NEW YORK - Shares of Apple plunged at the start of trading on Thursday, weighing on the broader market after the tech giant cut its sales forecast due to weakness in China.

The Dow Jones Industrial Average tumbled 1.4 percent to 23,027.14, while the broad-based S&P 500 slid 1.0 percent to 2,486.25.

On the positive side, an ADP employment report showed private-sector firms added 271,000 jobs in December, well above analyst forecasts.
The data came ahead of Friday's more closely-watched Department of Labor report. Analysts expect the US added 180,000 jobs last month and unemployment held at 3.7 percent.
