1st LD Writethru: U.S. stocks tumble with global shares

U.S. stocks declined for the fourth straight session amid mixed earnings Friday, as a broad- based sell-off in overseas stock markets triggered worries of a slowing growth in global economy.

The Dow Jones Industrial Average dipped 163.39 points, or 0.92 percent, to 17,568.53. The S&P 500 shed 22.50 points, or 1.07 percent, to 2,079.65. The Nasdaq Composite Index plunged 57.78 points, or 1.12 percent, to 5,088.63.

Euro area's manufacturing purchasing managers' index (PMI) flash, a gauge of the industry activities, fell to 52.2 in July, said Markit Economics Limited Friday.

European equities ended sharply lower Friday as signs of slower global growth weighed on market sentiment, with Germany's benchmark DAX index at Frankfurt Stock Exchange falling 1.43 percent.

In Asia, Chinese shares ended a six-day winning streak amid weak economic data Friday, with the benchmark Shanghai Composite Index closing 1.29 percent lower. Tokyo shares also declined on a stronger yen, with the 225-issue Nikkei Stock Average down 0.67 percent.

In corporate news, Amazon.com soared 9.80 percent to 529.42 dollars a share Friday after the online retail giant posted an unexpected quarterly profit.

The e-commerce firm's net sales increased 20 percent to 23.18 billion U.S. dollars in the second quarter 2015, compared with 19. 34 billion dollars in the second quarter 2014. Net income was 92 million dollars in the second quarter 2015, compared with a net loss of 126 million dollars in the same period a year earlier.

On the economic front, U.S. sales of new single-family houses in June were at a seasonally-adjusted annual rate of 482,000, well below market consensus and down 6.8 percent from the revised May level of 517,000, said the Commerce Department Friday.

"June's much weaker-than-expected new home sales, coupled with downward revisions to the past three months, is at odds with other recent housing data, suggesting the summer selling season is not as strong as initially thought," said Sophia Kearney-Lederman, an economic analyst at FTN Financial, in a note.

For the week, the three major indices suffer big losses, with the Dow, the S&P 500 and the Nasdaq dropping 2.9 percent, 2.2 percent and 2.3 percent, respectively. Endite
