His annual rate of return = $2,046,000/$12,567,500 * 100 = -16.28%
Explanation:
The sculpture yielded a negative rate of return as it decreased in value over the 6-year period from $12,567,500 to $10,521,500. This represents a total negative return of $2,046,000 ($12,567,500 - $10,521,500). When this negative return is expressed in percentage terms, it gives a negative 16.28%. This percentage shows by how much the sculpture has decreased in value.
