Summary Box: Yields fall as factorys orders slip

WEAK DEMAND: The Commerce Department said orders to factories fell 0.5 percent in August, the third drop in four months.

LOWER YIELDS: Treasury yields dropped as their prices edged up. The 10-year yield, a widely used benchmark for interest rates on mortgages and corporate debt, slipped to 2.48 percent.

THE BACKDROP: Traders have pushed Treasury yields lower in recent weeks. They expect the Federal Reserve will try to sink long-term interest rates to spur borrowing and spending.
