ESMA reports on accepted market practices under MAR

16 January 2019

The European Securities and Markets Authority (ESMA) has published today its annual report on the application of accepted market practices (AMP) in accordance with the Market Abuse Regulation (MAR). AMPs are a defence against allegations of market manipulation. In particular, dealings in financial markets which are carried out for legitimate reasons and in conformity with an established AMP will not constitute market manipulation.

ESMA’s report provides an overview on the establishment and application of AMPs in the EU, with particular reference to the AMPs established on the basis of the Market Abuse Directive and which were still in force when MAR became applicable, and the AMPs which have been established under MAR.

The report includes ESMA’s views on the application of AMPs together with recommendations to National Competent Authorities.


MAR’s purpose is to guarantee the integrity of European financial markets and promote investor confidence. The concept of market abuse typically consists of insider dealing, unlawful disclosure of inside information, and market manipulation.

However, some exceptions apply, for example, MAR provides a defence against market manipulation if the transaction was legitimate and carried out in accordance with an AMP and MAR describes the non-exhaustive factors that a competent authority should take into account before deciding whether or not to accept a market practice.
