The Dow Jones Transportation Average dropped 83 points, or 0.9%, to buck the rally in the broader stock market, with the selloff in railroad stocks and United Airlines' parent United Continental Holdings Inc. shares accounting for the bulk of the weakness. United's stock fell $3.29, or 4.2%, in morning trade in the wake of disappointing unit revenue guidance. That was shaving about 20 points off the Dow transports, which is a price-weighted index. Shares of CSX Corp. slumped $3.43, or 6.3%, after investors questioned how the railroad operator beat earnings expectations. That selloff knocked the Dow transports down by about 21 points. In sympathy, shares of Norfolk Southern Corp. shed $3.23, or 2.6%, and Union Pacific Corp.'s stock gave up $2.13, or 2.0%, to cut a combined 33 points from the Dow transports. Meanwhile, the Dow Jones Industrial Average rose 22 points, or 0.1%, while the S&P 500 tacked on 0.3% and the Nasdaq Composite gained 0.5%.
