CAPM Flashcards
In the context of the Capital Asset Pricing Model (CAPM) the relevant risk is
Market risk
Once a portfolio is diversified, the only risk remaining is systematic risk, which is measured
by beta.
Which statement is true regarding the market portfolio?
A. It includes all publicly traded financial assets.
B. It lies on the efficient frontier.
C. All securities in the market portfolio are held in proportion to their market values.
E. it lies on a line that represents the expected risk-return relationship.
Which statement is not true regarding the market portfolio?
D. It is the tangency point between the capital market line and the indifference curve.
The tangency point between the capital market line and the indifference curve is the optimal
portfolio for a particular investor.
What is the difference between CML and SML?
Both the Capital Market Line and the Security Market Line depict risk/return relationships.
However, the risk measure for the CML is standard deviation and the risk measure for the
SML is beta
According to the Capital Asset Pricing Model (CAPM), overpriced securities
have negative alphas
Empirical results regarding betas estimated from historical data indicate that
Betas vary over time, betas may be negative or less than one, betas are not always near zero;
however, betas do appear to regress toward one over time.
A security has an expected rate of return of 0.10 and a beta of 1.1. The market expected
rate of return is 0.08 and the risk-free rate is 0.05. The alpha of the stock is
A. 1.7%.
B. -1.7%.
C. 8.3%.
D. 5.5%.
E. -5.5%.
10% - [5% + 1.1(8% - 5%)] = 1.7%.

What is the difference between sd and Beta?
Standard deviation and beta both measure risk, but they are different in that beta measures
only systematic risk while standard deviation is a measure of total risk.
The risk premium on the market portfolio will be proportional to
the average degree of risk aversion of the investor population and the risk of the market portfolio measured by its variance.
In equilibrium, the marginal price of risk for a risky security must be
equal to the marginal price of risk for the market. If not, investors will buy or sell the security until they are equal.
The capital asset pricing model assumes
all investors are price takers, all investors have the same holding period, and investors have homogeneous expectations.
The CAPM assumes that investors are price-takers with the same single holding period and
that there are no taxes or transaction costs.
- The capital asset pricing model assumes
all investors are fully informed, all investors are rational, and all investors are mean-variance optimizers.

If investors do not know their investment horizons for certain
the implications of the CAPM are not violated as long as investors’ liquidity needs are not priced.
One of the assumptions of the CAPM is that investors exhibit myopic behavior. What
does this mean?
They plan for one identical holding period
Myopic behavior is shortsighted, with no concern for medium-term or long-term implications.
