Assume you purchased the right to sell $2,000$ shares of Target stock in March $2022$ at a strike price of $$210$ per share. Suppose Target stock sells for $$200$ 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 $$220$ per share $($think about it$)?$ Assume your holding period for this investment is exactly three months.

Note: A negative 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.
