A put option is an option contract giving the owner the right, but not the obligation, to sell a specified amount of an underlying security at a specified price within a specified time.
This is the opposite of a call option, which gives the holder the right to buy shares.
A put option becomes more valuable as the price of the underlying stock depreciates relative to the strike price.The value of a put option decreases due to time decay, because the probability of the stock falling below the specified strike price decreases.
When an option loses its time value, the intrinsic value is left over, which is equivalent to the difference between the strike price less the stock price.
Out-of-the-money and at-the-money put options have an intrinsic value of zero because there would be no benefit of exercising the option.
