Sept 13 (Reuters) - Hong Kong and China shares fell on Friday, led by Chinese cyclical counters from banks to materials as investors booked profits after robust gains earlier in the week.
At midday, the Hang Seng Index was down 0.5 percent at 22,836.4 points, while the China Enterprises Index of the top Chinese listings in Hong Kong shed 1.4 percent.
The indexes are still set for a second-straight weekly gain, up 1 and 1.5 percent, respectively.
The CSI300 of the leading Shanghai and Shenzhen A-share listings fell 0.8 percent, while the Shanghai Composite Index shed 1 percent after closing on Thursday at its highest in three months.
On the week, they are up 5.5 and 4.3 percent, set for their biggest weekly gain since the week that ended Feb. 1. Losses on Friday also knocked the Shanghai benchmark off its most technically overbought level since July 2009.
"I think we are due for more gains and we are recommending clients start accumulating more beta counters in the Chinese banking and property sectors," said Francis Cheung, CLSA's managing director of Hong Kong-China strategy.
"The rally so far has been mainly short covering and some of the long money is beginning to return. So many were so bearish on China earlier this year, so even a return to equal weight will help lift the market," Cheung added.
Still, on Friday some of these beta counters were among the biggest index drags. China Minsheng Bank shed 2.9 percent in Hong Kong and 4.3 percent in Shanghai.
Materials counters were broadly weaker. Zijin Mining sank 3.2 percent in Hong Kong and 1.5 percent in Hong Kong as gold prices head towards their worst week in two months.
China coal counters extended losses as thermal coal stocks at China's top coal port dropped to a three-month low and aggressive sales tactics set to keep a lid on any rebound in domestic prices.
Beijing had also unveiled comprehensive measures to tackle air pollution on Thursday that involve slashing coal consumption.
China Shenhua Energy Co Ltd tumbled 1.7 percent in Shanghai and 4 percent in Hong Kong. Power producers jumped on lower coal prices, with Huaneng climbing 3.5 percent in Hong Kong.
Sun Hung Kai Properties shed 1.8 percent after closing on Thursday at their highest since Aug. 19. The world's second-largest property firm by market value posed a 14 percent fall in full year underlying profit, lagging forecasts while setting a weaker sales target for the next year.
Sino Biopharmaceutical rebounded 1 percent as trading resumed on Friday, after the company said it was not aware of any investigation involving anybody connected to the company.
