TOKYO, Jan 13 (Reuters)- Japan's Nikkei average fell 0.9 percent on Wednesday, hurt by profit-taking and a strong yen, while resource shares slipped after China's decision to start tightening monetary conditions sparked concerns the move might slow demand.
China surprised world markets by raising banks' reserve requirements, the strongest of a series of step towards tightening monetary policy, in response to increasing concerns about its economy overheating. [
]"The Japanese stock market had become overheated following a big rally since December. On top of that, we now have China's decision to raise banks' reserve requirements," said Tsuyoshi Segawa, an equity strategist at Mizuho Securities.
"It's hard to think the move would hinder China's economic recovery, but the news likely led some risk money to close positions for now."
The benchmark Nikkei <
> shed 98.62 points to 10,780.52 after closing at a 15-month high on Tuesday. The broader Topix < > dipped 0.6 percent to 948.52.Analysts noted that the Nikkei, which is hovering around 15-month highs, had been overbought and was poised for profit-taking even before the China news broke after Tokyo market hours on Tuesday.
The Nikkei's relative strength index (RSI) on Tuesday rose to 72. Over 70 is considered overbought territory, so market players said some downward adjustment -- particularly in resource shares, which have gained recently -- was only natural.
CHINA-LINKED STOCKS DOWN
The China move spurred selling in shares of metal stocks as commodities prices fell on concern that the country's purchases of natural resources might slow, while construction machinery firms, which have a big presence in China, also came under pressure.[
