A note on arbitrage, approximate arbitrage and the fundamental theorem of asset pricing
نویسنده
چکیده
We provide a critical analysis of the proof of the fundamental theorem of asset pricing given in the paper Arbitrage and approximate arbitrage: the fundamental theorem of asset pricing by B. Wong and C.C. Heyde (Stochastics, 2010) in the context of incomplete Itô-process models. We show that their approach can only work in the known case of a complete nancial market model and give an explicit counterexample.

The Fundamental Theorem of Asset Pricing with either Frictionless or Frictional Security Markets
This paper studies asset pricing in arbitrage-free financial markets in general state space (both for frictionless market and for market with transaction cost). The mathematical formulation is based on a locally convex topological space for weakly arbitrage-free securities’ structure and a separable Banach space for strictly arbitragefree securities’ structure. We establish, for these two types...
متن کاملA Note on the Fundamental Theorem of Asset Pricing under Model Uncertainty
We show that the recent results on the Fundamental Theorem of Asset Pricing and the super-hedging theorem in the context of model uncertainty can be extended to the case in which the options available for static hedging (hedging options) are quoted with bid-ask spreads. In this set-up, we need to work with the notion of robust no-arbitrage which turns out to be equivalent to no-arbitrage under ...
متن کاملThe Second Fundamental Theorem of Asset Pricing: A New Approach
This article presents a new definition of market completeness that is independent of the notions of no arbitrage and equivalent martingale measures. Our definition has many advantages, all shown herein. First, it preserves the Second Fundamental Theorem of Asset Pricing, even in complex economies. Second, under our definition, the market can be complete yet arbitrage opportunities exist. This i...
متن کاملSimple Arbitrage Theory
In this paper we treat, under fairly general conditions, the question of whether asset prices admit a martingale measure when the markets are free of arbitrage opportunities. The arbitrage opportunities we consider are restricted to originate from simple trading strategies, which are most closely related to actual market portfolios. It is shown that if such simple arbitrage profits are excluded...
متن کاملArbitrage: Historical Perspectives
The concept of arbitrage has acquired a precise, technical meaning in quantitative finance (see Arbitrage Pricing Theory; Arbitrage Strategy; Arbitrage Bounds). In theoretical pricing of derivative securities, an arbitrage is a riskless trading strategy that generates a positive profit with no net investment of funds. This definition can be loosened to allow the positive profit to be nonnegativ...
