The option premium, as we all by now understand, is the price that the buyer pays to the seller for getting the right to buy without the obligation to buy. This option premium has 2 components viz. time value and intrinsic value. The intrinsic value is the price profit while the time value is the probability that the market is assigning to the option becoming profitable. All ITM options will have intrinsic value and time value while OTM options will only have time value. When we say that the option value is diminishing as expiry approaches then we are talking about time value only. That is the concept of theta which is popularly used by option sellers. Let us look at a live illustration to grasp this point better.

Assume that Infosys is quoting at Rs.1000. Let us look at various scenarios of call option strike prices and how the split of time value and intrinsic value is worked outâ€¦
