FIN 334 Exam 3 Chapter 13
Correlation ranges from what to what?
-1 to +1
R-squared ranges from what to what?
0 to 100 percent
How is jensen's alpha interpreted?
A measure of by how much the portfolio "beat the market"
What does an R-squared of 100 indicate?
All movements in the security are driven by the market, indicating a correlation of -1 or +1
The information ratio also allows to compare investments with different what?
Alphas and tracking errors
Which things does the treynor ratio standardize?
Any excess return, relative to beta
If the returns on an investment follow a normal distribution, then we can state the probability that a portfolio's return will what?
Be within a certain range
In an active, competitive market, a strong argument can be made that all assets (and portfolios of these assets) should have the same treynor ratio, that is the same reward-to-risk ratio, where risk refers to systematic risk. To the extent that they don't, then there is evidence that at least some portfolios have what?
Earned excess returns
How do you determine if a fund's alpha is statistically significant from zero?
Evaluating the significance level of the alpha estimate that comes from the regression, or calculating the funds information ratio
What does the Jensen-Treynor alpha measure?
Excess return relative to beta, which is similar to the information ratio
Finding the sharpe-optimal portfolio boils down to what?
Finding the line with the steepest slope
Concerns a money manager's control over investment risks, usually with respect to potential short-run losses
Investment risk management
What does and does not the the Markowitz efficient frontier tell you?
It tells you which portfolios are efficient, but it does not tell you which of the efficient portfolios is the best
What is a strength of Jensen's alpha?
It's easy to interpret
If you took ____ and divide it by beta, then have a Jensen-Treynor alpha
Jensen's alpha
Which two performance measures are really very similar?
Jensen's alpha and the Treynor ratio
Taking jensen's alpha and dividing it by beta gives you what?
Jensen-Treynor alpha
What are advantages of the sharpe ratio?
No beta is necessary and standard deviations can be calculated unambiguously
Do all of the performance measures yield similar results?
No, not always
Are firms required to comply with GIPS? Explain.
No. Firms that do comply, though are recognized by the CFA institute which might give the firms more credibility among potential investors
A statistical model for assessing probabilities related to many phenomena, including security returns
Normal distribution
The assessment of how well a money manager achieves a balance between high returns and acceptable risks
Performance evaluation
The treynor ratio is a ___ ratio
Reward-to-risk
The sharpe ratio is a ____ ratio that focuses on ___ risk
Reward-to-risk; total
If you wish to select a performance measure to evaluate an entire portfolio held by an investor, the ___ ratio is appropriate
Sharpe
The ___ ratio is probably most appropriate for evaluating relatively diversified portfolios
Sharpe ratio
The treynor risk looks at ___ risk
Systematic risk only, not total risk
What does a relative measure mean?
That no absolute number represents a "good" or "bad" performance
A high r-squared value might suggest what?
That the performance measures (such as alpha) are more representative of potential longer-term performance
How is a measure of consistency implemented?
The CFA institute developed the Global Investment Performance Standards
How is jensen's alpha understood?
The excess return above or below the security market line
What does the slope of the characteristic line represent?
The investments beta
If two funds both have alphas of 1.5 percent which do you prefer, and why?
The one with the higher information ratio, because less risk, (or volatility) is associated with that fund
What does r-squared represent?
The percentage of the fund's movement that can be explained by the movements in the market
With relative measures, how is the performance evaluated then?
The ratios must be compared to those of other managers-or to a benchmark index
What does the characteristic line graph?
The relationship between the return of an investment (y axis) and the return of the market or benchmark (on the x axis)
How is the sortino ratio calculated?
The same way as the sharpe ratio, except you calculate the standard deviation using only returns that lie below the mean
Return standard deviation is a measure of what?
The total risk, (as opposed to systematic risk) for a security or a portfolio
What is a weakness of the jensen and treynor measures?
They both require a beta estimate, and betas from different sources can differ substantially
What is the purpose of the sortino ratio?
To penalize the investment manager for having undesirable volatility caused by negative excess returns
What is the purpose of the Global Investment Performance Standards?
To standardize the process to provide investors with the ability to make comparisons across managers
What is a drawback to the sharpe ratio?
Total risk is frequently not what really matters
The ___ ratio standardizes everything, including any excess return, relative to beta
Treynor
If you wish to choose a performance measure to individually evaluate securities or portfolios for possible inclusions in a broader, (or "master") portfolio, then with two performance measures are appropriate?
Treynor ratio or Jensen's alpha
In an active, competitive market, a strong argument can be made that all assets (and portfolios of these assets) should have the same ___ ratio, that is the same ___ ratio, where risk refers to ___ risk
Treynor ratio; reward-to-risk; systematic
Assesses risk by stating the probability of a loss a portfolio might experience within a fixed time horizon with a specified probability
Value-at-risk
Why is comparing investments sometimes difficult?
Various performance metrics can provide different rankings
Is it possible for a manager to have negative sharpe and treynor ratios and still be considered "good"?
Yes - relative measure
Suppose you have a fund whose returns are not consistently higher (or lower) that the market by a fixed amount. How could you estimate the funds alpha?
You would regress the excess return of that investment on the excess return of the market. The intercept of that equation is the fund's alpha
The information ratio allows to compare investments that have the same what?
alpha
The information ratio will always have the same sign as the ___
alpha
Undesirable volatility caused by negative excess returns
downside risk
Alpha divided by tracking error
information ratio
Measures investment performance as the raw portfolio return less the return predicted by the capital asset pricing model
jensen's alpha
The fact that a raw portfolio does not reflect any consideration of risk suggests that its usefulness is ____ when making investment decisions
limited
Beta gives us the ___ movement in the return of the stock for a given movement in the market or benchmark

A portfolio's or security's squared correlation to the market or benchmark
r-squared

relative
A basic measure of investment performance that includes an adjustment for risk

A measurement of how volatile a portfolio is relative to its benchmark
