Hi! Could you please answer this simple question for me? This person was able to figure out the cost of his option. Here is what he wrote about a particular September QQQ put option: "the current price for qqq is at 22.09. The option is at 1.05 so you are really paying 23.14 for the price of the underlying QQQ. This is too expensive consider the short amount of time before expiration" My question is how did he figure out that the QQQ price is 23.14 from that option price of 1.05. Thank you so much.
