the purpose of this research is investigation of application of the arbitrage pricing theory and effect of unanticipated changes in a set of macroeconomic variables such as inflation rate, money supply, exchange rate, oil price, term structure and industrial production on expected security return in tehran stock exchange. in this research, data are analyzed quarterly for the period of 1997-2008...

in this paper, installment options on the underlying assetwhich evolves according to black-scholes model and pays constant dividendto its owner will be considered. applying arbitrage pricing theory,the non-homogeneous parabolic partial differential equation governingthe value of installment option is derived. then, penalty method is usedto value the european continuous installment call option.

The main objective of this study is to give the insight of describing mixing accounting ratios and macroeconomic variables as the risk factors in Iran. The results indicate a significant relationship between book to market ratio, financial leverage, size factors and expected stock returns in the Iranian market. In consistent with the other studies, we came to the conclusion that the term struct...

In this paper, installment options on the underlying asset which evolves according to Black-Scholes model and pays constant dividend to its owner will be considered. Applying arbitrage pricing theory, the non-homogeneous parabolic partial differential equation governing the value of installment option is derived. Then, penalty method is used to value the European continuous installment call opt...

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...

We provide a detailed portfolio analysis for a nancial market with an atomless continuum of assets. In the context of an exact arbitrage pricing theory (EAPT), we go beyond the characterization of the existence of important portfolios (normalized riskless, mean, cost, factor and mean-variance eÆcient portfolios) to furnish exact portfolio compositions in terms of explicit portfolio weights. Suc...

We generalize the Arbitrage Pricing Theory (APT) to include the contribution of virtual arbitrage opportunities. We model the arbitrage return by a stochastic process. The latter is incorporated in the APT framework to calculate the correction to the APT due to the virtual arbitrage opportunities. The resulting relations reduce to the APT for an infinitely fast market reaction or in the case wh...
