Mainland stocks were mixed on Friday, ending the week roughly flat, as heightened regulatory efforts to curb speculative trading tempered risk appetite.

In Hong Kong, the benchmark Hang Seng Index was up 119 points, or 0.45 percent, at 26,749.

The China enterprises index was up 46 points, or 0.51 percent, at 9,160 and the tech index was up 35 points, or 0.62 percent, at 5,798.

Alibaba's Hong Kong shares hit a near three-month high on a report that it will be listing its chip-making arm T-Head.

The benchmark Shanghai Composite Index ended up 13 points, or 0.33 percent, at 4,136 while the Shenzhen Component Index was 112 points, or 0.79 percent, higher at 14,439.

The ChiNext Index, tracking China's Nasdaq-style board of growth enterprises, was 20 points, or 0.63 percent, up at 3,349.

The combined turnover of the main Shanghai and Shenzhen indexes was 3.09 trillion yuan, up from 2.69 trillion yuan on Thursday.

Stocks related to furniture, non-ferrous metals and aircraft manufacturing led gains while the ceramics and financial sectors saw major losses.

The Star Composite Index, which reflects the performance of stocks on China's sci-tech innovation board, closed 1.85 percent higher at 1,899 while the Star 50 Index, which tracks the largest stocks that meet certain liquidity requirements, closed 0.78 percent higher at 1,553.

Over the past week, Shanghai and Shenzhen stock exchanges took regulatory measures against hundreds of abnormal trading practices, such as price pumping and false orders.

The bourses also launched probes into several listed companies over allegedly misleading statements.

The measures reflect regulators' intention to slow the pace of market gains.

Last week, China tightened margin financing requirements after the Shanghai market hit decade-highs in record turnover.

"Despite the latest tightening measures, we continue to believe that liquidity support for both A-shares and the Hong Kong market can be sustained, at ⁠least through the first quarter," analysts at Morgan Stanley said in a note.

"Reallocations from bonds and term deposits, together with steady insurance inflows remain the core drivers of improving A-share liquidity," they said.

Non-ferrous metal shares rose 2.7 percent while defence shares climbed 3.3 percent, leading gains onshore. (Reuters/Xinhua)
