(Yicai Global) Feb. 27 -- Stock markets on the Chinese mainland went into lunch mixed today as investors considered the potential effect of recent rapid gains on domestic equity markets.

The Shanghai Composite Index was 0.79 percent higher at 2,964.77 going into the lunch break, while the Shenzhen Component Index was up 0.17 percent at 9,104.20. The ChiNext Price Index, which tracks growth enterprises in Shenzhen, fell 0.22 percent to 1,543.53.

Trading volume slipped to CNY500 billion (USD75 billion) after yesterday morning's CNY675 billion -- which laid the foundations for a multi-year high full-day volume -- as many investors anticipated new guidance while others looked to cash out on their recent gains.

China's stock markets have been hot ever since resuming trading on Feb. 11 after the week-long Chinese New Year holiday, with the three major indexes setting multi-month highs early this week. The cumulative rise of each of the indexes was between 14.4 percent and 28.3 percent at yesterday's intraday peaks.
