1. For each of the scenarios below, explain whether or not it represents a diversifiable or an undiversifiable risk. Please consider the issues from the viewpoint of investors. Explain your reasoning

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 aggregate industrial production, and natural shocks like drought, earth quake, hurricane, etc.

Diversifiable (unique )risk:
Many of the risks faced by an individual company are peculiar to its activity, its management, etc. These are the unique risks and can be diversified away. Examples of unique risks are a company winning a large contract, wildcat strikes hitting a company, litigation hitting a company or the company facing a governmental investigation.

a. A large fire severely damages three major U.S. cities.

Diversifiable risk
The entire economy will not be affected by a large fire in three major US cities. In fact some companies in cities not affected by fire will benefit as they will meet the demand not being met by companies in the three cities that are affected by the fire.

b. A substantial unexpected rise in the price of oil.

Undiversifiable risk
A substantial unexpected rise in the price of oil will increase the inflation rate that will affect the entire economy and all the companies
c. The bridge on a major highway collapsed and the repairs of the bridge may take up to a year to complete.

Diversifiable risk
The entire economy will not be affected; in fact some companies in areas not...

For assetpricing, the concepts of risk and return, and state prices will be introduced as a stepping stone towards the discussions of more advanced topics including the CapitalAssetPricingModel (CAPM), the Arbitrage Pricing Theory (APT), and other more recent assetpricingmodels. Other topics in finance such as options and behavior finance may also be covered on an optional basis. Besides the theoretical frameworks, recent developments in empirical assetpricing and empirical finance will also be covered with an extensive use of academic research papers.

...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 affect every stocks) and Unsystematic Risk (also called Specific or Unique Risk that only affects individual stocks). To diversify unsystematic risk, we selected and combined different stocks, which are negatively correlated with one another into one portfolio. In this way risk are eliminated greatly. See diagram below.
CAPM Equation The general formula used for CapitalAssetPricingModel is: re = rf + [ ß (rm - rf) ] where the components are as follows: re = Expected return rate of the investment portfolio rf = Risk free rate of return ß = Beta (correlation between the shares and the market) rm = Expected market return which also means: rm - rf = Market risk (systematic risk) ß (rm - rf) = Risk premium *Beta is overall risk value for investing in the stock market. The higher the beta, the more the risk.
CAPM Example Assume there is two Investment portfolio (stocks) or project - A & B. With the information given below, we can use CAPM to help us...

...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.
Shows:
• how much risk you are taking when investing in an instrument?
• whether the instrument is rightly priced
• whether you are getting sufficient return for the risk you are taking
CAPM calculates the risk-adjusted discount rate with the risk-free rate, the market risk premium, and beta (mathematical formula):
Return (R) = Rf + beta x (Rm - Rf)
Rf is the rate of risk-free investments
Beta - the risk of loss associated with your investments.
Rm is the expected market return.
(Rm-Rf) – market risk premium
beta x (Rm - Rf) – risk premium of specific company
Investments are good if the expected return from the investment equals/exceeds required return.
Market Risk Premium [Rm-Rf]
The additional return over the risk-free rate needed to compensate investors for assuming an average amount of risk
Its size depends on the perceived risk of the overall stock market and investors’ degree of risk aversion
Varies across time. Usually ranged between 4-8%
BETA in CAPM measures a stock’s degree of systematic or market risk. It can also be thought of as the stock’s contribution to the risk of a...

...A Chartered Financial Analyst, Jeffrey Bruner, uses the CapitalAssetPricingModel (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 CapitalAssetPricingModel (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...

...CAPM: THEORY, ADVANTAGES, AND DISADVANTAGES
THE CAPITALASSETPRICINGMODEL RELEVANT TO ACCA QUALIFICATION PAPER F9
Section F of the Study Guide for Paper F9 contains several references to the capitalassetpricingmodel (CAPM). This article is the last in a series of three, and looks at the theory, advantages, and disadvantages of the CAPM. The first article, published in the January 2008 issue of student accountant introduced the CAPM and its components, showed how the model can be used to estimate the cost of equity, and introduced the asset beta formula. The second article, published in the April 2008 issue, looked at applying the CAPM to calculate a project-specific discount rate to use in investment appraisal.
CAPM FORMULA The linear relationship between the return required on an investment (whether in stock market securities or in business operations) and its systematic risk is represented by the CAPM formula, which is given in the Paper F9 Formulae Sheet: E(ri) = Rf + βi(E(rm) - Rf) E(ri) = return required on financial asset i Rf = risk-free rate of return βi = beta value for financial asset i E(rm) = average return on the capital market The CAPM is an important area of financial management. In fact, it has even been suggested that finance only became ‘a fully-fledged, scientific...

...CapitalAssetPricingModelCapitalAssetPricingModel (CAPM)
Capital market theory extends portfolio theory and develops a model for pricing all risky assets. It is an equation that quantifies security risk and defines a risk/return relationship
Capitalassetpricingmodel (CAPM) will allow you to determine the required rate of return for any risky asset
Implications of the CAPM:
CAPM indicates what should be the expected or required rates of return on risky assets
This helps to value an asset by providing an appropriate discount rate to use in dividend valuation models
You can compare an estimated rate of return to the required rate of return implied by CAPM - over/under valued ?
Assumptions of the CAPM
1. All investors are Markowitz efficient investors who want to target points on the efficient frontier.
2. Investors can borrow or lend any amount of money at the risk-free rate of return
3. All investors have homogeneous expectations;
4. All investors have the same one-period time horizon such as one-month, six months, or one year
5. All investments are infinitely divisible, which means that it is possible to buy or sell fractional shares of any asset...

...CHAPTER 9
THE CAPITALASSETPRICINGMODEL
9.1 THE CAPITALASSETPRICINGMODEL
1. The CAPM and its Assumptions
The capitalassetpricingmodel (CAPM) is a set of predictions concerning equilibrium expected re¬turns on risky assets. Harry Markowitz laid down the foundation of modern portfolio man¬agement in 1952. The CAPM was developed 12 years later in articles by William Sharpe (1964), John Lintner (1965), and Jan Mossin (1966). The time for this gestation indicates that the leap from Markowitz's portfolio selection model to the CAPM is not trivial.
We summarize the simplifying assumptions that lead to the basic version of the CAPM in the following list. The trust of these assumptions is that we try to assure that individuals are as alike as possible, with the notable exceptions of initial wealth and risk aversion. We will see that conformity of investor behaviour vastly simplifies our analysis.
1. There are many investors, each with an endowment (wealth) that is small compared to the total endowment of all investors. Investors are price-takers, in that they act as though security prices are unaffected by their own trades. This is the usual perfect competition assumption of microeconomics.
2. All investors plan for one identical holding period. This behavior is...
