Put option is a contract that offers the buyers the right to sell an underlying asset at a predetermined price, known as the strike price, and within a specified time frame, known as the expiration date.
To be given the right to do that, the buyer has to pay a premium to the seller to compensate the seller for taking up the obligation.
Example: Assume the date today is 6 Dec 2021. The buyer of a put option has the right to exercise the put to sell 100 shares of Apple stock at $160 per share any time on, or before the expiration date of 7 Jan 2022, regardless of the market price of Apple by then. In exchange for this right to exercise the put option, he has to pay a premium of $540.
