It builds on the assumptions of the MPT.<\/p>\n<p>CAPM gives a linear expected return-beta relationship that determines the expected return given a beta of an asset. Thus CAPM provides a transition from the total risk (a used in CML) to systematic risk as to the primary determinant of expected return. CAPM is usually implemented through the security market line (discussed later).<\/p>\n<p>The general expectation in a competitive market is that if securities\/investments have the same level of risk, they should have the same level of expected return.<\/p>\n<h3>Assumptions of the Capital Asset Pricing Model<\/h3>\n<p>The extra assumptions introduced by CAPM include:<\/p>\n<ul>\n<li>A risk-free rate exists in the market, and investors can borrow and lend unlimited amounts at this rate.<\/li>\n<li>The markets for risky assets are perfect, meaning investors have access to all the information that can affect the price of a given security.<\/li>\n<li>Investors have the same estimates of the expected returns, standard deviations, and covariance over the one-period horizon.<\/li>\n<li>All investors have the same one-period horizon.<\/li>\n<li>All investors measure in the same &#8220;currency&#8221; for example dollars or in &#8220;real&#8221; or &#8220;money&#8221; terms.<\/li>\n<li>There are no transaction costs.<\/li>\n<li>There are no taxes.<\/li>\n<li>There is perfect divisibility of assets, i.e., assets can be bought and sold in very small quantities.<\/li>\n<li>All assets are marketable or liquid, i.e., investors can transact in large quantities with little or no impact on the price.<\/li>\n<li>Unlimited short-selling is permissible.<\/li>\n<li>Investors are price takers whose individual buy and sell decisions do not affect the price.<\/li>\n<li>Investors&#8217; utility functions are based solely on the expected portfolio return and risk.<\/li>\n<\/ul>\n<h3>Properties of Capital Asset Pricing Model<\/h3>\n<p>Investors will, in general, hold investments in both the risk-free assets and risky assets based on their own levels of risk aversion.<\/p>\n<p><strong>Investors have the same expectations about the rate of return on risky assets, variances of those returns, and their covariances: <\/strong>If this holds, then all investors will end up selecting the same portfolios from the efficient frontier of risky assets resulting in the market portfolio.<\/p>\n<p>The market portfolio will contain the portfolio of securities whose returns are sensitive to systematic risks.<\/p>\n<p><strong>Investors are subject to the same risk-free rate of return under CAPM: <\/strong>If this holds, then the tangent line to the efficient frontier of risky assets will intercept the y-axis at the risk-free rate of interest.<\/p>\n<h2>The Security Market Line<\/h2>\n<p>The security market line (SML) is a graphical representation of the capital asset pricing model where beta (reflecting the systematic risk) on the x-axis and the expected return on the y-axis.

Generally, investors in the real world will be subjected to different rates of lending and borrowing.<\/li>\n<li>CAPM assumes no taxes. In practice, investors will be subject to charges, such as the capital gains tax. If this is taken into account, then the expected return computed using CAPM may be underestimated.<\/li>\n<li>CAPM assumes that investors will select their portfolios from the market portfolio. In practice, investors will be open to a universe of opportunities to choose from and thus would not always select the said market portfolio.<\/li>\n<li>The expected returns of securities are based on historical performance, which may not reflect the future outcome.<\/li>\n<li>Assumptions of investor behavior like risk aversion may not hold in practice as normal markets will comprise investors with different risk appetites.<\/li>\n<\/ul>\n<h2>Factor Models<\/h2>\n<p>Factor models are financial models that incorporate different risk elements in the market to determine the expected return on an asset or security.<\/p>\n<p>These models incorporate macroeconomic, fundamental, and statistical factors to characterize the market and help calculate the required return on an asset or security.<\/p>\n<p>Below we describe macroeconomic, statistical, and fundamental factor models:<\/p>\n<p><strong>Macroeconomic factor models<\/strong> \u2013 These use observable historical time series factors such as interest rates, inflation, and economic growth in a bid to estimate the influence these factors may have on future returns of a portfolio or security.<\/p>\n<p><strong>Fundamental factor models<\/strong>&nbsp;\u2013&nbsp;These use company-specific variables to compare the sensitivity of a portfolio to one of the factors within the factors of a benchmark portfolio. Some of these fundamental factors would include the price-earnings ratio, the industry the company is operating in, etc.<\/p>\n<p><strong>Statistical factor models<\/strong>&nbsp;\u2013&nbsp;These make use of principal component analysis to determine as much as possible the set of factors or indices that explain as much as possible the relationship between the risk and return of a given portfolio.<\/p>\n<h3 data-tadv-p=\"keep\">Expected Return, Factors, Factor Betas, and Firm-Specific Components of a Security from its Factor Equation<\/h3>\n<p>A <strong>factor <\/strong>can be defined as a variable that explains the expected return of an asset.