The aim of this paper is twofold: to investigate how the information content of implied volatility varies according to … moneyness and option type and to compare option-based forecasts with historical volatility. The different information content of … implied volatility is examined for the most liquid at-the-money and out-of-the-money options: put (call) options for strikes …

A stochastic model for pure-jump diffusion (the compound renewal process) can be used as a zero-order approximation and as a phenomenological description of tick-by-tick price fluctuations. This leads to an exact and explicit general formula for the martingale price of a European call option. A...

Inspired by the theory of social imitation (Weidlich 1970) and its adaptation to financial markets by the Coherent Market Hypothesis (Vaga 1990), we present a behavioral model of stock prices that supports the overreaction hypothesis. Using our dynamic stock price model, we develop a two factor...
