This study investigates the informational role of options trading in the price discovery process around the dissemination of accounting information, specifically annual and quarterly earnings announcements. Firstly, we examine the effect of options markets by analyzing stock market reaction to...

We investigate the effects of return jumps on option bid-ask spreads measured in implied volatility. To explain bid-ask spread quoting behavior, we construct a general model with market makers trading in an incomplete market in which a Bernoulli-type jump could occur. Following a numerical...

Money is not everything in life but money is the most important need of everyone's life. This paper describes the value of money which changed over a period of time. It also explain the important factor i.e. interest, due to which the value of money changes. This paper also discussed the...

We propose a modelling treatment for the option-implied risk neutral distribution (RND) which disaggregates its long-term and short-term dynamics. Long memory parameters calibrated on the RND moments serve as tractable mathematical constructs to filter out effects of smooth structural change...

A State Price Density (SPD) is the density function of a risk neutral equivalent martingale measure for option pricing, and is indispensible for exotic option pricing and portfolio risk management. Many approaches have been proposed in the last two decades to calibrate a SPD using financial...

Stocks with high idiosyncratic volatility perform poorly relative to low idiosyncratic volatility stocks. We offer a novel explanation of this anomaly based on real options, which is consistent with earlier findings on idiosyncratic volatility (the positive contemporaneous relation between...

Buy-Write and Put-Write strategies have been shown to match market returns with lower volatility resulting in higher risk-adjusted performance. The strategies benefit from the fact that implied volatility of options is generally higher than actual realized volatility. In this paper we show that...

In this paper, we combine modern portfolio theory and option pricing theory so that a trader who takes a position in a European option contract and the underlying assets can construct an optimal portfolio such that at the moment of the contract's maturity the contract is perfectly hedged. We...

The change of information near light speed, advances in high-speed trading, spatial arbitrage strategies and foreseen space exploration, suggest the need to consider the effects of the theory of relativity in finance models. Time and space, under certain circumstances, are not dissociated and...
