Intrinsic & Time Value

• Option premiums can be divided into two parts.

• Intrinsic value: Is the amount the option is ITM. Its zero for ATM and OTM.

• Time value is the difference between its premium and its intrinsic value.

• Usually Time Value is maximum when the call/Put is ATM.

IN, AT , OUT-OF-THE-MONEY

• To identify whether an option is IN-, AT- or OUT-OF-THE-MONEY, one need only compare the EXERCISE PRICE of the option to the STOCK PRICE of the underlying asset.

• KEEP IN MIND THAT... • In-the-Money Options have INTRINSIC VALUE

• At-the-Money Options have INTRINSIC VALUE EQUAL TO ZERO

Stock Options: Example• An Indian Investor has to deliver 100 shares of

ACC in 60 days. He buys a call option at a price of Rs. 20 and the strike price is Rs. 200 per share.

• Premium Paid by the Investor:

Rs. 2,000 or , (Rs. 20 X 100).

• If at the time of payment :-

ACC has risen to Rs. 230 per share - In - the - Money position (Profit = Rs. 3,000 – 2,000) = Rs. 1,000

ACC declined to Rs.190 -Out-of-Money position
