, especially on the BS implied volatility. Implied binomial trees (IBT) models capture the variations of the implied volatility … known as "volatility smile". They provide a discrete approximation to the continuous risk neutral process for the underlying … Barle and Cakici (BC). After the formation of IBT we can estimate the implied local volatility and the state price density …

We develop a discrete-time stochastic volatility option pricing model, which exploits the information contained in high …-frequency data. The Realized Volatility (RV) is used as a proxy of the unobservable log-returns volatility. We model its dynamics by … competing time-varying (i.e. GARCH-type) and stochastic volatility pricing models. The pricing improvement can be ascribed to …

decomposing realized volatility in its continuous and discontinuous jump component. First, we analyze the relation between … volatility and trading activity. Coherent with existing studies we find that the driving factor of the relation between … Data ; Realized Volatility ; Price Jump ; Trading Activity ; Urgent Market Message …

Stocks are exposed to the risk of sudden downward jumps. Additionally, a crash in one stock (or index) can increase the risk of crashes in other stocks (or indices). Our paper explicitly takes this contagion risk into account and studies its impact on the portfolio decision of a CRRA investor...

We study whether prices of traded options contain information about future extreme market events. Our option-implied conditional expectation of market loss due to tail events, or tail loss measure, predicts future market returns, magnitude, and probability of the market crashes, beyond and above...

Empirically, we document a strong global … hypothesis that financial intermediaries are marginal investors in the variance swap market. …

This paper studies the information content of the S&P 500 and VIX markets on the volatility of the S&P 500 returns. We … risk-neutral distributions as well as the term structure of volatility smiles and of variance risk premia. We find that the …

This paper investigates how technical trading systems exploit the momentum and reversal effects in the S&P 500 spot and futures market. The former is exploited by trend-following models, while the latter by contrarian models. In total, the performance of 2580 widely used models is analyzed. When...

Considering buyer-initiated and seller-initiated trades and … investigate whether buyer and seller initiated trades as two factors of realized volatility, we investigate whether they have an … asymmetric effect on realized volatility. The stocks in the ASX50 sampled over the period January 1996 to April 2010 reveal that …

A particle- lter based estimation method is developed for the stochastic volatility model with/without jumps and … volatility option pricing models with a constant elasticity of variance, and can allow for price jumps. Our contention is that … using the VIX term structure in estimation can help us reach a more reliable conclusion in terms of the nature of the risk …
