**Question 271** CAPM, option, risk, systematic risk, systematic and idiosyncratic risk

All things remaining equal, according to the capital asset pricing model, if the systematic variance of an asset increases, its required return will increase and its price will decrease.

If the idiosyncratic variance of an asset increases, its price will be unchanged.

What is the relationship between the price of a call or put **option** and the total, systematic and idiosyncratic variance of the **underlying asset** that the option is based on? Select the most correct answer.

Call and put option prices **in**crease when the:

A stock's required total return will **increase** when its:

**Question 657** systematic and idiosyncratic risk, CAPM, no explanation

A stock's **required** total return will **decrease** when its:

A stock's total standard deviation of returns is **20**% pa. The market portfolio's total standard deviation of returns is **15**% pa. The beta of the stock is **0.8**.

What is the stock's **diversifiable** standard deviation?

**Question 776** market efficiency, systematic and idiosyncratic risk, beta, income and capital returns

Which of the following statements about returns is **NOT** correct? A stock's:

**Question 778** CML, systematic and idiosyncratic risk, portfolio risk, CAPM, no explanation

The capital market line (CML) is shown in the graph below. The total standard deviation is denoted by σ and the expected return is μ. Assume that markets are efficient so all assets are fairly priced.

Which of the below statements is **NOT** correct?

**Question 809** Markowitz portfolio theory, CAPM, Jensens alpha, CML, systematic and idiosyncratic risk

A graph of assets’ expected returns ##(\mu)## versus standard deviations ##(\sigma)## is given in the graph below. The CML is the capital market line.

Which of the following statements about this graph, Markowitz portfolio theory and the Capital Asset Pricing Model (CAPM) theory is **NOT** correct?

**Question 810** CAPM, systematic and idiosyncratic risk, market efficiency

Examine the graphs below. Assume that asset A is a single stock. Which of the following statements is **NOT** correct? **Asset A**:

**Question 875** omitted variable bias, systematic and idiosyncratic risk, CAPM, single factor model, two factor model

The Capital Asset Pricing Model (CAPM) and the Single Index Model (SIM) are single factor models whose only risk factor is the market portfolio’s return. Say a Solar electricity generator company and a Beach bathing chair renting company are influenced by two factors, the market portfolio return and cloud cover in the sky. When it's sunny and not cloudy, both the Solar and Beach companies’ stock prices do well. When there’s dense cloud cover and no sun, both do poorly. Assume that cloud coverage risk is a systematic risk that cannot be diversified and that cloud cover has zero correlation with the market portfolio’s returns.

Which of the following statements about these two stocks is **NOT** correct?

The CAPM and SIM:
