11.2 The Volatility of a Two-Stock Portfolio

1) Which of the following statements is false?

A) The covariance and correlation allow us to measure the co-movement of returns.

B) Correlation is the expected product of the deviations of two returns.

C) Because the prices of the stocks do not move identically, some of the risk is averaged out in a portfolio.

D) The amount of risk that is eliminated in a portfolio depends on the degree to which the stocks face common risks and their prices move together.

2) Which of the following statements is false?

A) While the sign of the correlation is easy to interpret, its magnitude is not.

B) Independent risks are uncorrelated.

C) When the covariance equals 0, the returns are uncorrelated.

D) To find the risk of a portfolio, we need to know more than the risk and return of the component stocks; we need to know the degree to which the stocks\\\\\\\' returns move together.

3) Which of the following statements is false?

A) Dividing the covariance by the volatilities ensures that correlation is always between -1 and +1.

B) Volatility is the square root of variance.

C) The closer the correlation is to 0, the more the returns tend to move together as a result of common risk.

D) If two stocks move together, their returns will tend to be above or below average at the same time, and the covariance will be positive.

4) Which of the following statements is false?

A) Stock returns will tend to move together if they are affect similarly by economic events.

B) Stocks in the same industry tend to have more highly correlated returns than stocks in different industries.

C) Almost all of the correlations between stocks are negative, illustrating the general tendency of stocks to move together.

D) With a positive amount invest in each stock, the more the stocks move together and the higher their covariance or correlation, the more variable the portfolio will be.

5) Which of the following statements is false?

A) A stock\\\\\\\'s return is perfectly positively correlated with itself.

B) When the covariance equals 0, the stocks have no tendency to move either together or in opposition of one another.

C) The closer the correlation is to -1, the more the returns tend to move in opposite directions.

D) The variance of a portfolio depends only on the variance of the individual stocks.

6) Which of the following statements is false?

A) If two stocks move in opposite directions, one will tend to be above average when to other is below average, and the covariance will be negative.

B) The correlation between two stocks has the same sign as their covariance, so it has a similar interpretation.

C) The covariance of a stock with itself is simply its variance.

D) The covariance allows us to gauge the strength of the relationship between stocks.

7) Which of the following equations is incorrect?

A) Cov(Ri,Rj) = ?(Ri - Ri)(Rj - Rj)

B) Var(Rp) = x12Var(R1) + x22Var(R2) + 2X1X2Cov(R1,R2)

C) Corr(Ri,Rj) =

D) Cov(Ri,Rj) = E[(Ri - E[Ri])(Rj - E[Rj])]
