WALL STREET'S SLIDE: Large technology companies such as Alibaba and Baidu of China and U.S. tech giants including Facebook and Microsoft fell. The S&P 500 declined 0.8 percent to 2,818.37. Earlier it lost as much as 1.3 percent. The Dow Jones Industrial Average shed 0.5 percent to 25,162.41. The Nasdaq composite dropped 1.2 percent to 7,774.12. The Russell 2000 index of smaller-company stocks sank 1.3 percent to 1,670.67.
TENCENT SURPRISE: An unexpected drop in profits for Chinese tech giant Tencent rattled investors, adding to recent concerns about the health of China's economy. Tencent, a gaming and messaging company, is the most valuable technology company in China. Jefferies & Co. analyst Karen Chan said Tencent's revenue was also disappointing, mostly because of weak results from its mobile gaming business. Tencent's stock fell 3.2 percent in Hong Kong.
CHINA FACTOR: Earlier this week, reports on growth in factory output, consumer spending and retail sales in China were all slower than expected. But there was encouraging news in Beijing's announcement that it is sending a trade envoy to Washington, renewing efforts to resolve the worsening tariff dispute with the Trump administration.
ANALYST'S VIEWPOINT: Emerging market shares are taking a pinch from weak commodities prices, Mizuho Bank said in a commentary. Apart from that, "China's moderating growth also adds further concern given that its potential weaker import demand could ripple through the supply chain and hit export-oriented economies."
TURKEY'S TROUBLES: Turkey's currency fell 2.9 percent to 5.79 to the U.S. dollar. The country has imposed $500 million in tariffs on U.S. goods as tensions between the countries increase. There is also no sign that Turkey's president will let the central bank raise interest rates, which economists say it should do urgently to support the currency.
ENERGY: U.S. crude stabilized, adding 14 cents to $65.15 per barrel in electronic trading on the New York Mercantile Exchange. It sagged 3 percent to $65.01 a barrel in New York. Brent crude, the standard for international oil prices, picked up 40 cents to $71.16 per barrel. It had lost 2.3 percent to $70.76 a barrel in London.
