Moneyness and value
Intrinsic value is immediate exercise value under the contract; option price also reflects remaining uncertainty and exercise opportunities, so payoff and price differ.
A call is in the money when spot exceeds strike; a put is in the money when strike exceeds spot, irrespective of the premium originally paid.
Pricing influences
For standard options all else equal, a higher underlying price raises call value and lowers put value; a higher strike has the opposite directional effect.
Greater volatility generally benefits a purchased vanilla option because upside exercise opportunity is retained while exercise is optional; this does not guarantee profit after paying a rich premium.
Exercise conventions
Dividends and financing rates affect call and put values through carry; separate a dividend forecast from the already observed spot movement.
American exercise permits action before expiry while European exercise is at expiry; early-exercise value depends on payouts, financing and contract terms.
State replication and no-arbitrage option bounds
A forward payoff is linear in the underlying, so cash plus underlying can replicate delivery at a fixed strike across all final prices. A call has a kink at strike and is not replicated globally by one constant stock/bond mix. A two-state binomial model can replicate it within the two modeled states, while a richer state space requires dynamic hedging or additional instruments.
For a European call on a non-dividend stock with positive financing rates, lower bound is max(S−PV(K),0), upper bound S. With S100,K100 and one-year5%, PV(K)=95.2381, lower bound4.7619. A call offered at3 would violate the frictionless lower bound; the arbitrage comparison must include stock, strike financing and the option. Dividends, early exercise and trading frictions require adjusted bounds.
Formula and assumptions
Call intrinsic=max(S−K,0); put intrinsic=max(K−S,0)
Original applied case: Option exercise value, time and sensitivities
- A call price is 9, spot 104 and strike 100; consider immediate exercise value only.
- Intrinsic value=4; price minus intrinsic=5 as the quoted time-value component.
- The 9 premium is not a guaranteed profit; exercise and investment profit require different calculations.
Errors to catch
- Do not assume: An option price must always equal current exercise value.
- Do not assume: Moneyness depends only on the premium paid.
- Do not assume: A higher underlying price lowers a standard call value.
