Stand-alone risk is the risk an investor would face if he or she held only -Select- No investment should be undertaken unless its expected rate of return is high enough to compensate for its perceived -Select The expected rate of return is the return expected to be realized from an investment; it is calculated as the of the probability distribution of possible results as shown below: -Select- N Expected rate of return = f = P111 + Pyr2 + ... +PNIN = Pin 1 The -Select- van asset's probability distribution, the lower its risk. Three useful measures of stand-alone risk are standard deviation, coefficient of variation, and the Sharpe ratio. Standard deviation is a statistical measure of the variability of a set of observations as shown below: N Standard deviation === [(-i)", i t-1 If you have a sample of actual historical data, then the standard deviation calculation would be changed as follows: . (: - FAve) Estimated o= N-1 The coefficient of variation is a better measure of stand-alone risk than standard deviation because it is a standardized measure of risk per unit; it is calculated as the Select- divided by the expected return. The coefficient of variation shows the risk per unit of return, so it provides a more meaningful risk measure when the expected returns on two alternatives are not -Select- The Sharpe ratio compares the asset's realized excess return to its -Select- over a specified period. Excess returns measure the amount that investment returns are above the risk-free rate - 50 investments with returns equal to the risk-free rate will have a -Select- Sharpe ratio. It follows that over a given time period, Investments with Select Sharpe ratios performed better, because they generated higher Select excess returns per unit of risk. The Sharpe ratio is calculated as: Sharpe ratio = (Return - Risk-free rate)/ measure when the expected returns on two alternatives are not -Select- The Sharpe ratio compares the asset's realized excess return to its -Select- over a specified period. Excess returns measure the amount that investment returns are above the risk-free rate - so Investments with returns equal to the risk-free rate will have a -Select- Sharpe ratio. It follows that over a given time period, investments with -Select- Sharpe ratios performed better, because they generated higher -Select- excess returns per unit of risk. The Sharpe ratio is calculated as: Sharpe ratio = (Return - Risk-free rate)/o Quantitative Problem: You are given the following probability distribution for CHC Enterprises: State of Economy Probability Rate of return Strong 0.15 19% Normal 0.45 10% Weak 0.40 -6% What is the stock's expected return?
