U.S. stocks ended a choppy session little changed Friday, but logged another week of losses amid lackluster corporate earnings.
More than half of the S&P 500 companies have reported third-quarter financial results so far, and while more than 70% have delivered earnings above Wall Street's estimates, only 36% have topped sales forecasts, according to FactSet Research. That is well below the average of 55% that typically beat revenue estimates.
Moreover, companies have been tepid in their outlooks for the remainder of the year.
The dull results have pushed investors to the sidelines. In fact, all three indexes posted their second weekly loss in three weeks. The Dow Jones industrial average declined 1.8%, the S&P 500 slid 1.5%, and the Nasdaq dropped 0.6% during the week.
In addition, traders have become risk-averse ahead of the U.S. presidential elections, while concerns about the fiscal cliff continue to weigh on the market. The uncertainty has stocks on track to finish October in the red, logging their first monthly loss since May.
