The Australian Securities and Investments Commission (Asic), the Australian regulator, has found no wrongdoing following its enquiry into unusual futures trading ahead of insurer AMP's demerger announcement.

Asic launched a review of trading into late movements in the SPI 200 futures contract on April 30 to determine if the unusually high movement could have been a result of insider knowledge of AMP's demerger plans, made public on May 1.
