*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.
