Stocks log 3-day losing streak; Dow posts worst week in 2013

Stocks finished slightly lower in lackluster trading Friday, extending their losses for a third-straight session, but major indexes still posted their first back-to-back weekly losses since late June.

The Dow and S&P 500 were down more than 3 percent from their all-time highs hit on Aug. 2.

"We've seen a brief correction of 3 to 5 percent off the recent highs and I would suspect the market to be choppy and sideways from here going into the next Fed meeting," said Matt Kaufler, portfolio manager of the Federated Clover Fund. "We're trying to add to more cyclically oriented sectors during this pullback."

The Dow Jones Industrial Average toggled in and out of positive territory. The blue-chip index broke below its 50-day moving average on Thursday. Hewlett-Packard led the blue-chip gainers, while Verizon declined.

The S&P 500 and the Nasdaq turned mixed. The S&P 500 traded near its 50-day moving average level of 1,656.7.

The CBOE Volatility Index (VIX), widely considered the best gauge of fear in the market, rose near 15.

Among key S&P sectors, defensive areas such as utilities and telecoms led the laggards on the heels of rising interest rates.

On the economic front, the consumer sentiment index slipped to 80 in August from 85.1 in July, according to the Thomson Reuters/University of Michigan's preliminary reading on the overall index. The reading missed expectations for 85.5 expected by economists surveyed by Reuters.

Housing starts rose 5.9 percent to a seasonally adjusted annual rate of 896,000 units in July, according to the Commerce Department, which was less than the expected 900,000 unit rate expected by economists polled by Reuters. June's starts were revised up to show a 846,000-unit pace instead of the previously reported 836,000 units.

"The housing numbers were reasonably healthy—they're not as robust as they were earlier in the year but there's been some concern about rates being notably higher and whether that's going to choke off the recovery in housing," said Kaufler. "And the consumer sentiment reading—even when it was a disappointing number—was already telegraphed by the recent weak reports from retailers." 

Most homebuilders including Pulte and DR Horton gained following the report. 

Kaufler said he is bullish on the homebuilders.

"By historic norms, even if rates tick up a little from here, I don't think it undercuts the rebound in housing," he explained.

And nonfarm productivity rose in the second quarter at a 0.9 percent annual rate as output increased more than hours worked, according to the Labor Department. Economists polled by Reuters had expected productivity to gain at a 0.6 percent rate.

Dell edged higher after the court cleared the way for a Sept. 12 vote on the company's buyout.
