Q

What is portfolio beta?

A

The weighted average of the betas of assets in a portfolio.

17
Q

What happens to the SML when inflation increases?

A

It shifts up, increasing required returns for all investments.

18
Q

What is the efficient frontier?

A

A set of optimal portfolios offering the highest return for a given level of risk.

19
Q

Why does diversification reduce risk?

A

It spreads investments, reducing unsystematic risk.

20
Q

What is the relationship between risk and return?

A

Higher risk = Higher potential return.

21
Q

How does CAPM determine expected return?

A

By using the risk-free rate, beta, and market return.

22
Q

What happens to required returns when risk aversion increases?

A

The market risk premium increases.

23
Q

What does a stock’s Sharpe Ratio measure?

A

How much excess return it generates per unit of risk.

24
Q

What is the difference between value and growth stocks?

A

Value stocks are undervalued; growth stocks are expensive but expected to grow fast.

25
Q

What happens to stock prices when interest rates rise?

A

Stock prices usually fall because bond yields become more attractive.

26
Q

What type of risk can be eliminated through diversification?

A

Unsystematic risk (company-specific risk).

27
Q

How does a diversified portfolio reduce risk?

A

It offsets losses in one stock with gains in another.

28
Q
