3. Buffett purchased Berkshire Hathaway stock at $13 a share in 1965. By 2005, BRK stock was trading at $140,000 a share. What is the geometric return for Buffett’s investment in 40 years?
r = [Value in 2005 / Value in 1965]1/n - 1
= [$140,000 / $13]1/40 - 1
= [10,769.23]0.025 - 1
= 1.2613 - 1 = 0.2613, or 26.13%
