Construct an asymmetric butterfly using the 950-, 1020-, and
1050-strike options. What is the minimum number of each option you
should buy or sell? Draw a profit diagram for the position and
specify the dollar value of the maximum profit and maximum loss.
Assume c(950)=$120.405, p(950)=$51.777, c(1020)=p(1020)=$84.470,
c(1050)=$71.802, p(1050)=$$101.214.
