sharpe ratio, minimal skewness, is unconditionally uncorrelate...

In this paper, we aim at developing a model for option pricing to reduce the risks associated with Ethiopian commodity prices fluctuations. We used the daily closed Unwashed Lekempti grade 5 (ULK5) coffee and Whitish Wollega Sesame Seed Grade3 (WWSS3) prices obtained from Ethiopia commodity exchange (ECX) market to analyse the prices fluctuations.The natures of log-returns of the prices exhibit a...
متن کاملForecasting the mean and volatility of stock returns from option prices
In this paper we suggest a unified framework to predict the mean and volatility of stock log-returns from option prices adjusted for risk premium effects, which is free from any option pricing model. Based on this, the paper shows that both the physical mean and volatility do not correspond one-to-one to their risk neutral cumulants but depend on higher order cumulants, such as the third and th...
