Mainland stocks on Friday regained almost all the ground lost in on Thursday, but still posted their biggest weekly fall in five months as a stellar bull run peters out.

In Hong Kong, the benchmark Hang Seng Index finished trading for the week up 359 points, or 1.43 percent, at 25,417.

The Hang Seng China Enterprises Index climbed 1.34 percent to end at 9,057.22 points, and the Hang Seng Tech Index hiked 1.95 percent to end at 5,687 to register its fifth straight week of gains.

The benchmark Shanghai Composite Index closed up 1.24 percent at 3,812, above the key psychological level of 3,800.

For the week, it declined 1.2 percent.

The Shenzhen Component Index closed 3.89 percent higher at 12,590, with combined turnover of these two indexes standing at 2.3 trillion yuan, down from 2.54 trillion yuan on Thursday.

The ChiNext Index gained 6.55 percent to close at 2,958.

Stocks in the solid-state battery, photovoltaic and third-generation semiconductor sectors led gains while banking and dairy stocks saw the biggest decline.

China's blue-chip CSI300 Index bounced 2.2 percent.

It was down 0.8 percent for the week, its biggest drop since late July.

Tech shares, which bore the brunt of Thursday's losses, led the recovery on Friday.

The AI sector was up 5 percent and semiconductor stocks climbed three percent.

The start-up board index surged 6.6 percent, its best single-day gain in 11 months.

Chip designer Cambricon also jumped 6.6 percent after sinking some 20 percent earlier in the week.

Traders said there was buying on dips after a wave of profit-taking that followed China's largest-ever military parade subsided.

Markets have also largely shaken off the jitters triggered by a Bloomberg News report that Beijing is considering measures to curb excessive stock speculation.

China's central bank said on Thursday it would inject one trillion yuan into the banking system on Friday via outright reverse repo operations to keep liquidity "reasonably ample", interpreted by some as a gesture aimed at calming investors.

Shanghai's benchmark index had shot to 10-year highs over the past two months, powered by record sums of leveraged bets chasing the rally.

Analysts at China Securities said trading could remain volatile in the near term as the market enters a consolidation period.

"Taking some of the air out of the frothy part of the market is setting up for a more sustainable path down the line," said Jerry Wu, a portfolio manager at Polar Capital, based in London.

"It will be a healthy correction and I don't think it changes the direction of travel, which we do believe is a sort of innovation-driven rally." (Reuters/Xinhua)
