At one time at least, a rule of thumb in the rarefied world of fine art collecting was "your
money back in 5 years, double your money in 10 years." Given this, let's see how an invest-
ment stacked up. In 2013, the Pablo Picasso painting Le Rêve was sold for $155 million.
The painting had reached a level of notoriety in part because its owner, casino magnate
Steve Wynn, had put his elbow through the middle of the painting. Wynn had purchased
the painting 12 years earlier in 2001 for an estimated $60 million. So was Wynn's gamble
a winner?
The rule of thumb has us doubling our money in 10 years; so, from the Rule of 72, we
have that 7.2 percent per year was the norm. The painting was resold in about 12 years. The
present value is $60 million, and the future value is $155 million. We need to solve for the
unknown rate, r, as follows:
$60,000,000 = $155,000,000/(1+r)¹²
(1+r) ¹² = 2.5833
Solving for r, we find that Wynn earned about 8.23 percent per year-a little better than
the 7.2 percent rule of thumb.
