# Answer to Question #6126 in Economics of Enterprise for Lamarcus Streeter

Question #6126

1. Which of the following statements is CORRECT?

a. If you add enough randomly selected stocks to a portfolio, you can completely eliminate all of the market risk from the portfolio.

b. If you were restricted to investing in publicly traded common stocks, yet you wanted to minimize the riskiness of your portfolio as measured by its beta, then according to the CAPM theory you should invest an equal amount of money in each stock in the market. That is, if there were 10,000 traded stocks in the world, the least risky possible portfolio would include some shares of each one.

c. If you formed a portfolio that consisted of all stocks with betas less than 1.0, which is about half of all stocks, the portfolio would itself have a beta coefficient that is equal to the weighted average beta of the stocks in the portfolio, and that portfolio would have less risk than a portfolio that consisted of all stocks in the market.

d. Market risk can be eliminated by forming a large portfolio, and if some Treasury bonds are held

Expert's answer

b. If you were restricted to investing in publicly traded common stocks, yet you

wanted to minimize the riskiness of your portfolio as measured by its beta, then

according to the CAPM theory you should invest an equal amount of money in each

stock in the market. That is, if there were 10,000 traded stocks in the world,

the least risky possible portfolio would include some shares of each

one.

In finance, the

non-diversifiablerisk (also known as systematic risk or market risk), often represented by the quantity beta (β) in the financial industry, as well as the expected return of the market and the expected return of a theoretical risk-free asset.

In finance, the

**capital asset pricing model (CAPM)**is used to determine a theoretically appropriate required rate of return of an asset, if that asset is to be added to an already well-diversified portfolio, given that asset's non-diversifiable risk. The model takes into account the asset's sensitivity tonon-diversifiablerisk (also known as systematic risk or market risk), often represented by the quantity beta (β) in the financial industry, as well as the expected return of the market and the expected return of a theoretical risk-free asset.
