(Yicai Global) Sept. 15 -- China's main indices dropped further after opening down in this morning's trade, weighed down by resource shares, while realty stocks revived following yesterday's rally.

At 9.55 a.m., the Shanghai Composite Index dropped 0.61 percent to 3,350.99 points, compared with its decline of 0.19 percent at opening.

The Shenzhen Component Index hovered at 11,036.2 points, down 0.31 percent, in contrast with its 0.11 percent at the opening bell.

The Growth Enterprise Index slipped 0.42 percent to 1,871.44 points, and the index kicked off 0.11 percent lower.

As commodity prices slid, resource stocks led the losers, while real estate shares continued their advance, since the commodity home inventory has fallen to an almost 31-month nadir.

The area of commercial housing for sale fell 12 percent yearly to hit a new low since January 2015 at the end of last month, per data the National Bureau of Statistics outed yesterday.
