Abstract: The study aims to provide a short presentation of new general legal framework in EU concerning insider trading as a part of market abuse. Market abuse consists of insider dealing and market manipulation. The objective of legislation against insider dealing is the same as that of legislation against market manipulation: to ensure the integrity of Community financial markets and to enhance investor confidence in those markets. Thus there have been adopted combined rules to combat both insider dealing and market manipulation. Directive 2003/6/EC aim to ensure throughout the Community the same framework for allocation of responsibilities, enforcement and cooperation.

Key-words:  market abuse, inside information, financial instruments.
