You think the price of AMZN stock, which is currently $900 is likely to change significantly over the next three months, you are just not sure which direction. So you buy a long straddle position, with a call and put option, worth $22 and $20 per share, respectively, three months to expiration, and a strike price of $900.

If at expiration AMZN is trading at $843, what is your net profit on this position?

Remember that option contracts come in multiples of 100 shares.
