generating process‚ and that in well-functioning financial markets‚ there will be no arbitrage opportunities. On the basis of these assumptions‚ one can show that there is an equilibrium linear relationship between the returns on risky assets and a small set of economy-wide common factors. While several macroeconomic variables do have some relationship with different risky assets‚ the APT postulates that the pricing of risky assets depends only on the set of variables whose influence is felt significantly

ARBITRAGE PRICING THEORY ( APT ) Originally developed by Stephen A. Ross. The CAPM predicts that security rates of return will be linearly related to a single common factor : ----- the rate of return on the market portfolio. The APT is based on a similar approach but assumes the rate of return on a security to be sensitive to a number of factors. Market equilibrium is driven by individuals eliminating arbitrage

Arbitrage Pricing Theory The fundamental foundation for the arbitrage pricing theory is the law of one price‚ which states that 2 identical items will sell for the same price‚ for if they do not‚ then a riskless profit could be made by arbitrage—buying the item in the cheaper market then selling it in the more expensive market. This principle also applies to financial instruments‚ such as stocks and bonds. For instance‚ if Microsoft stock is selling for $30 on one exchange‚ but $30.25 on another

An Empirical Investigation of Arbitrage Pricing Theory: A case Zimbabwe Petros Jecheche University of Zimbabwe ABSTRACT This study investigates the Arbitrage Pricing Theory for the case of Zimbabwe using time series data from 1980 to 2005 within a vector autoregressive (VAR) framework. The Granger causality tests are conducted to establish the existence of causality among the variables like inflation‚ exchange rate and Gross Domestic Product. The VAR estimates as shown by the impulse response

Analyst‚ Jeffrey Bruner‚ uses the Capital Asset Pricing Model (CAPM) to help identify mispriced securities. However‚ a consultant suggests Bruner to use Arbitrage Pricing Theory (APT) instead. As the following‚ it will mention the role of CAPM in the modern portfolio management; to clarify the APT faction and explain the reasons why should Bruner use APT to help identify mispriced securities. In modern portfolio management‚ the role of Capital Asset Pricing Model (CAPM) is a model that attempts to describe

Compare and contrast CAPM and APT? Capital asset pricing model (CAPM) and arbitrage pricing theory (APT) are both methods of assessing an investment’s risk in relation to its potential reward and whether the potential investment yield is worthwhile. CAPM developed by Sharpe 1964. The basic theory behind this model is that investor needs to be compensated for Time Value of Money and the risk that they are taking. The time value of money is represented by the risk-free (rf) rate in
