Term

Factor portfolio (definition)

 

Arbitrage portfolio

 

Tracking portfolio

Definition

A factor portfolio is a portfolio with a factor sensitivity of one to a particular factor and zero to all other factors.

 

An arbitrage portfolio is a portfolio with factor sensitivities of zero to all factors, positive expected net cash flow, and an initial investment of zero.

 

A tracking portfolio is a portfolio with a specific set of factor sensitivities designed to replicate the factor exposures of a benchmark index.

Term

Macroeconomic factor models:

Definition

Macroeconomic factor models use unexpected changes (surprises) in macroeconomic variables as the factors to explain asset returns. One example of a factor in this type of model is the unexpected change in gross domestic product (GDP) growth

Term

Fundamental factor models use: 

Definition

In fundamental factor models, the factors are characteristics of the stock or the company that have been shown to affect asset returns, such as book-to-market or price-to-earnings ratios.

Term

A statistical factor model:

Definition

identifies the portfolios that best explain the historical cross-sectional returns or covariances among assets. The returns on these portfolios represent the factors.

Term

If an investors’ portfolio lies on the capital market line (CML) at the point where the CML touches the efficient frontier then this implies the investor has:

Definition

100% of their funds invested in the market portfolio

Term

Valid methods for reducing instability in the minimum variance frontier (2):

Definition

(1) Improving the statistical quality of inputs

(2) adding constraints against short sales 

Term

Mean-variance analysis assumes that investors only need to know ______ (3 things) in order create optimal portfolios.

Definition

(1) expected returns

(2) variances

(3) covariances

Term

The SML graphically represents the relationship between:

Definition

return and systematic risk (as measured by beta)

Term
Expected return on portfolio using CML (formula) + slope of CML (formula) and what it equals
Definition

E(Rp) = RFR + [(E(RM) - RFR) / SM]*Sp

E(RM) = expected return on market portfolio

SM = SD of market portfolio

SP = SD of portfolio

 

SLOPE of CML = [(E(RM) - RFR) / SM]

equals SHARPE RATIO

Term

Variance of an equally-weighted portfolio:

(2)

 

Previous formula establishes:

(1) Number of stocks to acheive diversification

(2) Higher average correlation, _____ stocks it takes to acheive diversification

Definition

Varp = (1/n)(s21) + [(n-1)/n]*cov

 

Varp = s21*[(1-p)/n + p] 

n = # of assets

cov = average covariance

p=correlation

 

(1) relatively small number

(2) fewer

Term

The multifactor model is:

Definition

a time-series regression that explains variation in one asset

Term

Macrofactor models (3 things):

 

Fundamental factor models (2 things):

Definition

Macrofactor models include explanatory variables such as the business cycle, interest rates, and inflation

 

Fundamental factor models include explanatory variables such as firm size and the price-to-earnings ratio. 

Term

The risk and return coordinate for the market portfolio is:

Definition

the tangency point for the capital market line (CML)

Term

The CML has the ______ slope of any possible portfolio combination.

 

The slope of the CML is ______ and is maximized for the ________

Definition

steepest

 

the Sharpe ratio. Maximized for market portfolio

Term

Tolerance for risk for endowments and foundations?

Definition

Average or above average tolerance for risk, in part due to their relatively longer investment time horizons. 

Term

What portfolio(s) will plot on the SML?

 

What portfolio(s) will plot on the CML?

Definition

All portfolios will plot on the SML.

 

The only portfolio that will plot on the CML is the market portfolio, because it is perfectly diversified.

Term

Investment constraints (6 things):

Definition

(1) liquidity needs

(2) time horizon

(3) tax concerns

(4) legal factors

(5) regulatory factors

(6) unique circumstances

Term
An investor's risk tolerance is included under (category):
Definition
objectives
Term

The CAPM predicts that all investors hold the ______

 

The capital allocation line is then the _____ and the market price of risk is ______.

 

The security market line (SML) describes the relationship between ______, where risk is measured by _____.

Definition

market portfolio

 

capital market line (CML) and the market price of risk is the slope of the CML.

 

between asset risk and expected return, where risk is measured by beta

Term
Alpha returns:
Definition
Returns beyond the required return expected on an asset given its level of risk
Term

CAPM (does/not) assume that all investors hold the market portfolio.

 

APT (does/not).....

Definition
CAPM does assume; APT does not
Term

 

Because the CML is a straight line, it implies that all the portfolios on the CML are:

Definition

 

perfectly positively correlated

Term

As the number of variables in a regression increases, effect on:

(1) R2

(2) Adjusted R2

(3) F-statistic

Definition

 

(1) always increases

(2) up/down

(3) up/down

Term
Variance of a 3-asset portfolio (2):
Definition

Same as 2-asset, but after 2W1W2 terms do:

 

(1) cov(1,2)

or

(2) p(1,2)s1s2

Term

Capital Allocation Line (CAL):

(1) graphically

(2) best risky portfolio

(3) formula for best risky portfolio

(4) formula for CAL

(5) formula for CML when mkt portfolio is tangency port.

Definition

(1) line from the RFR to the point of tangency of the efficient frontier

(2) pt of tangency between CAL and efficient frontier

(3) Sharpe ratio

(4) E(RCAL) = Rf + [E(Rp)-Rf/sp]*sp

(5) same as CAL just do R(market) instead of R(p)

Term

The market model (used for + formula):

 

Makes 3 predictions (formulas):

Definition

Regression model often used to estimate betas for common stocks

Return(i) = Alpha(i) + Beta(i)*Return(Mkt) + Error


(1) E(Returni) = Alpha(i) + Beta(i)*E(Rmkt)

(2) Variance(i) = Betai2*sm2 + s2error

(3) Covij = BetaiBetajs2M

Term
Adjusted Beta
Definition

Forecast Betai,t = Alpha0 + Alpha1Betai,t-1

 

Alpha0 = 1/3      Alpha1 = 2/3
