• The Dow Jones Industrial Average .DJI fell 137.51 points, or 0.54 percent, to 25,162.41, the S&P 500 .SPX lost 21.59 points, or 0.76 percent, to 2,818.37 and the Nasdaq Composite .IXIC dropped 96.78 points, or 1.23 percent, to 7,774.12.

Wall Street fell in a day of heavy trading on Wednesday with the S&P 500 posting its biggest percentage drop since late June as investors turned risk-averse on disappointing earnings and escalating global tariff worries.

• Equities around the world took a dive led by emerging market stocks on Wednesday and commodities tumbled as investors looked for safety due to worries about China and Turkey.

While fears of a crisis in Turkey still loomed, China was in sharp focus as the yuan CNH=EBS sagged nearly 0.8 percent to 6.9514 per dollar, hitting its weakest level since January 2017.

• On top of China’s disappointing economic data earlier in the week, technology firm Tencent Holdings Ltd (0700.HK) reported its first quarterly profit fall in nearly13 years on weak gaming revenue.

• “A combination of fears of contagion from Turkey and a possibility of a China slowdown has upset markets worldwide. It’s more of a risk off trade,” said JJ Kinahan, chief market strategist at TD Ameritrade in Chicago.

• Asian shares declined on Thursday, taking cues from losses on Wall Street after Chinese internet giant Tencent reported a fall in quarterly profit — a disappointing result that weighed on the tech space stateside.

• The Nikkei 225 fell by 1.38 percent in early hours trade, with all sectors in Tokyo recording losses, as the oil and coal producers saw the largest decline of 5.3 percent.

• South Korea's Kospi declined by 1.40 percent, as its tech sector largely took a hit after their counterparts on Wall Street came under pressure overnight. SK Hynix was among the major names affected, sliding 3.82 percent while Samsung Electronics saw a fall of 2.55 percent.
