Amazon’s stock.

You own 100 stocks of Amazon’s stock. The current stock price is $3,120. You believe that the
stock price will double in two years, but you have a strong feeling that the stock price will drop in the next
six months due to the current economic conditions, you are not worried about this drop because you believe
it is temporary. Therefore, based on your expectations, you want to benefit from the stock price movement
by writing options without giving up your stock. The options available in the CBOE are as follows:
Option Type Strike Price Maturity
Call $3,080 3 Months
Call $3,100 3 Months
Call $3,120 3 Months
Put $3,080 3 Months
Put $3,100 3 Months
Put $3,120 3 Months
