A-shares fell broadly Wednesday with contracted trading volume. Shanghai Composite was closed 0.46% lower at 3273.83 points and Shenzhen Composite 0.76% lower at 2007.00 points. From a sector view, Xiong'an shares were still doing well but stock prices polarized between high and low performance shares.

It's important to take a long term view when trading concept stocks. However, since no news about Xiong'an New Area is ever heard before setting up, it might be hard to do long term trading.

The plunged rate should have been within a proper range later the afternoon session. But stocks of Ping'an and Industrial Bank somehow were sold into correction at the closing bell, dragging share indexes lower. Usually, investors will be anxious if weighted stocks start to collapse. That is how the balance is broken.

Currently, the market is struggling to make headways. But there seems little chance to do so if no government support is given. At the moment, investors have to control your position size and wait for more opportunities. Central bank's open market operations and changes of foreign exchange rate should be closely watched.
