Year Risk-free Return Market Return XYZ Return
2011 2% 5% 9%
2012 1% -36% -49%
a. What was XYZ's average historical return? XYZ's average historical return was ______ (Round to one decimal place.) b. Compute the market's and XYZ's excess returns for each year. The market's excess return for 2011 was _______ (Round to the nearest integer.) The market's excess return for 2012 was ______ (Round to the nearest integer.) XYZ's excess return for 2011 was _______ (Round to the nearest integer.) XYZ's excess return for 2012 was _______ (Round to the nearest integer.) Estimate XYZ's beta. XYZ's beta is ______ (Round to two decimal places.) c. Estimate XYZ's historical alpha. XYZ's historical alpha was _______ (Round to one decimal place.
a. XYZ’s return in 2011 was 9% while the return in 2012 was (-) 49%, so the average historical return should be; (+9 – 49)/ 2 = -20%
b. Market’s excess return in 2011 is 3% (Market Return – Risk-free Rate). Market’s excess return in 2012 is -37% (Market Return – Risk-free Rate).
XYZ’s excess return in 2011 is 7% (XYZ Return – Risk-free Rate). Market’s excess return in 2012 is -50% (Market Return – Risk-free Rate).
Beta = 7% - (-50%)/ 3% - (-37%) = 57%/ 40% = 1.425
c. Historical Alpha = (XYZ’s excess return in 2011 + XYZ’s excess return in 2012)/2 – {Beta *[ (Market’s excess return in 2011 + Market’s excess return in 2012)/2]}
Alpha = (7-50)/2 – 1.425(3-37)/2 = -21.5 +24.225 = 2.725
