The k factors are assumed to capture systematic risk common to all assets. They have homogeneous expectations about asset returns over the same one-period time horizon.
The realized returns Ri differ from their expected value E Ri by unexpected returns from pervasive factors weighted by their sensitivities and an unexpected residual return. This means that long positions in an arbitrage portfolio are exactly financed by short positions.
A risk-free asset offers, by definition, a rate of return which is certain variance of zero. The random ex post return of the i th asset is generated by the k -factor equation: Its fundamental intuition is the absence of arbitrage which is, indeed, central to finance and which has been used in virtually all areas of financial study.
The intuition of the pricing formula and its consistency with the state space preference theory are discussed. W n is the variance-covariance matrix of the noise terms E.
Ross b showed that either a risk-free asset or no restrictions on short sales are required for the CAPM. See Rossp. In general terms, the first applies to an exchange economy, the latter to a commerce economy including production.
There is a risk-free rate rf at which investors can lend or borrow money. Investors are risk averse, nonsatiated and act as price takers in competitive markets.
The relative market value of securities is simply equal to the aggregate market value of the security divided by the sum of the aggregated market values of all securities.
See also Reisman; Shanken It seems that the last word has not yet been spoken. The concept of efficient portfolios is due to Markowitz Expectations and risk aversion are bounded.
Therefore, unsystematic risk can be represented by a diagonal variance matrix. It is assumed that ex post returns of n risky assets are generated by a model of the form linear multiple regression: Only by introducing market imperfections, such as restrictions on short sales or informational inefficiencies, arbitrage opportunities might become apparent to a certain extent.
The Arbitrage Pricing Theory 3. He argued that the CAPM implies the mean-variance efficiency of the market portfolio. As can be seen in E. Nevertheless, it is possible to view the CAPM as a special case of APT with a single factor structure where the market portfolio is a proxy for the single factor.
The law of one price is an immediate implication of the absence of arbitrage without being equivalent. A rigorous analysis and proof of the APT were elaborated in Rossb. By definition, two vectors of the same order are orthogonal, when the inner product is zero.
And as long as it is limited the CAPM is not empirically testable. Accordingly, intertemporal analysis can be approached by two different models. Financial markets are frictionless. A non-linear pricing relation will be the consequence. For a discussion of these assumptions see Ross c.
The market model, mentioned earlier, is a one-factor model which assumes that asset returns are sensitive to only a single factor, namely the return on a market index. Factor models implicitly assume that the returns of securities are commonly correlated to the factors specified in the model.
Finally, n must be much greater than k E. It is indeed an appropriate and testable alternative to the CAPM. The arbitrage theory of asset pricing will be inquired in the following section. The market model  is usually used as the statistical return generating process in a CAPM context. See Rollp.
Information is freely and simultaneously available to all investors. In market equilibrium, the CAPM states a linear relationship between expected return and systematic risk: In a CAPM framework the factor is usually a market index.Master Thesis MSc.
