Options Premium
The premium is the cost of purchasing an options contract and represents the maximum risk for the buyer.
Components of premium
Intrinsic value
The amount the option is in the money. A $50 call when the stock is at $55 has $5 of intrinsic value.
Time value (extrinsic value)
The portion of premium above intrinsic value. Reflects the probability the option could become more valuable before expiration.
What affects premium
- Stock price movement: Directly affects intrinsic value
- Time to expiration: More time = higher premium (time decay)
- Implied volatility: Higher IV = higher premiums
- Interest rates: Minor effect, increases call premiums slightly
- Dividends: Expected dividends decrease call premiums
Time decay (theta)
Options lose time value every day, accelerating as expiration approaches. This benefits option sellers and works against buyers.
Practical tip
Never pay a premium that requires an unrealistic stock move to be profitable. Calculate your breakeven before entering any options trade.
