Thursday's trading turned on an unexpected drop in existing home sales, and there are a few key numbers on today's calendar which may also be market movers. The government is out with durable goods orders for August at 8:30 am New York time, with economists looking for a gain of 0.3 percent.
The University of Michigan is out with its latest reading on consumer sentiment at 9:55 am, with a slight increase expected. And new home sales for August are out at 10 am, with consensus forecasts calling for a 1.6 percent increase over July.
