HONG KONG/SHANGHAI, March 17 (Reuters) - Worries about Japan's ongoing nuclear depressed shares in Hong Kong on Thursday, with the Hang Seng Index dropping more than the Nikkei did.
The benchmark index dropped 1.8 percent, compared with the Nikkei's 1.4 percent decline. The Shanghai Composite , China's main stock index, slipped 1.1 percent, led by nuclear power equipment makers.
Hong Kong's drop to 22284.43 also was fuelled by a 10.9 percent plunge by Tencent Holdings , China's most valuable Internet company. The stock, part of the Hang Seng index, dived after reporting its slowest growth in more than three years late on Wednesday.
Tencent "has been outperforming the market," said Tanrich Securities Vice-President Jackson Wong. "Investors are just reducing the premium on the stock."
For Tencent, it was the biggest one-day drop since October 2008, Tencent is still up 14 percent for the year. In a report on Wednesday, Credit Suisse rated the stock as outperform.
Tencent's sharp drop was a key to the Hang Seng breaking a four-month long consolidation pattern for the Hang Seng, which closed at 22284.43. Further worsening the technical outlook were several large caps close to or breaking below support levels.
HSBC Holdings , the stock with the biggest weight on the benchmark, fell 1.7 percent to HK$79.00, its lowest close since Dec. 1, when it ended at HK$78.55.
China Mobile fell 2.6 percent to HK$69.30, its lowest close since the end of 2009.
Meanwhile, non-nuclear energy issues continued their bullish trend, bucking downside pressures as China suspended nuclear approvals.
China Longyuan Power Group Corp Ltd , one of China's largest wind power producers, gained 3.84 percent after rising 3.7 percent on Wednesday.
"I think this is a case of investors rotating their funds and speculating," said KGI Asia Chief Operating Officer Ben Kwong.
CHINA'S SAFETY CRACKDOWN
China's vast nuclear push is likely to slow after the government ordered a safety crackdown on Wednesday in the wake of Japan's nuclear crisis.
The benchmark Shanghai Composite Index ended at 2,897.3 points. The index rose 1.2 percent on Wednesday.
"Many uncertainties are weighing on the market, which are hurting investor sentiment," said Zhang Qi, a senior analyst at Haitong Securities in Shanghai.
Dongfeng Electric Corp , a leading nuclear power generation equipment manufacturer, dropped 7.6 percent to be the biggest loser on the Shanghai market, while China First Heavy Industries was down 6 percent.
