Large shifts in the A-share market were mainly caused by weak economic readings in May, which added deflationary pressure to China's economy and influenced market expectations, said Guangzhou-based Wanlong Stock Consulting company.

China's consumer price index (CPI), a main gauge of inflation, grew 1.2 percent year on year in May, narrowed from 1.5 percent posted in April, the National Bureau of Statistics (NBS) said on Tuesday.

The producer price index (PPI), a measure of wholesale inflation, slid 4.6 percent year on year, the 39th straight month of declines.

Monetary policy must remain on a loosening course until deflationary pressure eases, according to a report by China International Capital Corporation (CICC).
