China's Financial Times media outlet with a report that Shenzen and Shanghai exchanges said those who hold shares will not be able to lend them out for short-selling outside of a lockup period:

  • rules to be implemented in March
  • China Securities Regulatory Commission says this will create a more fair market order


Seeing if I can dig a little more on this, it seems strange they'd be waiting until March.
