Dow Has Worst Day in Four Months

Weak outlooks and slowing growth

Stocks fell on Tuesday, driving the Dow industrials to the biggest drop since June 21, as weak results from index members DuPont and United Technologies showed profit growth is slowing.

This earnings season has so far produced a string of disappointments from companies falling short of Wall Street's expectations. With results in from 29 percent of S&P 500 companies, 37 percent have exceeded revenue forecasts, far short of the 62 percent average, and just 57.2 percent of the S&P 500 names reporting so far have beaten earnings forecasts, according to Thomson Reuters data.
