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. The most significant conceptual difference between the arbitrage pricing theory (apt) and the capital asset pricing model (capm) is that the capm _____________ a places less emphasis on market risk. There are inherent risks in holding any asset, and the capital asset pricing model (capm) and the arbitrage pricing model (apm) are both ways of calculating the cost of an asset and the rate of return which can be expected based on the risk level inherent in the asset (krause, 2001.
The capital asset pricing model is an equilibrium model that measures the relationship between risk and expected return of an asset based on the asset’s sensitivity to movements in the overall stock market. The arbitrage model was proposed as an alternative to the mean variance capital asset pricing model, introduced by sharpe, lintner, and treynor, that has become the major analytic tool for explaining phenomena observed in capital markets for risky assets. A major alternative to the capital asset pricing model (capm) is arbitrage pricing theory (apt) proposed by ross in 1976 arbitrage pricing theory as opposed to capm is a multifactor model suggesting that expected return of an asset cannot be measured accurately by taking into account only one factor, ie the asset beta.

The capital asset pricing model (capm) is a special case of the arbitrage pricing model (apt) in that capm uses a single factor (beta as sensitivity to market price changes) whereas the apt has multiple factors which may not include the capm beta. Arbitrage pricing theory (apt) is an alternate version of capital asset pricing model (capm)this theory, like capm provides investors with 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. This is the capital asset pricing model (capm) the expected return on a risky asset thus has three components the first is the pure time value of money (rf), the second is the market risk premium, [e(rm) - rf], and the third is the beta for that asset, bi. Both the capital asset pricing model and the arbitrage pricing model rest on the assumption that investors are reward with non-zero return for undertaking two activities: (1) committing capital (non-zero investment) and (2) taking risk. The capital asset pricing model and arbitrage pricing theory introduction better asset pricing models are some of the most researched topics in finance, with broad applications in risk management, asset allocation, and market valuations.
The arbitrage pricing theory (apt) was developed primarily by ross (1976a, 1976b) it is a one-period model in which every investor believes that the stochastic properties of returns of capital assets are consistent with a factor structure. Focusing on capital asset returns governed by a factor structure, the arbitrage pricing theory (apt) is a one-period model, in which preclusion of arbitrage over static portfolios of these assets leads to a linear relation between the expected return and its covariance with.
