Apple's Premarket Gain Would Add About Half a Point To The Dow

Apple Inc. may have to try a little harder to make a good first impression on its fellow Dow Jones Industrial Average components. The technology giant's stock, which is now officially a component of the blue-chip barometer, is up 17 cents, or 0.1%, at $128.64 in premarket trade Thursday. Using the new Dow divisor, which is used to calculate the index changes, Apple's gain would add about 1.13 points to the Dow's price . Dow futures are currently down 12 points.
