Q

When combining asset classes, an investor begins to receive diversification benefits when correlation is

A

Less than 1

22
Q

Beta Coefficient is a measure of

A

an individual security’s volatility relative to that of the market

Measure of systematic/market risk

23
Q

Beta is best used to measure

A

the volatility of a diversified portfolio

the Beta of the market is 1

24
Q

A stock with a beta HIGHER THAN 1

A

Means the stock fluctuates more than the market and greater risk is associated

25
Q

A stock with a beta LOWER THAN 1

A

Indicates that the security fluctuates less relative to market movements

26
Q

If a fund has a return of 20% and the market has a return of 10%, the beta would be:

A

2

Security risk premium / Market risk premium

27
Q

Coefficient of DETERMINATIONS (R-Squared) is a measure of

A

How much return is due to the market

OR

What percentage of a security’s return is due to the market

28
Q

Market (systematic) Risk

A

Return from the market

Lowest level of risk one could expect in a fully diversified portfolio

Non-diversifiable

Economy-based risk

29
Q

Unsystematic Risk

A

Risks that are not shared with a wider market or industry (specific to a company/investment)

30
Q

Portfolio risk can be measured through

A

determination of the interactivity of the standard deviation and the covariance of securities in the portfolio

31
Q

Systematic Risks: P-R-I-M-E

A

Purchasing Power Risk
Reinvestment Rate risk (bonds)
Interest Rate Risk
Market Risk
Exchange Rate Risk

32
Q

Unsystematic Risks: A-B-C-D-E-F-G

A

Accounting risk
Business risk
Country risk
Default risk
Executive risk
Financial risk
Government/regulation risk

33
Q

Modern Portfolio Theory

A

The acceptance by an investor of a given level of risk while maximizing return objectives

34
Q

Modern Portfolio Theory: EFFICIENT FRONTIER

A

The curve which illustrates the best possible returns that could be expected from all possible portfolios

35
Q

Modern Portfolio Theory: INDIFFERENCE CURVES

A

Constructed using selections made based on this highest level of return given an acceptable level of risk

36
Q

Modern Portfolio Theory: EFFICIENT PORTFOLIO

A

Occurs when an investor’s indifference curve is tangent to the efficient frontier

37
Q

Modern Portfolio Theory: OPTIMAL PORTFOLIO

A

the one selected from all efficient portfolios

the point at which an investor’s indifference curve is tangent to the efficient frontier, represents that investor’s optimal portfolio

38
Q

Capital Market Line (CML)

A

the macro aspect of the Capital Asset Pricing Model (CAPM)

a portfolio’s return should be on the CML

39
Q

What measure of risk does the Capital Market Line (CML) use?

A

Standard deviation

40
Q

Capital Asset Pricing Model (CAPM) calculates

A

the relationship of risk and return of an individual security using BETA as it’s measure of risk

“Security Market Line” SML

41
Q

SML uses what as its measure of risk?

A

Beta

42
Q

What is the intersection on the y-axis of CML/SML

A

The risk-free rate of return

43
Q

Information Ratio

A

Relative risk-adjusted performance measure

The higher, the better

44
Q

Treynor Index

A

NUMERATOR: the difference between the portfolio return and risk-free return

DENOMINATOR: Beta of a portfolio

RISK-ADJUSTED performance measure

45
Q

Sharpe Index

A

Provides a measure of portfolio performance using a risk-adjusted measure that standardizes returns for their variability

NUMERATOR: the difference between the portfolio return and risk-free return

DENOMINATOR: Standard deviation of a portfolio

RISK-ADJUSTED performance measure

Better for NON-diversified portfolios

46
Q

Jensen Model or Jensen’s Alpha measures

A

a manager’s performance relative to that of the market

Can determine differences between realized or actual returns and required returns as specified by CAPM

ABSOLUTE PERFORMANCE on a risk-adjusted basis

positive Alpha is good
negative is BAD

47
Q

A portfolio is considered diversified if its R-squared is greater than

A

0.70

Any less = not well diversified (use Sharpe Index as measure)

REMEMBER! If correlation is 0.80, r-squared is 64%

48
Q

If the exam doesn’t give you the R-squared, which performance measure should you use?

A

Sharpe Index

49
Q

Total Risk = Systematic = Unsystematic Risk

Total risk is measured using ______

Systematic risk is measured using ______

A

Total Risk = Systematic = Unsystematic Risk

Total risk is measured using STANDARD DEVIATION

Systematic risk is measured using BETA

50
Q

The Beta of the Market is ____

A

1.0

51
Q

A stock that has a Beta of 1.5 is riskier or less risky than the market?

A

Riskier

52
Q

R-squared tells us what about Beta?

A

R-Squared will give us insight as to whether or not Beta is an appropriate measure of risk

If R-Squared is greater than .7 then YES, it is a good measure to use to assess RISK
