Hong Kong shares fell on Thursday as investors were spooked by an unexpectedly sharp drop in China's industrial profits. The Hang Seng index fell 0.8 percent, to 23,132.35, while the China Enterprises Index lost 0.9 percent, to 9,608.91 points. Most sectors were down, led by energy stocks. China's CNOOC fell to a week low after it reported a 15-percent drop in Q3 revenue, pushing lower the shares in the other two oil giants Sinopec and PetroChina, while profit-taking in coal stocks after recent strong gains dragged on the sector. Great Wall Motor shed 4.3 percent, tumbling as much as 16.5 percent in two straight sessions as HSBC and Nomura cut its ratings after it reported Q3 results.
