In this scenario, the optimal stock price for the option strategy would be \$45.00 on the date of the first expiration, September 20, 2024. This is equal to the strike price of the options in the spread. Since there is notable downward pressure in both the market and GM, and the strikes are below the current stock price of \$48.51, the spread is taking advantage of the market's bearish bias. If the stock price is \$45.00 at expiration, we can benefit from the 20-Sep-24 put, which we sold, expiring worthless, and the option that we are long, the 18-Oct-24 put, will still have time premium built in.

Since we do now know what the exact implied volatility will be on September 20, we can use our historical data to make an educated estimate to help us calculate the value of the 18-Oct-24 option. Applying the median historical implied volatility of 39.0 from similar options, the theoretical value of the put is 1.94 at the date of the 20-Sep-24 expiration. Using the above assumptions gives us a potential upside of +439% for this calendar spread.
