Intertemporal Arbitrage Pricing Theory [PDF]
It is shown that the arbitrage pricing theory holds in each infinitesimal period of a continuous trading model under the assumption that dividend payoffs are functionals of factor and idiosyncratic uncertainty. This generalizes the one-period model's result that the arbitrage pricing theory holds under the assumption that price changes in a given ...

Risk-Neutral Pricing for Arbitrage Pricing Theory [PDF]
AbstractWe consider infinite-dimensional optimization problems motivated by the financial model called Arbitrage Pricing Theory. Using probabilistic and functional analytic tools, we provide a dual characterization of the superreplication cost. Then, we show the existence of optimal strategies for investors maximizing their expected utility and the ...

Stochastic arbitrage return and its implications for option pricing [PDF]
The purpose of this work is to explore the role that arbitrage opportunities play in pricing financial derivatives. We use a non-equilibrium model to set up a stochastic portfolio, and for the random arbitrage return, we choose a stationary ergodic ...

Semi-parametric Model of Idiosyncratic Volatility Pricing by Explaining the Arbitrage Risk [PDF]
Objective: The relationship between idiosyncratic volatility and expected return in finance has become a puzzle. While, based on modern portfolio theory, the relationship between risk and expected return is positive, many studies find a negative ...
