You're buying or selling the future position with another party and cannot control what they are doing. Most futures are cash settled and they affect markets all the same. Nearly $200b worth of S&P 500 E-Mini contracts traded today and not a single share of stock will be directly involved in those contracts. But you better believe they move the market (just watch what happens when a monster ES order hits the tape).
