Jumps in option prices and their determinants : real-time evidence from the E-mini S&P 500 option market
Kapetanios, George; Neumann, Michael; Skiadopoulos, George - 2014
We study the real-time characteristics and drivers of jumps in option prices. To this end, we employ high frequency data from the 24-hour E-mini S&P 500 options market. We find that option prices do not jump simultaneously across strikes and maturities and are uncorrelated with jumps in the...

Positive stock information in out-of-the-money option prices
Gkionis, Konstantinos; Kostakis, Alexandros; … - 2018
We examine whether the option market leads the stock market with respect to positive in addition to negative price discovery. We document that out-of-themoney (OTM) option prices, which determine the Risk-Neutral Skewness (RNS) of the underlying stock return's distribution, can embed positive...

The contribution of transaction costs to expected stock returns : a novel measure
Hiraki, Kazuhiro; Skiadopoulos, George - 2023
We document that a theoretically founded, real-time, and easy-to-implement option-based measure, termed synthetic-stock difference (SSD), accurately estimates the part of stock's expected return arising from stock's transaction costs. We calculate SSD for U.S. optionable stocks. SSD can be more...

Pricing of idiosyncratic equity and variance risks
Gourier, Elise - 2016
This paper decomposes the risk premia of individual stocks into contributions from systematic and idiosyncratic risks. I introduce an affine jump-diffusion model, which accounts for both the factor structure of asset returns and that of the variance of idiosyncratic returns. The estimation is...

The contribution of frictions to expected returns
Hirakiy, Kazuhiro; Skiadopoulos, George - 2018
We derive a model-free option-based formula to estimate the contribution of market frictions to expected returns (CFER) within an asset pricing setting. We estimate CFER for the U.S. optionable stocks. We document that CFER is sizable, it predicts stock returns and it subsumes the effect of...

Returns in commodities futures markets and financial speculation : a multivariate GARCH approach
Manera, Matteo; Nicolini, Marcella; Vignati, Ilaria - 2012
This paper analyses futures prices for four energy commodities (light sweet crude oil, heating oil, gasoline and natural gas) and five agricultural commodities (corn, oats, soybean oil, soybeans and wheat), over the period 1986-2010. Using CCC and DCC multivariate GARCH models, we find that...
