1. (10 points) An investor wants to use a long straddle, the current market index being 100. He buys the six-month call with exercise price 100 for $1.80 and the six-month put with exercise price 100 at $1.50. If the market rises to 150 at the end of six months, what is the investor's profit or loss? If the market falls to 80 at the end of six months, what is the investor's profit or loss? If the market stays at 100 at the end of six months, what is the profit or loss? Calculate the breakeven points (upside and downside) for the straddle
