You invest $10,000 in a complete portfolio. The complete portfolio is composed of a risky asset with an expected rate of return of 15% and a standard deviation of 21% and a Treasury bill with a rate of return of 5%. How much money should be invested in the risky asset to form a portfolio with an expected return of 11%?
15y + 5(1 - y) = 11; y = 60%; .60(10,000) = $6,000

You are considering investing $1,000 in a complete portfolio. The complete portfolio is composed of Treasury bills that pay 5% and a risky portfolio, P, constructed with two risky securities, X and Y. The optimal weights of X and Y in P are 60% and 40% respectively. X has an expected rate of return of 14%, and Y has an expected rate of return of 10%. To form a complete portfolio with an expected rate of return of 8%, you should invest approximately __________ in the risky portfolio. This will mean you will also invest approximately __________ and __________ of your complete portfolio in security X and Y,
E(rp) = .6(14) + .4(10) = 12.4% .08 = wrp(.124) + (1 - wrp)(.05) wrp ≈ 40% wx in complete portfolio = .40(.60) = 24% wy in complete portfolio = .40(.40) = 16%
You have an EAR of 9%. The equivalent APR with continuous compounding is _____.
LN[1 + .09] = 8.62%
The price of a stock is $55 at the beginning of the year and $50 at the end of the year. If the stock paid a $3 dividend and inflation was 3%, what is the real holding-period return for the year?
Nominal return on stock: (50 + 3)/55 - 1 = −3.64% Real return: (1 + R) = (1 + r)(1 + i) 1 + r = (1 - .0364)/(1.03) = .935 R = .935 - 1 = -.0644
A security with normally distributed returns has an annual expected return of 18% and standard deviation of 23%. The probability of getting a return between -28% and 64% in any one year is _____.
Note that the expected return minus 2 standard deviations is 18% - (2 × 23%) = -28% and the expected return plus 2 standard deviations is 18% + (2 × 23%) = 64%. The probability of a return falling within ± 2 standard deviations is 95.44%.
If you are promised a nominal return of 12% on a 1-year investment, and you expect the rate of inflation to be 3%, what real rate do you expect to earn?
Real rate = (1.12/1.03) - 1 = 8.74%
Which one of the following would be considered a risk-free asset in real terms as opposed to nominal?
U.S. T-bill whose return was indexed to inflation
The geometric average of -12%, 20%, and 25% is _________.
[(1 + −.12)(1 + .20)(1 + .25)]^(1/3) - 1 = 9.70%
The ______ measure of returns ignores compounding
arithmetic average
You have calculated the historical dollar-weighted return, annual geometric average return, and annual arithmetic average return. If you desire to forecast performance for next year, the best forecast will be given by the ________.
arithmetic average return
(NOT ON TEST) Two assets have the following expected returns and standard deviations when the risk-free rate is 5%: Asset A, E(ra)= 10%, σA = 20% Asset B, E(rb)= 15%, σB = 27% An investor with a risk aversion of A = 3 would find that _________________ on a risk-return basis.
neither asset A nor asset B is acceptable A= (E(r1)-Rf)/ σQ^2 Minimum Acceptable Return is given by E(rp)=(A * σQ^2)+rf For A: E(ra) =(3*.04)+.05=17% For B: E(rB)= (3*.729)+ .05=26.87%

E(rp)= (.4)(.15)+(.5)(.10)+(.10)(-.03)= 10.7% σP= .4(.15-.107)^2 + .5(10-.107)^ 2 +.10(-.03-.107)^2 σP= 5.14%
