Final answer:
The risk-adjusted return is typically calculated by subtracting the inflation rate and the risk-free rate from the actual rate of return. Given the information provided, which includes a 90-day T-bill rate of 4%, an actual return of 14%, a CPI of 3%, and no market return, the risk-adjusted return is 7%. None of the options given match the calculated value.
Step-by-step explanation:
To calculate the risk-adjusted return, given the following information: 90-day T-bill rate: 4%, Actual return: 14%, Beta = 1.4, CPI (Consumer Price Index): 3%, and Standard deviation: 5.0%, we can use the Capital Asset Pricing Model (CAPM) which suggests that the expected return of an investment equals the risk-free rate plus a risk premium. The risk-free rate is the return of an investment with no risk of financial loss, like the 90-day T-bill rate. The risk premium is the return in excess of the risk-free rate, which is the product of the investment's beta and the market risk premium (the expected market return minus the risk-free rate).
The formula to calculate the expected return using CAPM is: Expected Return = Risk-Free Rate + Beta * (Market Return - Risk-Free Rate).
However, the question provided does not include the market return, and instead, it requires us to find the risk-adjusted return. This is often done by adjusting the actual return for the risk-free rate and sometimes for inflation as well. Inflation can erode the purchasing power of money, so adjusting returns for inflation provides a more accurate measure of the 'real' return.
Given that we do not have all the parameters for the CAPM, we will assume that the risk-adjusted return for this purpose means the actual return minus the inflation rate and the risk-free rate: Risk-Adjusted Return = Actual Return - Inflation Rate - Risk-Free Rate.
Therefore, Risk-Adjusted Return = 14% - 3% (CPI) - 4% (90-day T-bill rate) = 7%.
None of the options provided A) 9.4% B) 10.6% C) 11.8% D) 12.2% match the calculated risk-adjusted return of 7%. It is possible that the question may be incomplete or could be asking for a different type of risk-adjusted return that requires additional information or formulas not provided.
