Question

The optimal risky portfolio can be identified by finding ____________. I. the minimum variance point on the efficient frontier II. the maximum return point on the efficient frontier the minimum variance point on the efficient frontier III. the tangency point of the capital market line and the efficient frontier IV. the line with the steepest slope that connects the risk free rate to the efficient frontier A. I and II only B. II and III only C. I and IV only D. III and IV only

Answer 1

D. III and IV only.

Step-by-step explanation:

Portfolio variance can be defined as the measurement of risk or dispersion of returns of a set of securities that makes up a portfolio fluctuate over a period of time.

Simply stated, portfolio variance is typically the total returns of the portfolio over a specific period of time.

In order to calculate the portfolio variance, the standard deviations of each security in the portfolio with their respective correlations security pair in the portfolio would be used. Portfolio variance is the square of standard deviation.

A two-asset portfolio with a standard deviation of zero can be formed when the assets have a correlation coefficient equal to negative one (-1) because this defines the efficiency frontier. In Economical portfolio theory, the efficient frontier is a group of optimal portfolios that offers an investor the highest expected return for a specific risk level or offers the lowest risk for a defined level of expected return.

A common risk can be defined as a type of risk that affects the entirety of a business firm or company and as such can't be diversified.

Generally, the optimal risky portfolio can be identified by finding the tangency point of the capital market line and the efficient frontier and the line with the steepest slope that connects the risk free rate to the efficient frontier.
