Q

The benefits of diversification decline to near zero when the number of securities held increases beyond:

A: 40

B: 10

C: 6

D: 4

A

A. 40

In practice, the benefits of diversificaiton become extremely small when more than about 20 to 30 different securities are held.

Q

What is the CAPM equation?

What does it measure?

A

Capital Asset Pricing Model

  • Measures how a particular security contributes to the risk and return of a diversified portfolio
  • Quantifies the required return on an equity security by relating the security’s level of risk to the average return available in the market
  • Based on time value of money and risk

Q

What are the two basic types of investment risk?

Describe each…

A

Systematic Risk (market risk) - risk faced by all firms; also undiversifiable risk

Unsystematic Risk (company risk) - risk inherent in a particular investment security; also diversifiable risk

Q

What is the coefficient of variation?

When is it useful?

What is the formula = ?

A

The coefficient of variation (CV) measures the risk per unit of return

Useful when the rates of return and standard deviations of two investments differ

*the lower the ratio, the better the risk-return tradeoff is

Q

What is covariance?

What is the formula = ?

A

A measure of two stocks’ mutual volatility

17
Q

What is specific risk?

A

Risk associated with a specific investee’s operations: new products, patents, acquisitions, competitors’ activites, etc.

This can be potentially elimiated by diversification

Also called: diversifiable risk, unsystematic risk, residual risk, and unique risk

18
Q

What is market risk?

A

The risk of the stock market as a whole

Also called undiversifiable risk and systematic risk

19
Q

What is a beta coefficient?

A

A stock’s sensitivity to movements by the overall market.

Average risk stock: beta = 1.0; its returns are perfectly positively correlated with the market portfolio

Beta < 1.0: security less volatile than the market

Beta > 1.0: indicates a volatile security

If return increases 30% when the market return increases by 15%, security has a beta of 2.0

20
Q
  1. How else may the beta for a security be calculated?
  2. What is the beta of a portolio equal to?
A
  1. May be calculated by dividing the covariance of the return on the market and the return on the security by the variance of the return on the market
  2. Beta of a portfolio is the weighted average of the betas of the individual securities
21
Q

Draw the CAPM formula using:

Market Rate

Risk-free rate

Show Market risk premium

Show Risk free premium

Security market line

A
22
Q

List two practical probelms with the use of CAPM

A
  1. It is hard to estimate the risk-free rate of return on projects under different economic environments
  2. The CAPM is a single-period model. It should not be use dfor projects lasting more than 1 year
23
Q

What is the difference between the CAPM model and the APT model?

A

CAPM: a model that uses just one systematic risk factor to explain the asset’s return

APT: an asset’s return is a function of multiple systematic risk factors

  • APT provides for a separate beta and a separate risk premium for each systematic risk factor in the model
24
Q

What is the equation for APT?

A

i.e. 3-factor model

Advantage: APT can provide more exact information.

Disadvantage: APT is potentially more difficult to calculate

25
Q

What is the Fama-French 3-factor model?

What is the equation?

A

An alternative to CAPM

Recognizes that two classes of stocks typically perform better than the stock market as a whole

  1. Small-cap stocks
  2. Stocks with high book-to-market ratio (value stocks)
26
Q

What are two types of risk related to financial risk?

A
  1. Business risk: risk of an adverse outcome based on a change in the firms particular context (e.g. changes in input prices, consumer tastes, regulator environments)
  2. Financial risk: risk of an adverse outcome based on a change in the financial markets (e.g. changes in interest rates, investors’ desired rates of return)
27
Q

A firm with high operating leverage carries a greater degree of risk because fixed costs must be covered regardless of the level of sales.

However, a firm is also able to expand production rapidly in times of higher product demand.

“operating leverage sensitivity”

A
28
Q

The degree of a firm’s financial leverage increases as it uses more fixed costs (i.e. debt and preferred stock) in its financial structure

“financial leverage sensitivity”

A
29
Q

What does the indifference curve measure?

A

The indifference curve represents combinations of portfolios having equal utility to the investor.

The steeper the slope of an indifference curve, the more risk averse an investor is

The higher the curve, the greater is the investor’s level of utility

30
Q

What are two important decisions involved in managing a company’s portfolio?

A
  1. The amount of money to invest
  2. The securities in which to invest
31
Q

What is hedging?

A

The process of using offsetting commitments to minimize or avoid the impact of adverse price movements.

  • The purchase or sale of of a derivative is a hedge if it is expected to neutralize the risk of a recognized asset or liability, an unrecognized firm commitment, a forecasted transaction, etc.
32
Q
  1. What are long hedges?
  2. What are short hedges?
  3. What is a natural hedge?
A
  1. Futures contracts that are purchased to protect against price increases
  2. Futures contracts that are sold to protect against price declines
  3. A method of reducing financial risk by investing in two different items whose performance tends to cancel each other out.
33
Q
  1. What is duration hedging?
  2. What is the goal of duration hedging?
A
  1. Involves hedging interest rate risk.
  2. The goal of duration hedging is not to equate the duration of assets and duration of liabilities but for the following relationship to apply.

If the duration is positive, company exposed to rising interest rates

If the duration is negative, company exposed to falling interest rates
