If all investors do not have access to twitter, it is a violation of Reg FD.
Reg FD states that when a publicly traded company or issuer of stock discloses any material nonpublic information regarding that issuer or its securities to a limited group of individuals, the issuer must also make public disclosure of that information. Such disclosures must be made simultaneously if it is an intentional release of information. Non-intentional sharing of such information must be promptly followed with public disclosures.
