, Finance and Investment Questions
1) You are given the following information about an asset.
i) Using 36 years of data, the average annual asset return is 10%.
ii) The volatility of the asset’s return, over the same time period, was
estimated to be 27%.
iii) The distributions of each year’s returns are identically distributed and
independent from each other year’s returns.
Calculate the lower bound of the 95% confidence interval for the asset’s annual expected
return, using the approximation formula given in Corporate Finance.
(A) 1.0%
(B) 2.6%
(C) 4.5%
(D) 5.5%
(E) 8.5%

,Key: A
Because there are 36 years’ worth of data points and the distributions are IID, the
standard error is given by
= = = 0.045
SD 0.27
SE
n 36
Berk/DeMarzo equation 10.9 for the 95% confidence interval is
Historical Average Return ± (2 × Standard Error).
Thus, the lower bound of the 95% confidence interval is
0.10 − 2 × 0.045
= 0.10 − 0.09
= 0.01
= 1%.
