Stock futures are different from stock options. With futures, the contract holder is obligated to fulfill the terms of the contract based on the predetermined future date and price, according to Investopedia. With stock options, the contract holder keeps his right to buy or sell an underlying asset until the expiration date. The asset can either be a financial instrument or a physical commodity. All future contracts detail the quality and quantity of the underlying asset.
