CAPM and APT have emerged as two famous models that have tried to scientifically measure the potential for assets to generate a positive or negative return. Both of them are based on the efficient market hypothesis, and are part of the modern portfolio theory.

We show whatmake them successful for the pricing of assets. Indeed, the drawbackand limitations of these models will be addressed as : Capital asset pricing model , Arbitrage pricing The-ory, asset IntroductionBased on the pioneering work of Markowitz and Tobin for riskyassets in a portfolio, Sharpe , Lintner and Mossin deriveda general equilibrium model for the pricing of assets under uncertainty, calledthe Capital asset pricing model CAPM. This task iscentral to many financial decisions such as those relating to portfolio opti-mization, Capital budgeting, and performance evaluation. The measure ofrisk in the CAPM is given by the security s covariance with the market port-folio, the so-called market , the CAPM quantifies the expected rates of return of an asset withits relative level of market systematic risk beta.
This theory, like CAPM , provides investors with an estimated required rate of return on risky securities. APT considers risk premium basis specified set of factors in addition to the correlation of the price of the asset with expected excess return on the market portfolio. As per assumptions under Arbitrage Pricing Theory, return on an asset is dependent on various macroeconomic factors like inflation , exchange rates, market indices, production measures, market sentiments, changes in interest rates, movement of yield curves etc. The Arbitrage pricing theory based model aims to do away with the limitations of the one-factor model CAPM that different stocks will have different sensitivities to different market factors which may be totally different from any other stock under observation. In layman terms, one can say that not all stocks can be assumed to react to single and same parameter always and hence the need to take multifactor and their sensitivities. Most commonly used in U. Treasury bills for the U.
Show all documents Arbitrage pricing theory: evidence from an emerging stock market The development of financial equilibrium asset pricing models has been the most important area of research in modern financial theory. These models are extensively tested for developed markets. Explanatory factor analysis approach indicates two factors governing stock return. Pre-specified macro economic approach identifies these two factors as the anticipated and unanticipated inflation and market index and dividend yield. Some evidence of instability is found.
Both the capital asset pricing model CAPM and the arbitrage pricing theory APT are methods used to determine the theoretical rate of return on an asset or portfolio, but the difference between APT and CAPM lies in the factors used to determine these theoretical rates of return. CAPM only looks at the sensitivity of the asset as related to changes in the market, whereas APT looks at many factors that can be divided into either macroeconomic factors or those that are company specific. The capital asset pricing model was created in the s by Jack Treynor, William F.
In finance , the capital asset pricing model CAPM is a model used to determine a theoretically appropriate required rate of return of an asset , to make decisions about adding assets to a well-diversified portfolio. CAPM assumes a particular form of utility functions in which only first and second moments matter, that is risk is measured by variance, for example a quadratic utility or alternatively asset returns whose probability distributions are completely described by the first two moments for example, the normal distribution and zero transaction costs necessary for diversification to get rid of all idiosyncratic risk. Under these conditions, CAPM shows that the cost of equity capital is determined only by beta.
In finance , arbitrage pricing theory APT is a general theory of asset pricing that holds that the expected return of a financial asset can be modeled as a linear function of various factors or theoretical market indices, where sensitivity to changes in each factor is represented by a factor-specific beta coefficient. The model-derived rate of return will then be used to price the asset correctly—the asset price should equal the expected end of period price discounted at the rate implied by the model.
А теперь, если не возражаешь… - Стратмор не договорил, но Чатрукьян понял его без слов. Ему предложили исчезнуть. - Диагностика, черт меня дери! - бормотал Чатрукьян, направляясь в свою лабораторию. - Что же это за цикличная функция, над которой три миллиона процессоров бьются уже шестнадцать часов.
Конечно. Алгоритм, не подающийся грубой силе, никогда не устареет, какими бы мощными ни стали компьютеры, взламывающие шифры. Когда-нибудь он станет мировым стандартом.
Больно. - Да нет вообще-то. Я грохнулся на землю - такова цена, которую приходится платить добрым самаритянам.
- Чем же отличаются эти чертовы изотопы.
