TOKYO, Feb 17 (Reuters) - Japan's Nikkei share average fell in choppy trade on Wednesday morning despite gains on Wall Street as investors remained wary after recent market turmoil and amid more oil price volatility.
The Nikkei dropped 0.5 percent to 15,974.23 in mid-morning trade, swinging between positive and negative territory.
Trading was directionless amid problems ranging from a global economic slowdown, weak oil prices and concerns about banks' businesses after the Bank Of Japan announced a negative interest rate policy, as well as worries that the strong yen may eat into Japan Inc's earnings, traders said.
"Extreme volatility in the market seems to be overdone, but none of these problems has been resolved," said Hikaru Sato, a senior technical analyst at Daiwa Securities, adding that the next focus would be the G20 meeting next week.
As economic leaders from G20 nations prepare to meet in Shanghai next week, there is increasing market speculation that the world's largest economies, notably G7 countries, may produce a coordinated policy response to global market ructions and slowing growth.
The dollar was at 114.09 yen, having pulled back from a one-week high of 114.875 reached overnight. Continuación...
