A put is in-the-money when its exercise price is higher than the market value of the underlying asset. A put with a $35.00 strike price allows the trader to sell 100 shares of stock for $35.00 per share, which is $5.00 higher than the prevailing market value. This gives the put a value, hence, it is in-the-money. For a call to be in-the-money, its strike price would have to be lower than the market value of the underlying common stock, allowing the trader to purchase 100 shares at a price below the prevailing market value. At-the-money is when the strike price and asset market value are equal. A put with a strike price of $20.00 does not have intrinsic value because it is below the $30 price of the stock. It does have time value meaning it is worth something because there is the possibility the put will come into the money before it expires.
