Important Terms In Options

(Strike price, In-the-money, Out-of-the-Money, At-the-Money, Covered call and Covered Put)
Strike price: The Strike Price denotes the price at which the buyer of the option has a right to purchase or sell the underlying. Five different strike prices will be available at any point of time. The strike price interval will be of 20. If the index is currently at 1,410, the strike prices available will be 1,370, 1,390, 1,410, 1,430, 1,450. The strike price is also called Exercise Price. This price is fixed by the exchange for the entire duration of the option depending on the movement of the underlying stock or index in the cash market.
In-the-money: A Call Option is said to be "In-the-Money" if the strike price is less than the market price of the underlying stock. A Put Option is In-The-Money when the strike price is greater than the market price.
eg: Raj purchases 1 SATCOM AUG 190 Call --Premium 10
In the above example, the option is "in-the-money", till the market price of SATCOM is ruling above the strike price of Rs 190, which is the price at which Raj would like to buy 100 shares anytime before the end of August.
Similarly, if Raj had purchased a Put at the same strike price, the option would have been "in-the- money", if the market price of SATCOM was lower than Rs 190 per share.
Out-of-the-Money: A Call Option is said to be "Out-of-the-Money" if the strike price is greater than the market price of the stock. A Put option is Out-Of-Money if the strike price is less than the market price.
eg: Sam purchases 1 INFTEC AUG 3500 Call --Premium 150
In the above example, the option is "out-of- the- money", if the market price of INFTEC is ruling below the strike price of Rs 3500, which is the price at which SAM would like to buy 100 shares anytime before the end of August.
Similarly, if Sam had purchased a Put at the same strike price, the option would have been "out-of-the-money", if the market price of INFTEC was above Rs 3500 per share.
At-the-Money: The option with strike price equal to that of the market price of the stock is considered as being "At-the-Money" or Near-the-Money.
eg: Raj purchases 1 ACC AUG 150 Call or Put--Premium 10
In the above case, if the market price of ACC is ruling at Rs 150, which is equal to the strike price, then the option is said to be "at-the-money".
If the index is currently at 1,410, the strike prices available will be 1,370, 1,390, 1,410, 1,430, 1,450. The strike prices for a call option that are greater than the underlying (Nifty or Sensex) are said to be out-of-the-money in this case 1430 and 1450 considering that the underlying is at 1410. Similarly in-the-money strike prices will be 1,370 and 1,390, which are lower than the underlying of 1,410.
At these prices one can take either a positive or negative view on the markets i.e. both call and put options will be available. Therefore, for a single series 10 options (5 calls and 5 puts) will be available and considering that there are three series a total number of 30 options will be available to take positions in.
