Chapter 11.5, Problem 11.5ACQ
Summary Introduction
To discuss: The impact of increasing the number of assets in the portfolio on the standard deviation.
Introduction:
Risk refers to the movement or fluctuation in the value of an investment. The movement can be positive or negative. A positive fluctuation in the price benefits the investor. The investor will lose money if the price movement in negative.
Standard deviation refers to the deviation of the actual returns from the expected returns.
Diversification refers to the process of investing in multiple investment avenues.
