What Is the Difference between the Theoretical Futures Price and the Market Futures Price?
The theoretical futures price is the price derived from the cost-of-carry model (Spot Price + Cost of Carry). The market futures price is the actual price at which the contract is currently trading on the exchange.
The difference between the two is a temporary mispricing. Arbitrageurs constantly work to close this gap, but it can exist due to transaction costs, market inefficiencies, or differing market expectations.
