Apple's stock surge set to add over 70 points to the Dow's price

Apple Inc.'s stock surge is fueling the bulk of the lift in Dow Jones Industrial Average futures ahead of Wednesday's open, in the wake of the technology giant's fiscal second-quarter earnings and revenue beats. The stock rallied 5.3% in premarket trade, which puts it on track to open at the highest price seen during regular-session hours since Nov. 2. The implied price gain would add about 72 points to the Dow's price, while Dow futures were up 98 points. Apple's stock has run up 20.5% over the past three months, while the Dow has gained 6.1%.
