True or false?

-A stock with a Beta > 1 would be considered to be more risky than the overall stock market. -Beta is a measure of the unsystematic risk of a stock. -The basic premise of portfolio theory is that by adding stocks that have highly correlated returns to a portfolio reduces the overall risk of the portfolio. -The effect of an efficient portfolio is that systematic risk is largely eliminated. -If one wants to build an efficient portfolio consisting of two stocks, it would be best if returns of those two stocks have a correlation coefficient < 0. -Adding more stocks to a portfolio reduces the unsystematic risk of the portfolio. -The Security Market Line relates the expected return of a stock to its Beta. -In market equilibrium, the ratio of expected return to Beta for all stocks will be equal. -In portfolio theory, the risk-free rate has no impact on the 'reward-to-risk' ratio. -The Beta of a portfolio is the simple average of the Betas of the stocks in that portfolio. -The stock of a biotechnology company will most likely have a higher Beta than the stock of a public utility company. -In the Capital Asset Pricing Model, the expected return on a stock depends only on that assets unsystematic risk.
