Option Premiums Can be divided into two sections: Intrinsic value What is the option worth today? Time value How much time is left on the option? Intrinsic value depends on the futures price and the strike price of the option. Time value depends on the length of time in the option and the price volatility in the market.

Option Premiums Intrinsic value will not be less than zero. Remember, you have the right to exercise an option, not the obligation. So if the option is losing money, you can just let it expire. Time value will gradually approach zero as the expiration date approaches. Option premium = Intrinsic value + Time value Call intrinsic value = Underlying price - Strike price Put intrinsic value = Strike price - Underlying price

Example Start with an December corn 2019 put option @ $3.90 per bushel Day Futures Price Option Premium Intrinsic Value Time Value 1 $3.8550 $0.32375 $0.0450 $0.27875 2 $3.8725 $0.31125 $0.0275 $0.28375 3 $3.9625 $0.27375 $0.0000 4 $3.9450 5 $3.9325 $0.29125
