HONG KONG, Sept 18 (Reuters) - Hong Kong shares ended 0.67 percent lower on Friday, a pull back from the previous session's 13-month high on concern that gains were overextended, but accelerating optimism for an economy recovery limited the decline.
Ample liquidity also gave hope for further gains, allowing local stocks to ignore a sharp decline in the mainland market, brokers said.
The benchmark Hang Seng Index slid 145.06 points to 21,623.45, but ended the week up 2.2 percent in the third consecutive weekly gain.
The China Enterprises Index, which represents top locally listed mainland Chinese stocks, eased 0.42 percent to 12,614.57.
China's key stock index the Shanghai Composite Index fell more than 3 percent breaching key 3,000-point level to close at 2,962.667 on concern over upcoming new issues. (Reporting by Donny Kwok; Editing by Chris Lewis)
