Most Active Puts By Number

The buyer acquires a short position by purchasing the right to sell the underlying instrument to the seller of the option for a specified price (the strike price) during a specified period of time. If the option buyer exercises his right, the seller is obligated to buy the underlying instrument from him at the agreed-upon strike price, regardless of the current market price. In exchange for having this option, the buyer pays the seller or option writer a fee (the option premium).
