We consider a tractable affine stochastic volatility model that generalizes the seminal Heston (1993) model by … variance, and we examine the impact of the distribution of jumps on the associated implied volatility smile. We provide … sufficient conditions for the asymptotic behavior of the implied volatility of variance for small and large strikes. In …

We provide first-time evidence of 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...

We propose two new risk measures (i-beta and i-gamma) for a stock, which aim to distinguish between noise and information. Noise allows the stock price evolution to happen along a continuous path. Market wide economic information is transmitted via price jumps. Noise is idiosyncratic and does...
