This package of investments is known as a “butterfly.” a. What package of investments would provide you with this set of payoffs? b. How much would the package have cost you in July 2010? c. In what circumstances might it make sense to invest in this package? Incidentally, this package of investments is known as a “straddle” by option buffs.
