US stocks posted losses on Friday, the last trading day of the third quarter, after disappointing business activity and consumer spending reports fueled concerns about the economy.

The major indices closed off the worst levels of the day after results of Spain’s bank stress tests were basically in line with expectations, analysts said.

The Dow Jones Industrial Average was down 50.15 points (0.37 percent) at 13,435.82 in closing trade.

The S&P 500-stock index fell 6.53 (0.45 percent) to 1440.62 and the tech-rich Nasdaq Composite shed 20.37 (0.65 percent) at 3116.22.
