Some investors and analysts use pre-market futures to predict how a stock will perform once the market opens. The stock index future price, which is the pre-market futures average, reflects what price the stock might open at. The stock index future price does not always correlate with the stock's actual opening price. At times the opening price might vary drastically from the index future price.
