News releases AMF: 2016

The consequences of the serious market dysfunction relative to the Vinci share

Published on November 23, 2016

Yesterday, following the circulation of false news releases disseminated by the press agencies, the Vinci share temporarily lost 18% during the day’s trading before making a rapid recovery.

The Autorité des marchés financiers considers this to be a serious market dysfunction for which it will endeavour to determine the responsibilities involved.

This is a case of the dissemination of false information, which prompts the AMF to carry out an investigation. It will also be necessary to verify who may have taken advantage of such an initiative through a possible manipulation of prices.

The AMF will also be working with all the entities involved so as to limit this type of risk in the future and its impact on the financial markets.
