Which of the following statements about systematic and unsystematic risk is least accurate?

A)
Total risk equals market risk plus firm-specific risk.

B)
As an investor increases the number of stocks in a portfolio, the systematic risk will remain constant.

C)
The unsystematic risk for a specific firm is similar to the unsystematic risk for other firms in the same industry.

This statement should read, "The unsystematic risk for a specific firm is not similar to the unsystematic risk for other firms in the same industry." Thus, other terms for this risk are firm-specific, or unique, risk.

Systematic risk is not diversifiable. As an investor increases the number of stocks in a portfolio the unsystematic risk will decrease at a decreasing rate. Total risk equals systematic (market) plus unsystematic (firm-specific) risk.

The other statements are false. Market risk cannot be reduced through diversification; market risk = systematic risk. The two classes of risk are unsystematic risk and systematic risk.

Which of the following statements about portfolio management is most accurate?

A)
Combining the capital market line (CML) (risk-free rate and efficient frontier) with an investor's indifference curve map separates out the decision to invest from the decision of what to invest in.

B)
The security market line (SML) measures systematic and unsystematic risk versus expected return; the CML measures total risk.

C)
As an investor diversifies away the unsystematic portion of risk, the correlation between his portfolio return and that of the market approaches negative one.

Combining the CML (risk-free rate and efficient frontier) with an investor’s indifference curve map separates out the decision to invest from what to invest in and is called the separation theorem. The investment selection process is thus simplified from stock picking to efficient portfolio construction through diversification.

The other statements are false. As an investor diversifies away the unsystematic portion of risk, the correlation between his portfolio return and that of the market approaches positive one. (Remember that the market portfolio has no unsystematic risk). The SML measures systematic risk, or beta risk.
