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 ...

Pointwise Arbitrage Pricing Theory in Discrete Time [PDF]
We develop a robust framework for pricing and hedging of derivative securities in discrete-time financial markets. We consider markets with both dynamically and statically traded assets and make minimal measurability assumptions. We obtain abstract (pointwise) fundamental theorem of asset pricing and pricing–hedging duality.

Scope of the arbitrage pricing theory [PDF]
An important element of the positive portfolio theory which in addition to the Capital Asset Pricing Model (CAPM) provides an important contribution in terms of understanding the relationship between return and risk and pricing of assets in the capital ...

Research on Amazon's stock price forecasting based on arbitrage pricing model based on big data
The generation of big data is based on the network data generated when people use Internet information systems to interact. Big data can reflect the general laws of specific fields and industries, provide more accurate references for decision makers and ...

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 ...

Empirical Test of the Arbitrage Pricing Theory Based on the Downside Risk(D-APT) in the Tehran Stock Exchange [PDF]
Extended Abstract Arbitrage pricing theory presented by Ross is based on theory of the absence of arbitrage opportunities in financial market and its main condition is the existence of a linear relationship between the actual return and a set of common ...

Coherent-Price Systems and Uncertainty-Neutral Valuation
This paper considers fundamental questions of arbitrage pricing that arises when the uncertainty model incorporates ambiguity about risk. This additional ambiguity motivates a new principle of risk- and ambiguity-neutral valuation as an extension of the ...

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 ...

Liquidity risk and arbitrage pricing theory [PDF]
The purpose of this paper is to develop a model for the inclusion of liquidity risk into arbitrage pricing theory that incorporates the impact of differing trade sizes on the price. The approach is consistent with price inelasticities. It is done by hypothesizing the existence of stochastic supply curve for a security price as a function of a trade ...