<\/p>\n<p>A <strong>factor-beta<\/strong> measures the sensitivity of the return on a given asset to a specific factor. The bigger the factor, the more sensitive the asset return is to that factor.<\/p>\n<p>Let &nbsp;denote a component-specific factor affecting the return of an asset<\/p>\n<p>Using a factor model, the required return of a stock return can be given as:<\/p>\n<p>$$R_i=a_1+\\beta_iF\\cdots+e_{i\\ }$$<\/p>\n<p>Where,<\/p>\n<p>\\(R_i\\)= rate of return on stock i<\/p>\n<p>\\(a\\) = The constant factor with relation to security i<\/p>\n<p>\\(\\beta_i\\)= sensitivity of the stock&#8217;s return to a one-unit change in factor F<\/p>\n<p>\\(e_i\\)= portion of the stock&#8217;s return unexplained by macro factors or, more generally, the error term. It usually has a mean of zero.<\/p>\n<p>The part \\(\\beta_i+F+e_i\\) of the formula above is called the systematic return of security \\(i\\). In contrast, the remaining factor is called the specific return, which is unique and independent of systematic return factors.<\/p>\n<p>The expected return on the stock can then be expressed as:<\/p>\n<p>$${E(R}_i)=E(a)+\\beta_iE(F)+{E(e}_{i\\ })=a+\\beta_iF$$<\/p>\n<p>The expected return from a factor model can thus be seen as a linear function of the security&#8217;s constant independent return and the sensitivity of the security returns to a specific factor.<\/p>\n<h2>Single-Factor and Multi-Factor Models<\/h2>\n<p>Suppose a factor model only incorporates one factor representing a single element of the systematic risk affecting the return on a security. In that case, the model will be said to be a <strong>single-factor model<\/strong>.<\/p>\n<p>Using the single-factor model, the required return on an asset is given as:<\/p>\n<p>$$R_i=a+\\beta_iF+e_{i\\ }$$<\/p>\n<p>The expected return on an asset using a single factor model can be expressed as:<\/p>\n<p>$${E(R}_i)=a+\\beta_iF$$<\/p>\n<p>The variable \\(a\\) here represents the constant independent return, \\(\\beta_i\\) the sensitivity of the returns in response to a change in the factor, and \\(F\\) the market premium in response to the factor.<\/p>\n<p>In this case, the systematic risk of the factor will equal the total risk of the asset.<\/p>\n<p>An example of a single index model is the CAPM, which limits the risk to one source, that is, the covariance with the market portfolio.<\/p>\n<p>If we combine more than one factor to construct our efficient portfolio, each factor will capture different elements of the systematic risk of the resulting asset return. Such a model is known as a <strong>multi-factor model.<\/strong><\/p>\n<p>Thus, a <strong>multi-factor model<\/strong> is a financial model that employs multiple factors in its calculations to explain asset prices. Such models introduce uncertainty stemming from multiple sources.<\/p>\n<p>Using the multi-factor model, the required return on an asset is given as:<\/p>\n<p>$${E(R}_i)=a+\\beta_iF_1+\\beta_2F_2+\\ldots+\\beta_nF_n+e$$<\/p>\n<p>The expected return on an asset using a multi-factor model can be expressed as:<\/p>\n<p>$${E(R}_i)=a+\\beta_iF_1+\\beta_2F_2+\\ldots+\\beta_nF_n$$<\/p>\n<p>Where \\(\\beta_i\\) represent the sensitivity of the asset returns to factor \\(F\\) and \\(F_i(i=1,2\\ldots n)\\) the market premium with respect to the factor \\(F\\).<\/p>\n<p>An example of a multi-factor model is the Arbitrage Pricing Theory<\/p>\n<h4>Example: Calculating the required Return of an Asset using the Single-factor Model<\/h4>\n<p>Assume the common stock of Blue Ray Limited (BRL) is examined with a single-factor model, using unexpected percent changes in GDP as the single factor.

It assumes a market in equilibrium but does not rely on strong assumptions of CAPM. Its basis is built from multifactor models and assumes that the investment environment is arbitrage-free.<\/p>\n<p>The APT theory describes expected returns as a linear function of exposures to common macroeconomic risk factors.<\/p>\n<p>$$E(R_i)=R_F+\\beta_{i1}RP_1+\\beta i2RP_2+\\beta_{i3}RP_3+\\cdots+\\beta_{iK}RP_K$$<\/p>\n<p>Where,<\/p>\n<p>\\(RP_j\\) = The excess return over the risk-free rate attached to a risk factor; and<\/p>\n<p>\\(\\beta_{i1}\\) = The sensitivity of the stock return to one unit change in factor \\(j\\).<\/p>\n<p>Expanding the above formula, we get the APT equation as follows:<\/p>\n<p>$$E\\left(R_i\\right)=R_F+\\beta_{i1}\\left[E\\left(R_1\\right)-R_F\\right]+\\beta_{i2}\\left[E\\left(R_2\\right)-R_F\\right]+\\beta_{i3}\\left[E\\left(R_3\\right)-R_F\\right]+\\cdots\\ \\ \\ \\ \\ $$$$+\\beta_{iK}[E(R_K)-R_F]$$<\/p>\n<h3>Assumptions of the APT Model<\/h3>\n<ul>\n<li>Well-diversified portfolios can be formed.<\/li>\n<li>No arbitrage opportunities exist.<\/li>\n<li>Returns follow a -factor process.<\/li>\n<\/ul>\n<p>The main strength of the APT approach is that it is based on the no-arbitrage investment world. However, it does not explain the best multifactor model and the size of the constants.<\/p>\n<h4>Example: Calculating the Expected Return using The Arbitrage Pricing Theory<\/h4>\n<p>The following data exists for asset A:<\/p>\n<ul>\n<li>Risk-free rate = 3%,<\/li>\n<li>GDP factor beta = 0.40,<\/li>\n<li>Consumer sentiment factor beta = 0.20,<\/li>\n<li>GDP risk premium = 2%,<\/li>\n<li>Consumer sentiment risk premium = 1%<\/li>\n<\/ul>\n<p>Calculate the expected return for Asset using a 2-factor APT model.<\/p>\n<p>$$E(R_A)=0.03+0.4(0.02)+0.2(0.01)=0.04=4\\%$$<\/p>\n<p><strong>Note<\/strong>: Both CAPM and APT describe equilibrium expected returns for assets.
