Intrinsic Value vs Time Value
A premium is part real value, part hope. Splitting the two is the key to everything later.
Every option premiumThe price paid to buy an option. splits into exactly two parts: **intrinsic valueWhat an asset is really worth, based on its fundamentals. (real, exercisable value right now) and time value* (everything else — the value of possibility* before expiry). Premium = intrinsic + time value. Learning to split them is the key that unlocks the rest of optionsThe right, not the obligation, to buy or sell at a set price..
- Intrinsic valueWhat an asset is really worth, based on its fundamentals. — how much the optionThe right, not the obligation, to buy or sell at a set price. is ITMWhere an option’s strike sits relative to the current price. right now (a ₹950 callThe right, not the obligation, to buy or sell at a set price. with the stock at ₹1,000 has ₹50 intrinsic). OTMWhere an option’s strike sits relative to the current price./ATM options have zero intrinsic valueWhat an asset is really worth, based on its fundamentals..
- Time value — the premium above intrinsic valueWhat an asset is really worth, based on its fundamentals.: the market’s price for the chance that the optionThe right, not the obligation, to buy or sell at a set price. moves further into profit before expiry. It’s pure “hope,” and it depends on time left and volatilityThe size of price swings — not their direction..
Why does an option lose value even if the stock doesn’t move?
Because of time-value decay. Each day that passes removes some of the “possibility” premium, since there’s less time left for a favourable move. An option held flat slowly bleeds its time value — great for sellers (who collect it), painful for buyers (who pay it). This decay is the Greek *theta*.
