A Chartered Financial 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 the relationship between the risk and the expected return on an investment and that is used in the pricing of risky securities. The assumption behind the CAPM is that there is only one risk-free rate in the model, investors can borrow and lend unlimited amounts under the risk rate of interest; the perfect information is freely available to all investors who, as a result, have the same expectations; that all investors are risk averse, rational and desire to maximise their own utility; and the capital market is characterised by perfect competition, there are broadly diversified across a range of investments and the investors will only require a return for the systematic risk of their portfolio, since unsystematic risk has been removed and can ignored. It also assumes all investors choose their portfolio according to the mean-variance criterion which ignores practical considerations such as trade without transaction or taxation costs. Under these assumptions, the market portfolio lies on the efficient frontier. The CAPM is represented as: E(Ri) = Rf + βi [E(RM)- Rf] The CAPM is remarkable because it tell us what should be the expected or required rates of return on all risky assets. The Security Market Line (SML) represents this relationship. Where E(Ri) is the appropriate expected rate of return on securities or portfolio I, Rf is the risk-free rate, E(RM) is the expected return on the market, and βi (beta) is the sensitivity of the...

...CAPITALASSETPRICINGMODEL
The CAPM says that the expected return of a security or a portfolio equals the rate on a risk-free security plus a risk [pic]premium. If this expected return does not meet or beat the required return, then the investment should not be undertaken. The security market line plots the results of the CAPM for all different risks (betas).
Using the CAPM model and the following assumptions, we can...

Undiversifiable (market )risk:
Market risk is the variability in all risky assets caused by macroeconomic variables. This risk cannot be avoided, regardless of the amount of diversification. Systematic risk (Market risk) factors are those macroeconomic variables that affect the valuation of all risky assets such as variability in the growth of the money supply, interest rate volatility, variability in...

...CapitalAssetPricingModel (CAPM): Pros and Cons.
CAPM defines the relationship between risk and return. The premise of the model is that the expected investment return varies in direct proportion to its risk, i.e., the riskier the investment - the higher the return you should expect.

• how much risk you are taking when investing in an instrument?
• whether the instrument is rightly priced
• whether you are...

...CAPITALASSETPRICINGMODEL (CAPM) The capitalassetpricingmodel (CAPM) is an important model in finance theory. CAPM is a theory or model use to calculate the risk and expected return rate of an investment portfolio (normally refer to stocks or shares). All stocks have 2 risks: Systematic Risk (also called Market Risk which...

...(section B)): The CapitalAssetPricingModel holds in economies satisfying a certain set of conditions. State four of these conditions and identify why they are essential for the model to hold (you are not expected to derive the entire model but you must identify the steps in the theory where these conditions play an important role).
Under 7 sets of key assumptions, we know that all agents will...
