At each final node of the tree—i.e. at expiration of the option—the option value is simply its intrinsic, or exercise, value: Max [ (S n − K), 0 ], for a call option Max [ (K − S n), 0 ], for a put option, Where K is the strike price and is the spot price of the underlying asset at the n th period.
Option time value. In finance, the time value (TV) (extrinsic or instrumental value) of an option is the premium a rational investor would pay over its current exercise value (intrinsic value), based on the probability it will increase in value before expiry. For an American option this value is always greater than zero in a fair market, thus ...
For a put option, the option is in-the-money if the strike price is higher than the underlying spot price; then the intrinsic value is the strike price minus the underlying spot price. Otherwise the intrinsic value is zero. For example, when a DJI call (bullish/long) option is 18,000 and the underlying DJI Index is priced at $18,050 then there ...
Thus, the option is said to have intrinsic value if the option is in-the-money; when out-of-the-money, its intrinsic value is zero. For an option, then, the intrinsic value is the same as the "immediate value" or the "current value" of the contract, which is the profit that could be gained by exercising the option immediately. Formulaically:
Strike price labeled on the graph of a call option. To the right, the option is in-the-money, and to the left, it is out-of-the-money. In finance, the strike price (or exercise price) of an option is a fixed price at which the owner of the option can buy (in the case of a call), or sell (in the case of a put), the underlying security or commodity.
The intrinsic value (or "monetary value") of an option is its value assuming it were exercised immediately. Thus if the current price of the underlying security (or commodity etc.) is above the agreed price, a call has positive intrinsic value (and is called "in the money"), while a put has zero intrinsic value (and is "out of the money").
The first part is the intrinsic value, which is defined as the difference between the market value of the underlying, and the strike price of the given option The second part is the time value , which depends on a set of other factors which, through a multi-variable, non-linear interrelationship, reflect the discounted expected value of that ...
Option values vary with the value of the underlying instrument over time. The price of the call contract must act as a proxy response for the valuation of: the expected intrinsic value of the option, defined as the expected value of the difference between the strike price and the market value, i.e., max[S−X, 0].
