Assume you purchased the right to sell 2,000 shares of Target stock in February 2022 at a strike price of $220 per share. Suppose Target stock sells for $210 per share immediately before your options expiration. What is the rate of return on your investment? What is your rate of return if the stock sells for $230 per share (think about it)? Assume your holding period for this investment is exactly three months.

Note: A negaive value should be indicated by a minus sign. Do not round intermediate calculations. Enter your 3-month returns as a percent rounded to 2 decimal places.
