Don't expect the surge in General Electric Co.'s stock in premarket trade Friday to give the Dow Jones Industrial Average too big of a boost, because GE is the blue-chip barometer's lowest-priced stock, and the Dow is a price-weighted index. The stock is trading up 4.3% at $26.81 after the industrial conglomerate announced a $50 billion share buyback program, putting it on an early track to open at the highest level since Nov. 28, 2014. Meanwhile, the price gain of $1.08 would add just 7.2 points to the Dow. A $1.08 rise in the Dow's highest-priced stock -- Goldman Sachs Group -- would represent just a 0.6% move.
