Commission Directive 2003/124/EC of 22 December 2003 implementing Directive 2003/6/EC of the European Parliament and of the Council as regards the definition and public disclosure of inside information and the definition of market manipulation (Text with EEA relevance) · European Union

(1) Reasonable investors base their investment decisions on information already available to them, that is to say, on ex ante available information. Therefore, the question whether, in making an investment decision, a reasonable investor would be likely to take into account a particular piece of information should be appraised on the basis of the ex ante available information. Such an assessment has to take into consideration the anticipated impact of the information in light of the totality of the related issuer's activity, the reliability of the source of information and any other market variables likely to affect the related financial instrument or derivative financial instrument related thereto in the given circumstances.
