The stock price for Chevrolet is $35. An investor believes that
the stock price will experience significant volatility in the
following six months but is uncertain about the direction of the
share price movements. He decides to use a long straddle strategy
by buying both a put and a call option for Chevrolet, with the same
expiration date in 6 months and the same strike price of $35. The
investor paid a premium of $2.84 for the call option and a premium
of $1.46 for the put option.
What will be the net profit or loss for the investor if the
stock price is $38 on the expiration date of the options?
Investor B believes that Chevrolet stock price will stay in a
narrow range around $35 in the next 6 months. He decides to sell a
straddle by selling both a put option and a call option for
Chevrolet, with the same expiration date in June and the same
strike price of $35. What will be the net profit or loss for the
investor if the stock price is $32.12 on the expiration date
of the options?
How far can the stock price move in either direction before the
net profit of investor B becomes negative (in $)?
