US stocks posted modest losses in early trade Friday after a mixed report on durable goods orders pointed to a weakening manufacturing sector and a slowing economy.

The Dow Jones Industrial Average was down a scant 0.01 point (0.00 percent) at 13,057.45 at 16:45 SA time.

The S&P 500-stock index dropped 1.62 points (0.12 percent) to 1,400.46, while the tech-heavy Nasdaq fell 5.69 (0.19 percent) to 3,047.71.

“The US equity markets are seeing some pressure... in the wake of a mixed domestic durable goods orders report,” Charles Schwab & Co. analysts said.

New orders for durable goods in the United States surged more than expected in July, up 4.2 percent from June amid sharp rises in orders for aircraft and automobiles, the Commerce Department reported.

But excluding transportation, orders surprisingly fell for the second month in a row, by 0.4 percent.

Analysts said that behind the headline surge, the underlying data of the report were worrying, highlighting weakening in the manufacturing sector.

“This red flag suggests that manufacturing, which had been the mainstay of the recovery, could slow sharply over the coming months... and hinder the economy's ability to pick up from its paltry sub-2.0 percent growth rate recorded over the first two quarters of the year,” said analysts at RDQ Economics.
